The eye , eyewall and surrounding rainbands that are characteristics of tropical cyclones are clearly visible in this view from space. A tropical cyclone is a storm system characterized by a large low-pressure center and numerous thunderstorms that produce strong winds and heavy rain. Tropical cyclones strengthen when water evaporated from the ocean is released as the saturated air rises, resulting in condensation of water vapor 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 . The characteristic that separates tropical cyclones from other cyclonic systems is that any height in the atmosphere, the center of a tropical cyclone will be warmer than its surrounds; a phenomenon called " warm core " storm systems.

What can we do to reduce the consequences and costs of severe weather events? IN DEPTH: Was Hurricane Katrina a product of global warming? What is a hurricane? A hurricane is an intense tropical storm. Tropical storms form over warm tropical oceans during periods when local sea surface temperatures are above 26.5 °C (80 °F). Under these conditions, evaporation from the ocean surface generates very high humidity in the atmosphere, which in turn generates thunderstorms. A tropical storm forms when a system of powerful thunderstorms converges and begins to rotate in the atmosphere, forming a vortex known as a tropical depression . Heat from the ocean surface is drawn up through the center of the vortex and released to the atmosphere as water vapor condenses to form rain around the perimeter of the vortex. Energy from ocean heat also generates high winds. The more heat available in the surface water, the more potential there is to generate heavy rain and high wind. If wind speeds exceed 35 mph, the National Hurricane Center deems the system a

are severe tropical storms that form in the southern Atlantic Ocean, Caribbean Sea, Gulf of Mexico, and in the eastern Pacific Ocean. Hurricanes gather heat and energy through contact with warm ocean waters. Evaporation from the seawater increases their power. Hurricanes rotate in a counter-clockwise direction around an "eye." Hurricanes have winds at least 74 miles per hour. When they come onto land, the heavy rain, strong winds and heavy waves can damage buildings, trees and cars. The heavy waves are called a storm surge. Storm surges are very dangerous and a major reason why you MUST stay away from the ocean during a hurricane warning or hurricane.

(Photo courtesy NOAA / National Climatic Data Center) TOPICS: how do hurricanes form? hurricane safety hurricane links How do hurricanes form? Hurricanes are mind-boggling in their size and strength. Modern technology lets us see how big hurricanes are and track them through satellite imagery, while storm-penetrating aircraft measure their strength, in terms of wind speeds and atmospheric pressure. That technology gives us detailed warnings that people a century ago never had. Hurricanes usually form in the tropical zones north and south of the equator, where warm waters offer ample fuel for storm formation. That's where you see convection , where warm air rises and forms clusters of thunderstorms. The Coriolis effect, created by the Earth's spinning motion, may cause this cluster of storms to rotate (counter-clockwise above the equator, or clockwise below), but the system has to be a few hundred miles from the equator for the Coriolis force to exert an effect. If the system becomes organized and strong enough, with sustained winds of 39 miles per hour, it becomes a tropical storm. At 74 miles per hour or more, it becomes a hurricane. A hurricane can be hundreds of miles across. It's like a big engine, with upper-level winds acting as a vent, pulling the rising warm air away from the storm. Rain bands spiral around the center of the system. Air sinks in the clear center, or

Graphic by: Dan Bramer Interact with Atlantic hurricanes from 1950-2007!! Hurricanes are cyclones that develop over the warm tropical oceans and have sustained winds in excess of 64 knots (74 miles/hour). These storms are capable of producing dangerous winds, torrential rains and flooding, all of which may result in tremendous property damage and loss of life in coastal populations. One memorable storm was Hurricane Andrew (pictured above), which was responsible for at least 50 deaths and more than $30 billion in property damage. The purpose of this module is to introduce hurricanes and their associated features, to show where hurricanes develop, and to explain the atmospheric conditions necessary for hurricane development. The Hurricane module has been organized into the following sections: Sections Last Update: 09/16/99 Definition and Growth Defines a hurricane and shows the regions and mechanics of hurricane development. Stages of Development The different stages of development from depression to hurricane. Structure of a Hurricane Discusses the structure of different parts of hurricanes.

