For a cyclone to form, certain atmospheric conditions must be in play
- First of all, sufficiently large areas of ocean with surface temperatures of above 26.5 degrees Celcius are needed. This helps to fuel the cyclone.
- The cyclone must be forming in an area with a large enough Coriolis force to initiate the rotation, and prevent filling of the central low pressure.
- There must be a pre-existing low pressure system or a slight weather disturbance. The loe pressure systems turn eventually into tropical storms, which lead onto tropical cyclones.
- Circulation of air in the upper atmosphere should support formation of a storm.
- Low vertical wind shear to support the structure of a tropical cyclone
Once this has occurred, a tropical cyclone can begin it's formation
· First , the warm heat coming from the oceans is passed into the air by process of conduction
· The air is also wet, which means the air is drawn in. The air moves from areas of high pressure to areas of low pressure, creating wind, and the rising moisture in the air will condense, creating clouds.
· Turbulence begins inside the cloud. While the pressure is dropping, the storm is growing.
· The storm is then affected by coriolis force, which cause it to spin, and this means that nothing can get into the center, creating an eye.
Once this has happened, the storm has reached it's maturity, and if the conditions needed to start a storm stop, the storm will go into a stage of decay and get weaker.
