How do tropical cyclones form BBC Bitesize?

How are tropical cyclones formed BBC Bitesize?

Tropical storms usually form between 5° and 30° latitude. When the ocean surface waters reaches at least 27°C due to solar heating, the warm air above the water rises quickly, causing an area of very low pressure. As the air rises quickly more warm moist air is drawn upwards from above the ocean creating strong winds.

How is a tropical cyclone formed?

Tropical cyclones are formed only over warm ocean waters near the equator. When warm, moist air over the ocean rises upward from near the surface, a cyclone is formed. When the air rises up and away from the ocean surface, it creates an area of lower air pressure below.

A cyclone is formed when warm, moist air near the ocean’s surface rises upward. When air rises away from the ocean’s surface, it generates a low-pressure zone beneath it. It causes air from higher-pressure places to travel towards the low-pressure area, warming the air and causing it to climb above.

What are the main causes of tropical cyclones?
