cyclone and tornado questions?
ok… my science teacher is pretty dumb.
i have been asked to do my homework with out the needed text book..
i really need the answers to these questions URGENTLY!!!!! ASAP!
1. at what time of the year is the risk of cyclones greatest. why?
2. some of the strongest north-west cyclones go almost unnoticed by the world outside the state, while significantly weaker tropical storms in other places such as florida or japan get much more news coverage. why is this?
3.why do cyclones always form over oceans?
4.how are cyclones different from tornadoes?
5.when and where do tornadoes occur in western australia?
6. most global warming models predidct that weather events in W.A will become more extreme. suggest what this will mean for cyclones and tornadoes.
if you could help me answer these questions i would be eternally greatful.
the work is very hard for me seeing as i am in year 9 and this is year 10 work.
the teacher has not even covered this chapter yet!!
any info that could help me is also appreciated if you feel uncomfortable giving away answers.
thanks!

cyclones are driven by warm sea surface temperatures and cooler air. Since I have no idea where you are talking about, i would guess in the late summer and autumn. When the warm air over the ocean rises cool air from the surrounding areas moves inward to replace it. Then Coriolis forces cause the air to move in a circular fashion, and a cyclone is born.
