Question

How can a hurricane Form?

Answer 1

A tropical cyclone is a storm system characterized by a low pressure center and numerous thunderstorms that produce strong winds and flooding rain. A tropical cyclone feeds on heat released when moist air rises, resulting in condensation of water vapour contained in the moist air. They are fueled by a different heat mechanism than other cyclonic windstorms such as nor'easters, European windstorms, and polar lows, leading to their classification as "warm core" storm systems.

The term "tropical" refers to both the geographic origin of these systems, which form almost exclusively in tropical regions of the globe, and their formation in Maritime Tropical air masses. The term "cyclone" refers to such storms' cyclonic nature, with counterclockwise rotation in the Northern Hemisphere and clockwise rotation in the Southern Hemisphere. Depending on their location and strength, tropical cyclones are referred to by other names, such as hurricane, typhoon, tropical storm, cyclonic storm, tropical depression and simply cyclone.

Researchers have learned that most hurricanes form after the ocean water warms up past 80 degrees F (27C).Thats why hurricanes north of the equator happen between June and November. Warm water evaporates more quickly than cold water so the air above has high amounts of water vapor that condenses to form clouds droplets gives off heat into the air. This heat is added to the tropical air that is already warm. This causes a large pulse of heat to rise high into the atmosphere. If the winds at the surface and high in the atmosphere travel in the same direction, it causes the warm air to concentrate in one spot. The combination of heat and moisture forms bands of spiraling thunderstorms. As they spin, they blow in ward toward the center. The rain is very heavy in these bands. between bands it is either raining lightly or not at all. the most violent band with the heaviest rain is the eye wall, which surrounds the eye or center of the hurricane . The eye is normally about 15 miles in diameter. All the updrafts caused by the thunderstorms spread out when they hit the stratosphere to form a nearly continuous cloud shield above the storm. By this time the barometric pressure in the middle of the mass has dropped, causing the wind to increase. Wind from the thunderstorms whips the ocean water into a spray. This in turn increases evaporation form the ocean adding more water capo into the air, which adds more heat as it condenses. This results in the air pressure dropping even more making the winds blow even harder. Within a few days the heat moisture pressure and wind whip each other in to a full blown hurricane.

there is a lot of info on that, but way too much to type here just read this article
