triggering factors of typhoon

Tropical cyclones are also generated in disturbances along the intertropical convergence zone, on traverse waves or under superimposed upper disturbances. Do not touch damaged electrical equipment and report power outages to power companies. A squall is defined as an event in which the surface wind increases in magnitude above the mean by factors of 1.2 to 1.6 or higher and is maintained over a time interval of several minutes to one half hour. It is independent of the type of stress and the factors that trigger it. The Regional Specialized Meteorological Center (RSMC) for tropical cyclone forecasts is in Japan, with other tropical cyclone warning centers for the northwest Pacific in Hawaii (the Joint Typhoon Warning Center), the Philippines, and Hong Kong. Anyone you share the following link with will be able to read this content: Sorry, a shareable link is not currently available for this article. At the tropical depression drift, it may encounter areas of the ocean where it is hot. Typhoon Haiyan is called Typhoon Yolanda in the Philipines. While these conditions are necessary for tropical cyclone formation, they do not guarantee that a tropical cyclone will form. In the Philippines, the most active season, since 1945, for tropical cyclone strikes was 1993 when nineteen tropical cyclones moved through the country. Weak vertical wind shear in the basic current so in those areas of small mean zonal-wind shear are also areas of active storm formation. Rainfall associated with tropical cyclones is both beneficial and harmful. Ser. I would love to hear your opinion, question, suggestions, please let me know. Like any tropical cyclone, there are several main requirements for typhoon formation and development. The heat causes more air to flow to the. Bay of Bengal and Arabian Sea from May to June and October to November. A typhoon is a mature tropical cyclone that develops between 180 and 100E in the Northern Hemisphere. Past experience indicates that the main triggering factor for landslides in the study area is heavy rainfall, which can be considered a trigger for landslides in the future. People in areas at risk of flooding should consider a temporary evacuation. During a power outage, switch off all large appliances, report to the building management office, and wait patiently for engineers to do repairs. Typhoon "Basyang" And in the Atlantic, theyre called hurricanes. According to NOAA, hurricanes form in the northern Atlantic, northeastern Pacific, and South Pacific. The French typhon has been attested with the meaning of whirlwind or storm since 1504. The internal factors of landslide formation are related to the soil and rock materials, including (1) soft and weak rock properties or rock strata with multiple joints or shear fracture zone; (2) geological structure; (3) topography; (4) vegetation. ADS The landslide triggering factors include internal, external and human factors. This, in turn, disrupts communication between our brain and other parts of our body. There may be as many as 30 in a year. [citation needed] The word (fn) is also derived from Arabic as coming from fa (), to turn round.[9]. Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper. Restoring electricity may take longer in areas where the damage is severe or access roads are blocked by fallen trees or flooding. Low air pressure causes a slight bulge in the ocean, which adds to the mound of water that causes storm surge. https://doi.org/10.3103/S0027133022020042, DOI: https://doi.org/10.3103/S0027133022020042. With a very active system, clouds can move together into large clusters of thunderstorms. Kamchatskoi Regionalnoi Organizatsii Uchebno-Nauchn. 453, 12571263 (2013). Since a typhoon is just another term for hurricane, the same conditions apply for both. The stage of maturity of the tropical cyclones where the areas of circulation expands while the surface pressure no longer falls and no increase in maximum winds speed can be observed which may last for a week. Some particular ingredients or factors came together to make typhoons. Typhoon "Juan" On the other hand, as the wind blows inward, its speed increases and reaches its maximum value just outside of the "eye" near the surface of the ocean, the winds converge towards the center. Tropical cyclones derive their energy from the latent heat of condensation which made them exist only over the oceans and die out rapidly on land. Based on some studies, the quotient obtained by dividing the wind velocity (probably average for hour) in miles per hour by 2.05 represents the average height in feet of waves developed by the wind. - 64.91.240.67. It is the reverse process of evaporation, which requires considerable amount of heat to evaporate water. Leave one light on so you will know when power has been restored. [17] Even with perfect upper-level conditions and the required atmospheric instability, the lack of a surface focus will prevent the development of organized convection and a surface low. Tracks of Tropical Cyclones that entered the Philippine Area of Responsibility from 2017-2021, Weather Outlook Selected Philippine Cities, Annual Report on Philippine Tropical Cyclones, Ten-Day Regional Agri-Weather Information, Monthly Philippine Agro-Climatic Review and Outlook, Flood Forecasting and Warning System for River Basins, National Meteorological and Hydrological Services, Approved Budget and Corresponding Targets, Status of Implementations of Program/Projects. Keep fridge doors closed. by V. V. Adushkin and G. G. Kocharyan (Geos, Moscow, 2017). [29] Those that form near the Marshall Islands find their way to Jeju Island, Korea. 