Formation of Cyclone Sean
Cyclone Sean developed on January 20, 2025, starting as a tropical disturbance and rapidly intensifying to Category 4. Key factors contributing to its formation included warm sea surface temperatures, a low-pressure system, and minimal vertical wind shear.

Causes of Tropical Cyclones

Warm Sea Surface Temperatures: Cyclones form in waters above 27°C.
Low-Pressure Area: A low-pressure zone is crucial for cyclone formation.
Coriolis Force: This causes the storm to rotate and organize.
Minimal Vertical Wind Shear: Stable wind conditions help the cyclone grow.

Structure of a Tropical Cyclone