Hurricanes by Rachel Rusch and Janira Vazquez, grade 8 Hurricanes are very destructive storms of nature. They consist of very powerful and deadly winds that measure from 200-300 miles in diameter. Near the center or the eye of the storm, winds measure up to 74 miles per hour or more. The heavy winds cause large waves which contribute to devastating floods. Over 90% of deaths in hurricanes occur from drowning. Development Hurricanes develop from easterly waves in long narrow regions of low pressure from trade winds. There are different levels of intensity before a storm develops into a hurricane. It develops from easterly waves to tropical depressions, to tropical storms, then into a hurricane. They form in the North Pacific and Atlantic Oceans over warm water in areas of low pressure; usually in the hurricane season of June to November. However, most storms occur in September. There are usually about 6-8 hurricanes each year. Effects Hurricanes in the United states affect mostly the Atlantic ocean and the Gulf of Mexico. They move around the eye in a counterclockwise direction, and usually move west to gain power. Most affect the east coast greatly. Several storms have caused devastating results here in Florida. Including Hurricane Andrew . It was one of the most intense storms in the 1900's history of the United states.

Do you know the basic ingredients for weather? Check here How Hurricanes Work Hurricanes are huge storms! They can be up to 600 miles across and have strong winds spiraling inward and upward at speeds of 75 to 200 mph. Each hurricane lasts for over a week, moving 10-20 miles per hour over the open ocean. With warm air at its center, a hurricane is different from extratropical cyclones, which are the most common type of storm in the United States. The center of the storm is the calmest part. It is called the eye and has only light winds and fair weather. The low level storm winds blow counterclockwise around the eye in the Northern Hemisphere (clockwise in the Southern Hemisphere). Above 9 km, winds spiral outwards and clockwise in the Northern Hemisphere. A storm goes through a series of stages before being classified as a hurricane. Tropical Disturbance Thunderstorms with light cyclonic circulation Tropical Depression Wind speeds between 20 and 34 knots (23-39 mi/hr) Tropical Storm Wind speeds between 35 and 64 knots (40-73 mi/hr) Hurricane Wind speed greater than 64 knots (74 mi/hr) Play the Hurricane Name Game!

What are Hurricanes? Most people associate twisters with tornadoes, but in fact tropical twisters come from hurricanes. Hurricanes are what scientists call "strong Tropical Cyclones". They are formed when large areas of the ocean become heated, and the air pressure over that area drops. This causes thunderstorms and strong surface winds. Cyclones develop over tropical or sub-tropical waters (for example, in the Atlantic off the coast of Africa, or in the Pacific). As they travel long distances gathering energy from the ocean, they are likely to be classified as strong Tropical Cyclones. When the winds of a tropical storm reach 74 mph, then the storm is classified as a hurricane. How are Hurricanes Created? Why do Hurricanes Move? How Dangerous are They? One of NASA's most important missions is to develop an understanding of the total Earth system and study the effects of natural and human- induced changes on the global environment. To achieve these goals, NASA has developed satellites and ground programs which study and monitor hurricanes and other climatic events. ESE Kids Only Home ESE Homepage NASA Air ...

Hurricanes Hurricanes are tropical cyclones with winds that exceed 64 knots (74 mi/hr) and circulate counter-clockwise about their centers in the Northern Hemisphere (clockwise in the Southern Hemisphere). Image by: the GOES Project Hurricanes are formed from simple complexes of thunderstorms Image by: OSDPD Related to having warm ocean water, high relative humidities in the lower and middle troposphere are also required for hurricane development. These high humidities reduce the amount of evaporation in clouds and maximizes the latent heat released because there is more precipitation . The concentration of latent heat is critical to driving the system. The vertical wind shear in a tropical cyclone's environment is also important. Wind shear is defined as the amount of change in the wind's direction or speed with increasing altitude. The video below shows how wind shear plays a role in hurricane formation. When the wind shear is weak, the storms that are part of the cyclone grow vertically, and the latent heat from condensation is released into the air directly above the storm, aiding in development. When there is stronger wind shear, this means that the storms become more slanted and the latent heat release is dispersed over a much larger area.
