Where are hurricanes formed?

Answer 1

In Tropical Oceans, where the surface temperature is obove 80 degrees

Answer 2

The three major requirements for the formation of a hurricane/tropical cyclone/typhoon are:
1. a pre-existing low pressure system. This is the equatorial trough (also called the monsoon trough or the intertropical convergence zone). The trough moves north and south of the equator with the apparent movement of the sun. The trough provides the unstable air so that any air that starts rising will continue to do so through the troposphere.
2. further than 5° from the equator. The Coriolis effect, the turning of objects moving across the surfce of the Earth due to the rotation of the planet about its axis, is proportional to the sine of the latitude. This means it is zero at the equator. It is not until you are more than 5° from the equator that Coriolis is strong enough to get the system turning.
3. A sea surface temperature in excess of 26°C. There needs to be a lot of evaporation from the warm ocean to provide the latent heat of condensation and freezing in the clouds of the system to fuel the hurricane. It is this last requirement that makes hurricanes in the south Atlantic so rare. There are no warm shallow seas where the surface temperature can get above 26°C for long enough to get a hurricane going.

Answer 3

Hurricanes gather their immense power from the warm waters of the Atlantic Ocean. From there, evaporating seawater fuels their girth as they churn their way over land and sea, leaving death and destruction in their paths. Find out in depth how they form, how they're forecasted and how they kill.

Hurricanes are violent storms which begin in the tropics. They are the most powerful of all weather systems. Different parts of the world call hurricanes by different names.

Hurricanes form over the warm tropical water in ocean and die down when they move over land. Meteorologists try to forecast where and when the center of the storm, the eye, will reach land in order to warn people about the damage caused by the strong winds, heavy rain, and storm surge.

Hurricanes have been given alternating male and female names since 1979. These names change every year. Hurricanes may form anytime during the year, but they are most likely to form between June 1st and November 30th; this is hurricane season.

Hurricanes can occur throughout the year, but the hurricane season usually lasts from the beginning of June to the end of November, with the peak months being August and October. There is an average of 3.5 tropical storms, yearly, with a lifespan of 1 to 30 days. Within that time, a hurricane can do more destruction than imaginable. Forming a hurricane is a complicated process. There are many steps on the ladder of a full hurricane.Hurricanes must be over water to form. They thrive when over tropically heated waters and climates, usually in tropical zones north and south of the equator, although we, on the west coast, are not in danger, for more than one reason. First, the water is too cold and second, we are not near enough to the equator to be endangered. The temperature of the water must at least be 81 degrees F. The reason any hurricane thrives over heated waters, is because the water is a form of energy, and the heat from the water gives the storm strength to get larger and more destructive. Generally, hurricanes move about 10 mph, but as they get closer to the North Pole their speed increases (London, Mark.)

For a hurricane to begin there must be a cycle in the ocean's warm air. The air starts to evaporate rapidly and forms clouds and rain. The high-pressured air is then sucked into the center of the storm and becomes a hurricane, it must first go through a couple of phases. When winds become 39 mph it becomes a tropical storm, which can do just as much damage as a hurricane. When the wind's speed reaches 74 mph or more, it is a hurricane. (Kidler, Chrish). There isn't a general size for a hurricane. They can be very small and compact or they can be extremely large and spread out. For example, hurricane Floyd, 1998, spread from the Caribbean and New England! Hurricanes can stretch to 700 miles across, and the "eye" can reach anywhere from 5 to 100 miles in diameter. The shape of the actual hurricane is symmetric and circular. (Davis, Lee)

Answer 4

Hurricanes (and other tropical cyclones, such as typhoons) form when atmospheric instability occurs over warm water. This happens most frequently over tropical water, but it can occur over warm water outside of the tropics. Under the right conditions, a low pressure system at sea level begins evaporating warm water from the ocean, deriving energy from the latent heat of the water vapor. This drives a massive heat engine that results in the strongest storms known on Earth.

Hurricane formation regions include the Gulf of Mexico, the west coast of Africa (especially August through October), and the west coast of Mexico. Typhoons form mainly in the western Pacific Ocean, and other tropical cyclones form in the southern Pacific Ocean or the Indian Ocean. Tropical cyclone formation in the southern Atlantic Ocean is extremely rare, and the formation of the informally named Cyclone Caterina there in 2004 is thought to be a once-in-a-lifetime occurence.

Answer 5

Good question. Storms that can affect the US generally orginate off the coast of Africa where the surface wind patterns favor the initial cyclonic circulation needed to get a storm organized. Here is how that works. So-called monsoonal winds to the south of the trade winds (general easterlies) are southerly or south-westerly winds being drawn into the hot continent of Africa. This circulation gives rise to cloud formation and the release of latent heat of condensation which fires up the storm's engine even more. But, and this is very important, anywhere you find a monsoonal trough structure in the winds (south-westerly to easterly or south-easterly as you go north from the equator) together with a suitable sea surface temperature of 28 C or higher, you will have a tropical cyclone genesis area.

Answer 6

Hurricanes and Tropical storms will form over any tropical ocean. This includes the atlantic ocean, the pacific, and the indian ocean. Here they are called hurricanes, in the western pacific (Asia) they are called typhoons, and over the indian ocean they are called cyclones.

Hurricanes can from in any of these oceans as long as the surface temp of the water is 80°F or higher, and it remains this warm for about 150 to 200 feet deep. Other factors tha are important would be cooling aloft, high humidity, and low wind sheer. They originate on the eastern side of oceans, but move west, intensifying as they move.

Winds off of the African coast can spawn the atlantic storms, but not always. Winds from Mexico can spawn the eastern pacific storms, but also not always the case.

Hurricanes occur between July and October in the Atlantic, eastern Pacific and the western Pacific, north of the equator. South of the equator, off Australia and in the Indian Ocean, they occur between November and March.

Answer 7

They are formed from tropical storms where the surface temperarture is above 80 degrees Farenheit.
Some tropical storms form off the west coast of the continent of Africa and then increase into hurricanes as they travel west along the "conveyor belt" of ocean and wind currents.

Answer 8

Hurricanes form over the warm ocean waters. Mostly during the summer.

Answer 9

Off the coast of Africa

Answer 10

African coast go into oceans and become hurricanes.
