Question 3

Formation of tropical cyclones

Answer 3

-strong clusters of thunderstorms drift over warm water at 26.5 degrees
- warm air from storm and ocean surface combine and begin rising creating lownpressure at surface
- rising warm causes pressure to decrease at high altitudes and wind make them spin outwards
- air rises faster and faster drawing warm air off sea and cooler drier air downwards
- as storm moves collects more water and wind speed increase
- takes hours to become cyclone of an eye, low pressure surrounded by high winds and storm
