GEOLOGY

Detailed explanation-1: -Hurricanes form from disturbances in the atmosphere over warm, tropical ocean water. They die down when they move over land or out of the tropics and into cooler latitudes. These storms are called hurricanes in the Atlantic and typhoons or tropical cyclones in other areas of the world.

Detailed explanation-2: -Hurricanes bring extreme rainfall Warm air can hold more moisture than cool air. In tropical cyclones, the air is particularly warm and can hold a tremendous amount of moisture. The moisture cools as it rises and condenses into heavy rain, often much more than a typical low pressure system .

Detailed explanation-3: -Surface atmospheric pressure in the center of a hurricane tends to be extremely low. The lowest pressure reading ever recorded for a hurricane (typhoon Tip, 1979) is 870 millibars (mb). However, most storms have an average pressure of 950 millibars.

Detailed explanation-4: -Warm ocean waters and thunderstorms fuel power-hungry hurricanes. Hurricanes form over the ocean, often beginning as a tropical wave-a low pressure area that moves through the moisture-rich tropics, possibly enhancing shower and thunderstorm activity.

Detailed explanation-5: -A hurricane is a tropical storm with winds that have reached a constant speed of 74 miles per hour or more. The eye of a storm is usually 20-30 miles wide and may extend over 400 miles. The dangers of a storm include torrential rains, high winds and storm surges.
