Describe the distribution of tropical storms
They are found 10-30 degrees north and south of the equator in warm seas of around 27*
Describe the formation of a tropical storm.
Thunderstorms travel over warm seas picking up energy. Warm air rises and due to the earths rotation the mass of cloud will begin to spin. This causes cool air to be sucked into the eye and more warm air to rise. Cool air causes the wind speed to increase and as the storm travels over the warm oceans picking up more energy and as more energy condenses into the center of the storm the storm becomes more powerful
