How a cyclone works and how does it form??

Question

I need this for a science project in 9 days!!!!!

HHHEEELLLPPP!!!!!!!!!!!!

Answer 1

Ok, I think it's when cold and warm air masses collide.

Answer 3

Less is known about these storms that we would like but we do have a rough idea.  Hurricanes form in tropical regions where there is warm water (at least 80 degrees Fahrenheit / 27 degrees Celsius), moist air, and converging equatorial winds. Most Atlantic hurricanes begin off the west coast of Africa, starting as thunderstorms that move out over the warm, tropical ocean waters.  

If the water is warm enough, the wind is converging, and the pressure from high altitude and low differs greatly, a hurricane can form.   The warm air near the water will pick the water up and turn into clouds, the high pressure from above will then be forced down to the surface (due to the pressure differences) and it will warm and collect water.  This cycle continues and the storm gets bigger.  The reason a storm will die when it hits land is that it loses its source of water.

Factors such as global warming will increase the frequency and intensity of hurricanes.  As the water warms it becomes easier for the hurricane to lift and use in its clouds, the warmer the water the bigger the storm.   To fully understand a hurricane we'll need to look into the water cycle and pressure systems.

Hope this helped.

Cyclones are caused by a variety of things.    Sometimes tornadoes are called cyclones but they are very small scale in comparision to the tropical and mid latitude types.

Remember cyclonic.   That means the air is rotating the opposite direction of a clock.   (low pressure)  

There are also mid-latitude storms.  These occur from 30-60 degrees and usually are associated with fronts.   Let's say you have an area of low pressure and that area actually becomes closed off.    Look at a surface chart and you will see on many ocassions,  a cold front that has a kink in it.   That signifies the storm has slowed and quite possibly a low is developing on the front.

Usually strong winds (jets) overshoot the top of an area of lower pressure it becomes one of those 'L's' you see on a chart,   with the isobar cut off into pretty much a circle all by itself.

Simiarily you have an area of low pressure that moves off the African coast and the pressure contours show what looks to be an inverted 'V'.   That would be the first stages a tropical wave.    From there,  if it has the necessary ingredients to develop,  a low will form.    

Put simply,  a cyclone needs more than just a few surface features for it to develop.   It needs contrasting wind fields, moisture and cold air aloft.   The more intense these characteristics,   the stronger the cyclone.  And in the case of tropical weather,  tropical storms and hurricanes.

Hurricanes are cyclones and Atlantic based.   Typhoons are Pacific storms and affect places like China,  Japan and the Philippines.    In India,  they are called Cyclones.. lol

Are you really confused yet?    If you need further help,  let me know..
