Cyclone

• A cyclone is a meteorological term used to describe a weather phenomenon characterized by the circulation of winds around a low-pressure center.
• Cyclones can take various forms and are known by different names depending on their location and intensity.
• The main types of cyclones are tropical cyclones, extratropical cyclones, and tornadoes. 

The characteristics of a cyclone include:

I. Air Convergence & Circular Air Motion

• Cyclones are associated with the convergence of air masses.
• Cyclones exhibit circular or cyclonic air motion, where air flows in a counterclockwise direction in the Northern Hemisphere and a clockwise direction in the Southern Hemisphere around the center of low pressure.

II. Upliftment of Air:

• Cyclones involve the upliftment of warm, moist air, which leads to the formation of clouds and precipitation.

III. Centripetal Air Flow:

• Cyclones are characterized by inward, centripetal air flow toward the low-pressure center instead of centrifugal flow.