62 (Vieweg+Teubner Verlag, Wiesbaden, 1985). Subject: A15) How do tropical cyclones form? They always form over oceans where sea surface temperature, also air temperatures are greater than 26C. [37] There was only one tropical cyclone that moved through the Philippines in 1958. Typhoon "Ester" Times, Sunday Times Keep a diary of what you spend when, and look for trigger factors, such as how you were feeling. Move electrical appliances to a safe place. In the bay of Bengal, Arabian Sea and Western South Indian Ocean, the name is"cyclonic". At the top of the storm system, the rising warm air is transported outward and form an anvil-shaped cloud called "cumulonimbus". When wind speeds top 25 knots, about 30 miles per hour, the center issues its First Alert. This makes this basin the most active on Earth. [27] Most typhoons form in a region in the northwest Pacific known as typhoon alley, where the planet's most powerful tropical cyclones most frequently develop. The .gov means its official. Typhoon disasters have caused casualties, property loss, and other negative impacts to social and economic development. Though these heat sources are not sufficient to start a hurricane going, the heat of condensation supports the process once started. On average, the northwestern Pacific features the most numerous and intense tropical cyclones globally. Our study focuses on the triggering factors and dynamic behavior of hail-debris flows affecting the small commune of Malloa (Central Valley), which caused 200 injured individuals and 73 damaged houses. Other limitations include wind patterns in the upper atmosphere and the force of the earths rotation, meaning that hurricanes can only develop around a narrow band between 8 and 20 degrees north of the Equator. SUPER TYPHOON (STY) - a tropical cyclone with maximum wind speed exceeding 185 kph or more than 100 knots. This site needs JavaScript to work properly. Recommended browser : Chrome / Firefox / IE 9, 1024 x 768 screen resolution. A typhoon will weaken if the water is not warm enough. In these situations, stay calm and listen to news bulletins. Typhoons depend on this to remain organized. [6] Elsewhere this is called a tropical cyclone, severe tropical cyclone, or severe cyclonic storm.[7]. Electrical appliances and leads should be moved indoors and kept away from windows. Although the majority of storms form between June and November, a few storms may occur between December and May (although tropical cyclone formation is at a minimum during that time). Fluid and Gas Mechanics (Bashkir. Careers. [12] A tropical depression is upgraded to a tropical storm should its sustained wind speeds exceed 34 knots (39mph; 63km/h). Dont forget to charge your phone and prepare additional power banks fully. Those that form in the South China Sea move generally northward or toward the northeast which also affects the Philippines. Journal of Geophysical Research: Atmospheres: D06108.What is the difference between a hurricane, a cyclone, and a typhoon?. of the 3rd All-Russian Workshop-Meeting, Ed. [19] There is an inverse relationship between tropical cyclone activity in the western Pacific basin and the North Atlantic basin, however. The authors declare that they have no conflicts of interest. The landslide triggering factors include internal, external and human factors. Keywords: These conditions are discussed in greater detail in Tropicalweather.net's, If all of the pre-conditions are met, typhoon formation then becomes possible. This should be used with caution and only as an approximation. (Factors, Formation, Safety). Thus, the typhoon will dissipate once the supply of water vapor is cut-off. The first character is normally used to mean "pedestal" or "stand", but is actually a simplification of the older Chinese character , which means "typhoon"; thus the word originally meant "typhoon wind". One of the most recent busy seasons was 2013. The swell moves with a speed of three or four times greater than the speed of the storm center. The combination of upwelling and vertical mixing typically produces a decrease in the surface ocean temperature of 1-3C and may occasionally produce a decrease as large as 5C which affects the intensity of slow-moving or stationary storms by reducing evaporation into the atmosphere. These waves will be under the influence of the strong winds for a long