While they can be highly destructive, tropical cyclones are an important part of the atmosphere circulation system which moves heat from the equatorial region toward the higher latitude. Keyword: Latitude: The distance of a place north or south from the equator (Places that are near to the equator or much warmer than places that are near the north and south poles. ) How Are Tropical Cyclones Formed 1. Formative - clouds start forming over the ocean between 5 and 15 degrees latitude from the equator. 2. Immature - if the conditions are favorable, clouds collect and move with the winds that start rotating clockwise around a low pressure area.
Winds start to increase in strength. 3. Mature - the cyclone reaches its peak of intensity and destructive power. 4. Decaying - the power of the cyclone decreases when it moves over land or pole ward over colder waters. In this decaying stage the winds often decrease rapidly and the cyclone eye and cloud patterns disappear.
