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.
If all of the pre-conditions are met, hurricane formation then becomes possible. There are several types of atmospheric disturbances that can cause a hurricane to develop. The most common mechanism to cause hurricanes to form is the monsoon trough. This is an extension of the Inter-Tropical Convergence Zone where cyclonic spin has developed.
