Warm ocean waters (at least 80°F/27°C).An unstable atmosphere driven by differences in temperature, where temperature decreases with height. Moist air near the mid-level of the atmosphere. Must be at least 200 miles (with rare exceptions) north or south of the equator for it to spin (due to the Coriolis effect )., and more items.
Where do tropical storm to form on earth?
Tropical cyclones occur over the ocean in areas near the equator. This is because there is plenty of warm water in these areas to allow the storms to form . There are seven major areas in the world that tend to produce tropical cyclones.
Where are most tropical storms located?
Includes the waters of: the Southern Pacific Ocean between a longitude of 140 degrees east and 140 degrees west Official Season Dates: November 1 to April 30Season peak dates: late February/early March. Storms are known as: tropical cyclones.
Tropical cyclones occur in the tropical regions over warm ocean water. In the North Atlantic, they are called hurricanes; in the North Pacific, they are called typhoons; and in the Indian Ocean, they are called cyclones. Hurricanes start as tropical depressions with wind speeds of at least twenty-five miles per hour.
Only two tropical ocean basins do not support tropical cyclones, because they lack waters that are sufficiently warm. The Peru Current in the eastern South Pacific and the Benguela Current in the South Atlantic carry cool water Equatorward from higher latitudes and so deter tropical cyclone development.
Answer: The average hurricane moves from east to west due to the tropical trade winds that blow near the equator (where hurricanes start). When a hurricane is still in the Caribbean, the tropical jet blows east to west, and the hurricane moves west to gain power.
What conditions are needed for a tropical storm?
Tropical Storms start within 5º and 30º north and south of the equator where surface sea temperatures reach at least 26.5ºC. The air above the warm sea is heated and rises. This causes low pressure. As the air rises it cools then condenses, forming clouds. The air around the weather system rushes in to fill the gap caused by the rising air.
