1. - Cyclones start over warm sea waters, the temperature needs to be 26.5 degrees or hotter.
- Cyclones occur 5 to 20o north or south of the equator.
2. - Moisture is added to the air by the evaporation of sea water and starts spinning in a clockwise direction because
of the earths rotation (Coriolis effect).
- This hot air rises and more hot air is sucked beneath it.
- Air currants force the air to spin faster and create a vacuum effect forcing more and more hot air
in and pushing the spiraling colum of air Higher into the atmosphere.
-Thunder storms also heat the air futher and allow more hot air to be sucked inside.
- The clouds on the wall of a cyclone are usualy cumulonimbus.
