Tropical cyclones have different names, depending on where they develop. In the Atlantic and eastern Pacific Oceans, they are called hurricanes. In the Indian Ocean they are known as cyclones and in the eastern Pacific they are identified as typhoons.
Tropical cyclones are storm systems of low pressure surrounded by a complex spiral of thunderstorms. Unlike mid-latitude cyclones, tropical cyclones do not form in regions with fronts. Rather, hurricanes develop where the atmosphere is relatively homogenous – but with a high pressure aloft to “cap” the low pressure storm. These storm systems rely on energy from warm water to develop, and as such, form in low latitudes.