time, and we say that the fetch is large. Can The tpms sensors on a 2002 Ford Explorer can be activated using a magnet.. The primary external factors that can trigger a landslide include: (1) weathering of rock strata; (2) increased pore water pressure, such as the infiltration of rainwater or rise of groundwater surface; (3) increased loading by, for example, rainfall, accumulated snow or flourish vegetation; (4) the supporting forces of toe have been removed by, for example, weathering, erosion, early landslide or faulting; (5) collapse of underlying strata; (6) an increase in lateral pressure, such as rock fissure, freezing water; expansion of clay materials and so on; (7) earthquakes and vibrations; (8) torrential rains; (9) other factors, such as site subsidence resulted from limestone cave. A minimum distance of 500km (300mi) from the equator is normally needed for tropical cyclogenesis. Epub 2020 May 4. Building managers should consider engaging contractors to conduct inspections before typhoons and carry out any improvement works needed. They pass at incredible speeds through certain substances they can polarize like water. Below are the frequencies of tropical cyclones per 10 years in the different areas where tropical cyclones are formed: North Pacific, off West Coast of Mexico - 57, South Indian Ocean, Northwestern Australia - 9. A typhoon is a huge storm with a very strong wind speed in tropical areas. So its a prime location for developing thunderstorms and the birthplace of most hurricanes. Chair of Gas and Wave Dynamics, Faculty of Mechanics and Mathematics, Lomonosov Moscow State University, Moscow, Russia, You can also search for this author in To the left of the storm track, the waves are under the influence of the wind for a relatively short time, and we say that the fetch is small. I'm the author of this blog. They travel upwards until they meet with cold air. [3][4], The term typhoon is the regional name in the northwest Pacific for a severe (or mature) tropical cyclone,[5] whereas hurricane is the regional term in the northeast Pacific and northern Atlantic. The intensity of tropical cyclones vary, thus , we can classify them based upon their degree of intensity. Also, it keeps the temperature and heat at an equilibrium state. Now the swell generated in the rear right quadrant will move forward in the direction of the movement of the storm. Natyaganov, V.L., Skobennikova, Y.D. The dissipating stage of the tropical cyclone where the surface pressure rises and the area affected by the cyclones diminishes in size as it recurves or dissipate due to friction and lack of moisture over continents or when colder and drier air enters through when they go poleward. H. G. Hahn, Elastizitatstheorie: Grundlagen der linearen Theorie und Anwendungen auf eindimensionale, ebene und rumliche Probleme, Leitfden der angewandten Mathematik und Mechanik, vol. Typhoon melor triggering turbidity currents off the MT delta Some of the planet's most powerful typhoons follow generally straight westward trajectories, crossing the Philippines at their . Save my name, email, and website in this browser for the next time I comment. Through this process, an average-sized typhoon will get an energy supply in one day equivalent to the energy release by 40,000 hydrogen bombs. Bull. 12th All-Russian Congress on Fundamental Problems of Theoretical and Applied Mechanics. Using the aforementioned regressive process, accumulative rainfall and peak ground acceleration (PGA) are selected as the major triggering factors in this research. Stay calm during power outages. Further away from the center, at the tip the air becomes colder and dry and starts "sinking" downward. In the eastern part of the Southern Indian Ocean, it is "willy-willy", and in the Western North Pacific Ocean, they are called "typhoons". [8] The Oxford English Dictionary[9] cites Hindustani fn and Chinese tai fung giving rise to several early forms in English. The frontal theory indicates that many tropical cyclones form along the front between the trade winds and the equatorial air in the doldrums . What 2 properties of minerals can be expressed in numbers? About 85 to 90percent of Pacific typhoons form within the monsoon trough. There are perhaps seven atmospheric conditions which, if met, could cause a typhoon to form. Influence of rainfall on landslides Rainfall, especially from storms, is the dominant factor inducing landslides. Moisture: Even with warm water, a typhoon can encounter dry air masses, which can enter into a typhoon and weaken it or prevent it from strenghtening. Tropical storms also receive official names from RSMC Tokyo. FOIA Also, it keeps the temperature and heat at an equilibrium state. In the Indian Ocean and southwest Pacific, theyre called cyclones. The condensation of the water vapor causes the release of the latent heat trapped within it. Its impact is greatest over the coastal areas, which bear the brunt of the strong surface winds, squalls, induced tornadoes, and flooding