How are hurricanes first formed?

Question

Thank you.

Answer 1

mostly ones that hit the U.S. are small atmospheric disruptions that form over africa. for instance a nuke going off in kenya might cause a hurricane or massive Continental fire, but the most pathetic thing i heard was that a butterfly flapping it's wings in africa causes a hurricane! ya right!!! so what happens if someone Farts in south America??.....

Answer 2

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.  

Answer 3

  It forms over very hot water,a slight disturbance causes the air to begin rising,as it rises it starts to rotate and this is the beginning of a hurricane.

Answer 4

first u get a tropical wave that passes through low wind shear and warm waters. that makes the wave intensify into a low with a surface circulation. the low eventually intensifies to a tropical depression with low wind shear and warm waters.then it becomes a tropical storm and sometimes not all the time would strengthen to a hurricane

Answer 5

Hurricanes, like any other low pressure system, form over a baroclinic zone. The beginning of a hurricane is a tropical wave. Thunderstorms form and rotate around a center of low pressure. As the system gathers heat and moisture, it grows more powerful. More thunderstorms continue to form and eventually a tropical depression forms.

Answer 6

It starts out as a depression.
