Formation Of A Tropical Cyclone
Tropical cyclones are intense storms that develop through three interconnected stages: formation, maturity, and dissipation. They require specific conditions, including warm ocean waters above 26.5 degrees Celsius and low-altitude winds, to form, while the Coriolis effect causes the rising air to spiral, creating the cyclone’s characteristic structure. As the cyclone matures, it exhibits a significant drop in air pressure at its center, leading to stronger winds, and it can continue to grow as it moves over warm ocean waters.