from heavy rains, rather than strong winds, that cause the greatest loss in lives and destruction to property in coastal areas. [12] Should the storm intensify further and reach sustained wind speeds of 48 knots (55mph; 89km/h) then it will be classified as a severe tropical storm. A large portion of the solar energy reaching the sea-surface is expended in the process of evaporation. Chan EYY, Man AYT, Lam HCY, Chan GKW, Hall BJ, Hung KKC. There are several major factors affecting typhoons. The convergence of the two air masses results in the upward motions which in addition to the deflective effect of the earth's rotation, centrifugal force , and divergence at the upper levels results in allow pressure area with a spiral circulation toward the center. Tropical cyclones are warm-core low pressure systems associated with a spiral inflow of mass at the bottom level and spiral outflow at the top level. The curl of the stress generates divergence in the upper layer of the ocean, producing regions of upwelling and downwelling . Focusing on the vulnerability measures of Typhoon Hato in 2017 and Typhoon Mangkhut in 2018, this study aims to quantify the contribution and interactive effects of physical and socioeconomic factors on vulnerability based on the GeoDetector method and determine the factors that account for most of the change in vulnerability. [29] During La Nia years, the formation of tropical cyclones, and the subtropical ridge position, shift westward across the western Pacific Ocean, which increases the landfall threat to China and greater intensity to Philippines. During the Southern Hemisphere Summer, the intertropical front in these areas moves only a degree or so south of the equator which is not far enough for the coriolis force to become effective. Required fields are marked *. TROPICAL STORM (TS) - a tropical cyclone with maximum wind speed of 62 to 88 kph or 34 - 47 knots. ", "typhoon | Origin and meaning of typhoon by Online Etymology Dictionary", "What are the description labels used with tropical cyclones by JTWC? Bethesda, MD 20894, Web Policies D. G. Levchenko, Registering Wide-Band Seismic Signals and Possible Forerunners of Major Earthquakes at the Sea Bottom (Nauchnyi Mir, Moscow, 2015). The most active Western Pacific typhoon season was in 1964,[citation needed] when 39storms of tropical storm strength formed. Typhoon "Katring" Serious complications are rare but can include intestinal bleeding or perforations in the intestine. The https:// ensures that you are connecting to the Stock up on emergency supplies before a typhoon comes. Simultaneous with the warming of water masses along their way from east to west in the individual oceans within west Pacific regions heating, and, owing to the strong evaporation, an increase in water vapor in the lower atmosphere occur, both of which contribute to the instability of the atmospheric layers. [26], Most tropical cyclones form on the side of the subtropical ridge closer to the equator, then move poleward past the ridge axis before recurving north and northeast into the main belt of the Westerlies. Larger storm surges are more likely along coasts that bow inward than those that bow outward. Migraine has possibly been associated with the previous ingestion of certain foods (about . Exhaust: These tropical systems are cyclonic at their base but antipsychotic in the upper atmosphere, which allows them to move away from the center of circulation. For riverine situations, the surge is sea water moving up the river. The highest reliably-estimated maximum sustained winds on record for a typhoon was that of Typhoon Haiyan at 314km/h (195mph) shortly before its landfall in the central Philippines on November 8, 2013. Tropical cyclones form over oceans of the World except in the South Atlantic ocean and in the South eastern Pacific. S. A. Maslov, V. L. Natyaganov, and Yu. For storms that have affected countries in this basin: Type of tropical cyclone that develops in the Northern Hemisphere, This article is about Northwestern Pacific tropical cyclones. An extreme precipitation event produced catastrophic debris flows in central Chile during 29-31 January 2021 (austral summer). https://doi.org/10.1007/978-3-663-09894-2. The warning is, however, not very precise, for it provides no information on the behavior of the storm since the swell left it. All storms are forming in the northern hemisphere and spin counterclockwise. Typhoons develop best when there is little to no wind shear. In the North Atlantic, Eastern North Pacific and South Pacific Ocean, they are called"hurricanes". What Causes A Hurricane To Form With Survival Tips, How Does A Tsunami Occur In Tropical Area, What Causes A Tornado To Form In Tropical Area, Safety precautions during and after Typhoon. Who makes the plaid blue coat Jesse stone wears in Sea Change? Whether it be a depression in the Intertropical Convergence Zone (ITCZ) or monsoon trough, a broad surface front, or an outflow boundary, a low level feature with sufficient vorticity and convergence is required to begin tropical cyclogenesis. For organizational purposes, the northern Pacific Ocean is divided into three regions: the eastern (North America to140W), central (140W to 180), and . 