cyclones Flashcards
what do cyclones need in order to develop
large still warm ocean at 26.5 degrees
strong winds
Coriolis force
why do cyclones need a warm ocean to form?
they need both sources of heat and moisture
why do cyclones need wind to form
the winds draw up warm air from the oceans surface
why do cyclones need the Coriolis force to form?
the force enables the hurricane to spin
explain the formation of a cyclone
1) warm air rises leaving a space below which is filled with surrounding air causing strong winds
2) rising air brings moisture with it, therefore forms cumulonimbus clouds, which then form the eye wall
3) the coriolis force then causes the cyclone to spin
4) the cyclone moves away from its source becoming stronger as it picks up more moisture and heat
5) as the cyclone nears land it looses power due to lack of heat and moisture
