Question 14

how does a tropical storm form

Answer 14

1. air is heated above the surface of warm tropical oceans . The wrm air rises rapidly under low pressure conditions .
2. The rising air draws up more air and large volumes of moisture from the ocean , causing strong winds.
3. The Coriolis effect causes the air to spin upwards around a calm central eye of the storm .
4. As the ir rises , it cools and condenses to from lalrge , towering cumulonimnus clouds , which generate torrential rainfll . The heat given off when the air cools powers the tropical storm .
5. Cold air sinks in the eye , thereofre there is no cloud , so it is drier and much calmer .
6. Te tropical storm travels across the ocean in the prevailing wind .
7. When the tropical storm meets land it is no longer fuelled by the source of moisture and heat from the ocean so it looses it power and weakens .
