Tropical cyclones initially move westward (owing to easterly winds) and slightly towards the poles. An atmospheric flow that transports vast amounts of moisture to regions outside of the tropics. Tropical cyclones tend to develop during the summer, but have been noted in nearly every month in most tropical cyclone basins. These systems, when making landfall, can cause massive and devastating wind and flood damage. Hurricanes start as tropical depressions with wind speeds of at … ... -When tropical cyclones form over warm ocean waters,the intense low pressure in the eye of the cyclone causes the sea level to rise.-Strong winds push the water towards the coast and create huge waves,giving rise to a storm surge. When autocomplete results are available use up and down arrows to review and enter to select. Unlike the Western Hemisphere, where tropical storms and hurricanes mostly form north of the equator, tropical cyclones in the Eastern Hemisphere develop over very warm waters found both north and south of the equator.Their individual tracks through the ocean basins are influenced by sea surface temperatures, air currents, and the subtropical highs—belts of high pressure in the … Well, they aren’t usually, but it’s possible.
