Hurricanes a tropical cyclone with winds > 64 knots
Hurricanes are formed from simple complexes of thunderstorms. However, these thunderstorms can only grow to hurricane strength with cooperation from both the ocean and the atmosphere.

A tropical cyclone is the common name given for hurricanes, tropical storms, and tropical depressions together. The benefit of understanding tropical cyclone origination is a better understanding of later development.
hurricanes: tropical storms with winds exceeding 74 mph originating over the North Atlantic and North Pacific oceans near high humidity and light winds.
Hurricanes Severe tropical storms whose winds exceed 74 mph. Hurricanes originate over the tropical and subtropical North Atlantic and North Pacific oceans, where there is high humidity and light wind.

Hurricanes occur along the western boundaries of the Atlantic and Pacific oceans, in both northern and southern hemispheres, except for the South Atlantic, which has no hurricanes.
>> Hurricanes, or tropical cyclones, form in an environment of little or no vertical wind shear.
In well-developed hurricanes, the radius of maximum winds is generally found at the inner edge of the eyewall.
is as much as 50 miles or even more before the first ragged rain echoes of the hurricane's bands and is usually about 100 to 200 miles ahead of the eye, but it has been observed to be as much as 500 miles ahead of the eye in the largest hurricanes.
When the NAO is in its negative phase (-NAO), the Tropical Atlantic and Gulf coast have increased number of strong hurricanes; northern Europe is drier, and Turkey along with other Mediterranean countries has increased precipitation.
They are issued for all tropical storms and hurricanes in the Atlantic (which includes the Caribbean Sea and the Gulf of Mexico) and central Pacific.
Concentric RingsThese are common in the most intense hurricanes. They usually mark the end the period of intensification. These hurricanes then maintain quasi-constant intensity or weaken.
This term encompasses tropical depressions, tropical storms, hurricanes, and typhoons.
Tornadoes are not named like hurricanes are, but the strong or deadly tornadoes are usually remembered for the town or location that they affected.
Hurricanes are rated on a Saffir-Simpson scale measures hurricane wind speeds based on structural effects. F1 is for 74-95 MPH winds, F2 is for 96-112 MPH, F3 is for 111-130 MPH, F4 is for 131-155 MPH, and F5 is over 155 MPH.
Cyclones, Typhoons and Hurricanes The recent floods in Mozambique and Madagascar are the result of a very active tropical storm season in the Indian Ocean this year.
Coriolis Effect - In synoptic scale weather systems (hurricanes and large mid-latitude storms), the Coriolis force causes the air to rotate around a low pressure center in a cyclonic direction.
Since hurricanes do not always form over the same locations, the geographical location of the model's forecast varies from run to run. This is called a relocatable model.
SLOSH (Sea, lake and overland surges from hurricanes)
A computerized model that is able to estimate the overland tidal surge heights and winds that result from hypothetical hurricanes with selected characteristics in pressure, size, forward speed, ...

The portion of the year having a relatively high indidence of hurricanes. The hurricane season in the Atlantic, Caribbean, and Gulf of Mexico runs from June 1 to November 30.
Hurricane Season: The portion of the year having a relatively high incidence of hurricanes. The hurricane season in the Atlantic, Caribbean, and Gulf of Mexico runs from June 1 to November 30.
These are common in the most intense hurricanes. They usually mark the end the period of intensification. These hurricanes then maintain quasi-constant intensity or weaken. When the inner eye is completely dissipated, more intensification may occur.
Usually around 300 miles across, hurricanes are 1,000-5,000 times larger than tornadoes. Hurricanes are known by different names around the world. In Japan they are Typhoons, while Australians call them Willy-Willys.
Definitions of terms used to describe tropical cyclones, including hurricanes
Easterly Wave: A wavelike disturbance in the tropical easterly winds that usually moves from east to west. Such waves can grow into tropical depressions. ...
HURRICANE SEASON: The part of the year having a relatively high incidence of hurricanes. In the Atlantic, Caribbean, Gulf of Mexico, and Central Pacific, the season is from June through November.
Saffir-Simpson scale: The system by which hurricanes are classified on a scale from 1 (minimal hurricane) to 5 (catastrophic hurricane), based on potential wind and seawater damage.

In synoptic scale weather systems (hurricanes and large mid-latitude storms), the Coriolis force causes the air to rotate around a low pressure center in a cyclonic direction.
hurricane- an extremely low-pressure, destructive weather cell of tropical origin with wind speeds in excess of 74 miles per hour (119 kilometers per hour). Hurricanes causes widespread flooding and wind damage in North America and the Caribbean.
National Hurricane Center (NHC) Agency, located in south Florida, that is responsible for forecasting tropical storms and hurricanes along the East and Gulf coasts and the eastern Pacific Ocean.

A modified radiosonde package that is dropped by parachute from an aircraft to obtain temperature, pressure, and humidity profiles of the atmosphere below flight level; often used by aircraft weather reconnaissance of hurricanes.
Tropical cyclones with sustained winds above 73 miles per hour are known as hurricanes in the North Atlantic Ocean, Caribbean Sea, Gulf of Mexico and the Eastern North Pacific (east of the date line) and cyclones in the Indian Ocean.
The name Tropical cyclone is usually used for systems in the southwest Pacific and Indian Oceans, while other names such as tropical storms, hurricanes and typhoons are used in other parts of the world.
This mode operates like normal precip mode, but utilizes VCP11 and produces an image about every 5 minutes. This mode is only used for research or for extreme weather events like hurricanes or tornadoes.
