![]() ![]() Helicopters flying near waterspouts can be damaged and thrown off-course by such intense winds. A trough for conducting grain, flour, etc., into a receptacle. Waterspouts not only put swimmers and boaters at risk, they also pose a threat to aircraft. That through which anything spouts a discharging lip, pipe, or orifice a tube, pipe, or conductor of any kind through which a liquid is poured, or by which it is conveyed in a stream from one place to another n. The National Weather Service recognizes the dangers posed by waterspouts as part of its "severe local storm" warning list. The largest waterspouts can have diameters of 100 meters (330 feet) and last for up to one hour, though the average lifetime is just 5 to 10 minutes. The average spout is around 50 meters (165 feet) in diameter, with wind speeds of 80 kilometers per hour (50 miles per hour), corresponding to the weakest types of tornadoes on land. When the flow of warm air into the vortex weakens, the waterspout collapses. spout verb I, T (LIQUID) If a liquid spouts or if something makes it spout, it flows out of something with force. spout 1 a) intransitive always + adverb/prepositionPOUR if liquid or fire spouts from somewhere, it comes out very quickly in a powerful stream SYN spurt. It appears to have a hollow funnel and may be surrounded by vapor. The waterspout is now at its most intense stage, visible from the surface of the water to the clouds overhead. It appears to have an eye at the center, similar to that seen in a hurricane. A swirling ring of sea spray called a cascade forms around the dark spot. Light and dark bands spiral out from the dark spot. The surface of the water takes on a dark appearance where the vortex, or column of rotating wind, reaches it. There are five stages of waterspout formation: 1. Waterspouts are most common in tropical and subtropical waters, such as the Florida Keys, the islands of Greece, and off the east coast of Australia. Both tornadic and fair-weather waterspouts require high levels of humidity and a relatively warm water temperature compared to the overlying air. Fair-weather waterspouts are associated with developing storm systems, but not storms themselves. The clouds from which they descend are not fast-moving, so fair-weather waterspouts are often static. Fair-weather waterspouts are rarely dangerous. Fair-weather waterspouts, however, are much more common. Tornadic waterspouts are the most powerful and destructive type of waterspout. Influenced by winds associated with severe thunderstorms, air rises and rotates on a vertical axis. Tornadic waterspouts get their start as true tornadoes. spouts) a tube or lip through which liquid is poured or discharged I dropped my china teapot, and its spout has broken. There are two major types of waterspouts: tornadic waterspouts and fair-weather waterspouts. The water inside a waterspout is formed by condensation in the cloud. A waterspout descends from a cumulus cloud. Despite its name, a waterspout is not filled with water from the ocean or lake. A waterspout is a column of cloud-filled wind rotating over a body of water. If something spouts liquid or fire, or if liquid or fire spout out of something, it comes out very quickly with a lot of force. ![]()
