Tropical Storms Flashcards
What is a tropical storm
A very powerful weather system characterised by strong winds that originate over tropical or subtropical waters
- they travel from east to west
- happens during late summer
How is a tropical storm formed
1) warm air rises from the ocean, as the warm air rises it leaves the area of low pressure. That space is filled with rushing air creating strong winds
2) the air that has rushed in now rises up and brings moisture. The moisture cools and condenses to form storm cloud and the eye wall
3) when the cool air descends it will from an area of calm in the centre called the eye
4) due to the winds near the equator the tropical storms starts to move from east to west .
