A cyclone is formed when:
Cyclones, also known as hurricanes or typhoons depending on their location, are powerful tropical storms characterized by low-pressure centers, strong winds, and heavy rainfall. These storms form over warm ocean waters near the equator and typically occur in regions with sea surface temperatures of at least 26.5 degrees Celsius (79.7 degrees Fahrenheit).
The formation of a cyclone involves several key factors:
Once formed, cyclones can persist and intensify as long as they remain over warm ocean waters and are not disrupted by factors such as wind shear or interaction with land. They may gradually weaken as they move over cooler waters or encounter unfavorable atmospheric conditions. Cyclones can cause widespread destruction and pose significant threats to coastal communities through storm surge, high winds, heavy rainfall, and flooding.
