There are a number of structural characteristics common to all cyclones. A cyclone is a low-pressure area. A cyclone's center (often known in a mature tropical cyclone as the eye), is the area of lowest atmospheric pressure in the region.ropical cyclones form due to latent heat driven by significant thunderstorm activity, and are warm core. Cyclones can transition between extratropical, subtropical, and tropical phases under the right conditions.
The Coriolis force is required for a cyclone to form into a tropical cyclone or hurricane. The force causes a greater deflection of the air (right in the northern hemisphere and left in the southern) and the correct speeds for the tropical cyclone to form.