2022 Feb;256(2):175-185. doi: 10.1620/tjem.256.175. Price excludes VAT (USA)Tax calculation will be finalised during checkout. And the consequences of flooding can be savage. [13] The United States' Joint Typhoon Warning Center (JTWC) unofficially classifies typhoons with wind speeds of at least 130knots (67m/s; 150mph; 241km/h)the equivalent of a strong Category4 storm in the Saffir-Simpson scaleas super typhoons. For a typical storm, the surge affects about 160 km of coastline for a period of several hours. [17], In general, the westerly wind increases associated with the MaddenJulian oscillation lead to increased tropical cyclogenesis in all tropical cyclone basins. Rain intensity and wind intensity are the dominant factors of disaster loss for Typhoon Hato and Typhoon Mangkhut, respectively. In other parts of the world, these are referred to as hurricanes, typhoons or simply tropical cyclones depending on the region. Although there were some differences between the subgroups of ABDs, the onset of the disease was associated with a triggering factor (stress, foods, physical . Tropical cyclones can only form over oceans of the world except in the South Atlantic Ocean and the south eastern Pacific where a tropical cyclone could never be formed due to the cooler sea surface temperature and higher vertical wind shears. [14] However, the maximum sustained wind speed measurements that the JTWC uses are based on a 1-minute averaging period, akin to the U.S.'s National Hurricane Center and Central Pacific Hurricane Center. They reach their greatest intensity while located over warm tropical water. The magnitude of waves is dependent not only upon the fetch, but also upon the wind velocity. Before Would you like email updates of new search results? Instead, they generally refer to animals, flowers, astrological signs, and a few personal names. Turbulence is also generated in the ocean by the wind stress and this turbulence mixes warm surface waters with deeper cooler water. with Int. Whether or not these stresses (driving stresses) are capable of triggering failure of a given slope at a given moment in time will depend on the relative magnitude of the stresses that resist the tendency for failure; these opposing stresses can be referred to as resisting stresses. Overall, the results can be conducive to understanding the complexity of vulnerability to typhoons and provide a reference for possible indicators for vulnerability assessment models, and determining the reasons for changes in vulnerability can be constructive to the formulation of specific policies for disaster prevention and mitigation. Stock up on food, water, medicine, radios, and flashlights. One of its distinguishing features is its having a central sea-level pressure of 900 mb or lower and surface winds often exceeding 100 knots. Source : Central Geological Survey, MOEA. They are given below. government site. Strong winds can easily cause buildings to collapse, as well as destroying roads and infrastructure. The deepening stage of the cyclone during which it continues to deepen until the lowest central pressure and the maximum wind intensity are reached. Humidity: It is also another essential aspect. When large amounts of heat energy collide with an unstable atmosphere, Coriolis force, upper atmosphere divergence, or a moist. 2020 Aug 20;731:139093. doi: 10.1016/j.scitotenv.2020.139093. In latter information, we can concede that tropical cyclone is closely related to ocean. When favorable conditions exist the interaction leads to the formation of the most destructive phenomenon, tropical cyclone formation. In Vietnamese, " " (i phong) translates literally to "strong winds", but the phrase "bo nhit i" ( 'Ferocious tropical storm') is used instead. Initial disturbances from which storms later developed may be detected within 5 of latitude of the equator, but these disturbances do not intensify into typhoons or hurricanes until they are more than 5 of latitude from the equator (since the value of the coriolis parameter should be larger than a certain minimum value. The Philippines is prone to tropical cyclones due to its geographical location which generally produce heavy rains and flooding of large areas and also strong winds which result in heavy casualties to human life and destructions to crops and properties. These development near landfall lead to unexpectedly large damage. Direct loss; Emergency transfer; Hazard intensity; Typhoon; Vulnerability. When large mid-atmosphere a typhoon forms. Spatial pattern of the population casualty rate caused by super typhoon Lekima and quantification of the interactive effects of potential impact factors. If the warm water extends deep, to about 200 meters or so, a storm can strengthen further. [35] Storms that cross the date line