An introduction to the way a hurricane begins
What is a hurricane
Several of the hurricanes have caused catastrophic damage not only to coastal cities and towns, but inland communities as well. Past and Present Tropical Tracks: Click to see the tracks of this year's storms. This is the most dangerous part of the hurricane and where the highest speed winds are. The second, more widespread and common and much more damaging, is from inland flooding, which puts at risk all valleys along with their structures and critical transportation facilities, such as roads and bridges. Call Us - How do hurricanes form? This is due to the rotation of the Earth called the Coriolis effect. The whole system of clouds and wind spins and grows, fed by the ocean's heat and water evaporating from the surface. As this air sinks towards the surface, it is compressed by the weight of the air above it and warms. Surface pressures fall when water vapor condenses in rising air and releases energy, or latent heat, into areas within the tropical disturbance. Hurricane A tropical cyclone with sustained winds of at least 74 mph. Hurricanes are enormous heat engines that deliver energy on a staggering scale. The most vulnerable coastal zones are those with the highest historical frequencies of landfalls. Tropical storms occur in several of the world's oceans, and except for their names, they are essentially the same type of storm. Hurricane Harvey , which dropped a record-breaking The structure of a hurricane Where do tropical cyclones occur?
Essays may be lightly modified for readability or to protect the anonymity of contributors, but we do not edit essay examples prior to publication. However, they often move far inland, dumping many inches of rain and causing lots of wind damage before they die out completely.

The hurricane season was one of the most active on record, with 22 major hurricanes in the Northern Hemisphere in under three months, and also saw seriously devastating Atlantic storms. From to , tropical cyclones of the North Atlantic Ocean were identified by the phonetic alphabet Able-Baker-Charlie-etc. The strongest Atlantic storm was Wilma in , with winds of miles km an hour. Find out what experts are predicting for the hurricane season and take part in our poll. Hurricanes typically form between 5 to 15 degrees latitude north and south of the equator. Tropical Storm A tropical cyclone with maximum sustained wind speeds that range from 39 to 73 mph. As the warmed, moist air rises and cools off, the water in the air forms clouds. This is called hurricane season. The most vulnerable coastal zones are those with the highest historical frequencies of landfalls. At the surface, hurricanes can diminish rather quickly given the right conditions. In the western Pacific and China Sea area, hurricanes are known as typhoons, from the Cantonese tai-fung, meaning great wind. Figure shows the relationship between wind speed, expressed in the codes in terms of meters per second rather than kilometers or miles per hour, and general property damage. How many hurricanes will form in ? The rest of the world eventually caught on, and naming rights now go by the World Meteorological Organization, which uses different sets of names depending on the part of the world the storm is in.
So the first storm of the year will always have a name that starts with the letter "A. As the air rises, it cools, and water vapor condenses into clouds.
Below is a satellite image of Hurricane Mitch back in October Topography plays an important role: wind speed is decreased at low elevations by physical obstacles and in sheltered areas, while it is increased over exposed hill crests Davenport, ; see Figure The second, more widespread and common and much more damaging, is from inland flooding, which puts at risk all valleys along with their structures and critical transportation facilities, such as roads and bridges.
The magnitude of the surge at a specific site is also a function of the radius of the maximum hurricane winds, the speed of the system's approach, and the foreshore bathymetry. Step 4.
Locations of tropical cyclones throughout the world When do hurricanes occur? The diameter of the hurricane is measured from one side to the other. This is called hurricane season. Tropical Depression An organized area of low pressure in which sustained winds are 38 mph or less.
Tropical cyclones go by different names in different places. This allows our team to focus on improving the library and adding new essays.
