Quick Links and Additional Resources. In the Southern Hemisphere, the tropical cyclones originating in the southwestern Indian Ocean are more likely to hit Madagascar and countries along the east coast of Africa, while those occurring in the southeastern Indian Ocean are likely to hit the northern coast of Australia.
Tropical Disturbance An organized area of thunderstorms that usually forms in the tropics. 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.
Eventually, the RFD wraps itself around the tornado and cuts off the warm air supply, dissipating the wind funnel. Though every state experiences these funnel-shaped winds, they have tended to be most common around an area between the Rocky Mountains and Appalachian Mountains, nicknamed "tornado alley".
Coastal beach erosion is the wearing away of land, the removal of beach or dune sediments by wave action, tidal currents, wave currents, or drainage. If a hurricane does significant damage, its name is retired and replaced with another.
Call Us - How do hurricanes form? Waves are generated by storms, wind, or hurricanes and can cause coastal erosion. The same trend can be seen in the Eastern Pacific wherein most hurricanes occur in August and September. In the Western Pacific, where they are known as typhoons, they occur between July and September.
In the Western Pacific Ocean, they are called typhoons. Longer term flooding on rivers and streams can persist for several days after the storm. More than people have died in southern US states as a result of the tornadoes this week, a figure that was last surpassed inwhen people in the whole of the US died in tornadoes.
Hurricane rampage is not restricted to the coastal regions. In fact, flooding is the major threat from tropical cyclones for people living inland.
Flash flooding, defined as a rapid rise in water levels, can occur quickly due to intense rainfall. Rainfall amounts are not directly related to the strength of tropical cyclones but rather to the speed and size of the storm, as well as the geography of the area.
In the Southern Hemisphere, on the other hand, the occurrence is prominent between December and May.
Debris, such as signs, roofing material, siding and small items left outside become flying missiles during hurricanes. Hurricane Stages A low pressure trough moving generally westward with the trade winds. Basically, hurricanes are at their peak halfway through the season.
Typically, they maintain their identity for 24 hours and are accompanied by heavy rains and gusty winds. The chances of hurricanes in the South Atlantic are pretty rare; the last time one occurred here was back in Cyclone Catarina.
Click to find all the data and information about a specific hurricane by just knowing the year. For instance, the hurricane season for the North Atlantic Ocean begins on June 1 and ends on November This is a satellite animation of Hurricane Georges, which struck the Mississippi Gulf coast in Rip Currents The strong winds of a tropical cyclone can cause dangerous waves that pose a significant hazard to mariners and coastal residents and visitors.
If it is strong enough, a hurricane can continue to cause widespread destruction for a considerable time after the landfall. Also, the wind must be blowing in the same direction and at the same speed to force air upward from the ocean surface.
When and Where Do Hurricanes Occur? Wind, waves, and sea-level rise all contribute to storm-surge damage.
Supercells contain a system of rotating winds called a mesocyclone, which exists high in the atmosphere and can be several miles across. A typical tornado begins when increasing amounts of rainfall drag down a column of air known as the rear flank downdraft RFD.
This is done by the World Meteorological Organization WMOwhich has predesignated lists of hurricane names in alphabetical order for every region that is prone to hurricanes.
In the Northern Hemisphere, hurricanes occur between the months of June and November. What is coastal beach erosion?Using TRMM, meteorologists can track the more devastating hurricanes such as Mitch, and read their intensity in visual cues.
For example, red indicates heavy precipitation -- more than two inches an hour. They occur in a wide variety of shapes and sizes and manifest as a funnel of condensation surrounded by a cloud of dust and debris.
Typically, the wind speeds in a tornado reach more than mph (km/h) and the system is less than m across, but extreme events can be several miles across, with wind speeds of more than mph.

Get started now! - Hurricanes and the Coriolis Effect Hurricanes have been an active weather phenomenon throughout history. Thanks to our modern equipment, they are easy to track, yet still difficult to predict. Their destructive force causes millions of dollars in damage each time they hit land.
We use male and female names to name them. Describing Hurricanes, How They Occur and Their Devastating Power PAGES 1. WORDS View Full Essay. More essays like this: hurricanes devastating power, occrence of hurricanes.
Not sure what I'd do without @Kibin - Alfredo Alvarez, student @ Miami University.
Exactly what I needed. Each type of storm forms under specific conditions; hurricanes occur over moisture-rich oceans and coastlines, for example. They draw their energy from warm ocean waters.
Understanding the conditions that give rise to powerful storms is the key to preparing for their devastating effects.Download