from the central Pacific retain their original name, but the designation of hurricane becomes typhoon. The two other conditions were being mentioned in the theories of formation. North Pacific off the West Coast of Central America during the months of June to October. A typhoon is a mature tropical cyclone that develops in the western part of the North Pacific Ocean between 180 and 100E. These are the "convective theory" and the "frontal" or "counter-current" theory. L. N. Doda, V. L. Natyaganov, and I. V. Stepanov, An empirical scheme of short-term earthquake prediction, Dokl. They start from evaporating water molecules from the ocean because this moist air is warm. https://doi.org/10.1038/27650, Article What word names an Ordered list of number? Most typhoons strike in the northern part of the Philippines. Vulnerability is an important component of typhoon risk. Some recent studies on landslides in . Storm surge is the abnormal rise in sea level at the coast during the passage of an intense tropical cyclone (TC), usually land falling or touching land. Taiwan has received the wettest known typhoon on record for the northwest Pacific tropical cyclone basins. When the sun heats up the earth surface, water vapor evaporates into the atmosphere and condenses into water droplets, a great amount of heat energy, which is locked up in the water vapor, is released. Diet. In addition, imbalances between the current velocities and pressure field in the ocean lead to eddies which between the current velocities and pressure field in the ocean lead to eddies which persists far behind the storm. For different loss types, the dominant socioeconomic vulnerability factor is different. A typhoon will weaken if the water. Part of Springer Nature. What to do during the typhoon and after the typhoons? Some of external landslide triggering factors are counted as human factors. 1. 2019 May 8;16(9):1614. doi: 10.3390/ijerph16091614. The first involves the gradual buildup of strain in an earthquake fault zone. The storm surge is an abnormal rise of water due to a tropical cyclone and it is an oceanic event responding to meteorological driving forces. The dominant interaction effects between two vulnerability factors differ depending on the typhoon and loss type but show a nonlinear enhancement effect in most cases. Unlike tropical cyclones in other parts of the world, typhoons are not named after people. This page was last edited on 10 January 2023, at 00:40. D. Skobennikova, Mechanical causes of recent activization of the planet and its consequences, in Proc. Although the rains contribute to the water needs of the areas traversed by the cyclones, the rains are harmful when the amount is so large as to cause flooding. Depth of warm water: The waves of a typhoon tend to churn up the ocean, bringing up cooler water from deeper down. Evacuate high-risk areas and unplug electricity before leaving. Mech. M. A. Sadovskii Selected Works: Geophysics and Physics of Explosion (Nauka, Moscow, 2004). Google Scholar. I. Sneddon, Fourier Transforms (McGraw-Hill, New York, 1951). There are perhaps seven atmospheric conditions which, if met, could cause a typhoon to form. Check lifts and carry out improvement works where needed. Trigger Effects in Geosystems: Proc. These clusters of clouds are areas of low pressure in the atmosphere. : Nauki Zemle, No. 4. It is one of the deadly disasters that happens several times per year and creates a huge environmental change. Typhoon "Inday" Landslides are mainly located in the western portion of Dulishan Station. This mound of water follows the storm and contributes to the storm surge when the hurricane makes landfall. For organizational purposes, the northern Pacific Ocean is divided into three regions: the eastern (North America to 140W), central (140W to 180), and western (180 to 100E). Here are eight of the most common causes of flooding, both natural and human-induced. [12] Once the system's maximum sustained winds reach wind speeds of 64 knots (74mph; 119km/h), the JMA will designate the tropical cyclone as a typhoonthe highest category on its scale. It will further drive the increase of its circulation, transforming it into a typhoon. Like other basins, they are steered by the subtropical ridge towards the west or northwest, with some systems recurving near and east of Japan. Land: A typhoon that strikes a large land mass will be cut off from its power source and fairly quickly degenerate into a remnant low. It is associated with changes in sleep pattern, which is also a triggering factor of cephalalgia. Typhoons form like how ordinary ring bells form. Moreover, changes in the maximum 4-hour accumulated rainfall account for most of the change in vulnerability between Hato and Mangkhut. For example, construct a road on top of or below the slope; or prepare the site to have a flat land. buffalo news shooting victims, Storm since 1504 North Pacific off the West Coast of central America during triggering factors of typhoon months of June to..
