Tropical storms are large - sometimes  3003100030 kilometres or more across. They are easy to spot on an aerial photograph - they are swirling, cloudy features with a dark  pressureeyeearcloud in the centre where there is no cloud. They rotate due to the  HadleyCoriolisGreenhouseWalker effect.

Tropical storms develop near the  land60° linepolesequator. They form when warm air rises due to the strong heating of the Earth's surface by the  SunMoonfactoriesmeteorites.

For example, Atlantic hurricanes often form off the coast of Western Africa and travel towards the  Indonesian Islands MadagascarPhilippinesCaribbean and the East coast of the United States.
