why do hurricanes form in the tropics?

Answer 1

Heat=energy. More heat in the tropics, right? Lots of energy= big storm, like tropical storms and hurricanes.

Answer 2

Warm water,moisture and wind pattern near the ocean surface that spirals inward are the three minimum required conditions for the formation of hurricanes.They gather heat and energy through contact with warm ocean water.The sea surface temperature shoud be about 28 degrees celcious.These favourable conditions are available only in tropics.They usually form between latitudes 10 degrees and 30 degrees North and South along the Inter Tropical Convergence Zone which is a narrow zone in which air masses originating in the two hemispheres converge.Its mean position is slightly north of equator.These converging tropical airmasses are suffiently warm and humid and have favourable lapse rates up to great heights.So these favourable conditions are responsible for the formation of these hurricanes in the tropics.

Answer 3

Because of the warm tropic air!

Answer 4

A tropical cyclone is a warm-core, low pressure system without any "front" attached, that develops over the tropical or subtropical waters, and has an organized circulation. Depending upon location, tropical cyclones have different names around the world. In the:
Atlantic/Eastern Pacific Oceans - hurricanes
Western Pacific - typhoons
Indian Ocean - cyclones
Regardless of what they are called, there are several favorable environmental conditions that must be in place before a tropical cyclone can form. They are:
Warm ocean waters (at least 80°F / 27°C) throughout a depth of about 150 ft (46 m).
An atmosphere which cools fast enough with height such that it is potentially unstable to moist convection.
Relatively moist air near the mid-level of the troposphere (16,000 ft / 4,900 m).
Generally a minimum distance of at least 300 miles (480 km) from the equator.
A pre-existing near-surface disturbance.
Low values (less than about 23 mph / 37 km/h) of vertical wind shear between the surface and the upper troposphere. Vertical wind shear is the change in wind speed with height.
Tropical Cyclone Formation Basin
Given that sea surface temperatures need to be at least 80°F (27°C) for tropical cyclones form, it is natural that they form near the equator. However, with only the rarest of occasions, these storms do not form within 5° latitude of the equator. This is due to the lack of sufficient Coriolis Force, the force that causes the cyclone to spin. However, tropical cyclones form in seven regions around the world.
One rare exception to the lack of tropical cyclones near the equator was Typhoon Vamei which former near Singapore on December 27, 2001. Since tropical cyclone observations started in 1886 in the North Atlantic and 1945 in the western North Pacific, the previous recorded lowest latitude for a tropical cyclone was 3.3°N for Typhoon Sarah in 1956. With its circulation center at 1.5°N Typhoon Vamei's circulation was on both sides of the equator. U.S. Naval ships reported maximum sustained surface wind of 87 mph and gust wind of up to 120 mph.
The seedlings of tropical cyclones, called "disturbances", can come from:
Easterly Waves: Also called tropical waves, this is an inverted trough of low pressure moving generally westward in the tropical easterlies. A trough is defined as a region of relative low pressure. The majority of tropical cyclones form from easterly waves.
West African Disturbance Line (WADL): This is a line of convection (similar to a squall line) which forms over West Africa and moves into the Atlantic Ocean. WADL's usually move faster than tropical waves.
TUTT: A TUTT (Tropical Upper Tropospheric Trough) is a trough, or cold core low in the upper atmosphere, which produces convection. On occasion, one of these develops into a warm-core tropical cyclone.
Old Frontal Boundary: Remnants of a polar front can become lines of convection and occasionally generate a tropical cyclone. In the Atlantic Ocean storms, this will occur early or late in the hurricane season in the Gulf of Mexico or Caribbean Sea.
Once a disturbance forms and sustained convection develops, it can become more organized under certain conditions. If the disturbance moves or stays over warm water (at least 80°F), and upper level winds remain weak, the disturbance can become more organized, forming a depression.

The warm water is one of the most important keys as it is water that powers the tropical cyclone (see image above right). As water vapor (water in the gaseous state) rises, it cools. This cooling causes the water vapor to condense into a liquid we see as clouds. In the process of condensation, heat is released. This heat warms the atmosphere making the air lighter still which then continues to rise into the atmosphere. As it does, more air moves in near the surface to take its place which is the strong wind we feel from these storms.

Therefore, once the eye of the storm moves over land will begin to weaken rapidly, not because of friction, but because the storm lacks the moisture and heat sources that the ocean provided. This depletion of moisture and heat hurts the tropical cyclone's ability to produce thunderstorms near the storm center. Without this convection, the storm rapidly diminishes.
There are many suggestions for the mitigation of tropical cyclones such as "seeding" storms with chemicals to decrease their intensity, dropping water absorbing material into the storm to soak-up some of the moisture, to even using nuclear weapons to disrupt their circulation thereby decreasing their intensity. Read about tropical cyclone myths. While well meaning, the ones making the suggestions vastly underestimate the amount of energy generated and released by tropical cyclones.

Even if we could disrupt these storms, it would not be advisable. Since tropical cyclones help regulate the earth's temperature, any decrease in tropical cyclone intensity means the oceans retain more heat. Over time, the build-up of heat could possible enhance subsequent storms and lead to more numerous and/or stronger events.

There has also been much discussion about the abnormally high number of storms for the 2005 Atlantic basin. Compared to the age of the earth, our knowledge about tropical cyclone history is only very recent. Only since the advent of satellite imagey in the 1960's do we have any real ability to count, track and observe these systems across the vast oceans. Therefore, we will never know the actual record number of tropical cyclones in the Atlantic Oceans.

Answer 5

I believe it has something to do with the water being hot .. Im not too sure of the specifics

Answer 6

because wherever there are seas hurricans usally hit there
