2. rotation - the earths spin (coriolis force) helps the rising air to spiral and drags in strong winds (there isnt much spin at the equator)
Back
Card 19
Front
tropical cyclone movement
Back
Card 20
Front
they move westwards because winds blow from the east around the equator, and they spin away from the equator
Back
Card 21
Front
tropical cyclones can travel 640km a day
Back
Card 22
Front
what makes a tropical cyclone intensify and dissipate
Back
Card 23
Front
dissipate when; reach land ecause they lose energy (powered by warm water), move into areas of colder water, run into other weather systems where winds are blowing in different directions
Back
Card 24
Front
1. warm sea temperature
Back
Card 25
Front
3. rapid cooling - rising air must condense quickly to generate the huge amounts of energy powering a tropical cyclone
