In the US, the “storm of the century” Milton has started to show its impact. Following the start of the Atlantic hurricane season predicted to be “quite active” this year, the US, which has not yet recovered from the damage caused by Helene and is now preparing to face a major challenge with Milton, has been affected by destructive hurricanes in the past as well. So, what is a hurricane and why does it occur? A hurricane is a large storm characterized by strong winds and heavy rainfall, usually forming in tropical regions. Hurricanes are typically classified as tropical cyclones, typhoons, and tornadoes. Tropical cyclones are large storms that form over oceans; typhoons are the name given to such storms in Asia. Tornadoes are smaller but more destructive cyclonic winds. Hurricanes are generally large storms that form in tropical regions and occur when the following conditions come together: Warm Water: The water temperature on the ocean surface must be 26°C (approximately 79°F) or higher. This temperature increase enhances evaporation, providing energy. High Humidity: Evaporation of warm water increases humidity in the air. High humidity supports hurricane formation. Low Pressure: A low-pressure area is required for air to rise, causing air to move outward from the center. Rotational Motion: The Coriolis effect, due to the Earth’s rotation, causes wind to rotate in a certain direction. This strengthens the hurricane’s rotational motion. Atmospheric Conditions: Upper atmospheric air currents can influence the development and direction of a hurricane.
