Tropical cyclone is the most commonly observed form of cyclone. This severe weather condition is prevalent on warm oceans. Tropical cyclone comes with powerful current of air, heavy rainfall and severe thunderstorms. Tropical cyclones fall under the purview of warm core system of storms. Tropical cyclones are developed by a special type of heat mechanism, which is different from all other storm systems.

Creation of Tropical Cyclone

Heat mechanism causes upward movement of warm air. As the moist air moves up it comes in contact with the cold air in the upper level of atmosphere and gets condensed. A powerful low-pressure cell is an essential factor for tropical cyclone. A revolving draft with a strong inward current leads to tropical cyclone.

Types of Tropical Cyclone

Different types of tropical cyclones are observed all over the world. Based on its location and severity, tropical cyclone is classified as typhoon, tropical storm, cyclonic storm, tropical depression and hurricane. If the velocity of storm wind is not more than 60 kilometers per hour, it is termed as tropical depression. Tropical storms come with a speed of 60 to 110 kilometers pre hour. Wind speed associated with tropical cyclones must be more than 100 kilometers per hour. Tropical cyclones, which break out in the eastern part of North Pacific and northern Atlantic regions are popularly known as hurricanes. The same when occurs in the western part of North Pacific, it is termed as typhoon.

Features of Tropical Cyclone

The revolving draft that develops during tropical cyclone can be variable size ranging from 200 to 2000 kilometers in diameter. Abnormally high pressure gradient, strong wind and heated center are some of the basic features of tropical cyclone.
