The Saffir-Simpson Hurricane

Hurricanes are a tropical cyclone, which means a rotation of closed low-level circulation of clouds and thunderstorms that originate from tropical and subtropical waters. Hurricanes are categorized by five categories, which determine the wind speed, the surge, and the pressure of a storm. These five categories help people be aware of how dangerous hurricanes can be: 1-minimal, 2-moderate, 3-extensice, 4-extrme, 5-catastrophic. Categories 1 and 2 have winds between 74-110 miles per hour, with a flow of 4-8 feet of water, and a sea level pressure of 980-979 millibars.

Hurricanes form over the equator in warm ocean waters. First in a hurricane the winds start to pick up wind on the average reach about 39-73 mile per hour,th but in the great Galveston the winds reached 145 miles per hour the power of the wind can take down trees, houses and building. it rains very hard it is not uncommon during a hurricane to get 5-10 inches of rain. It’s also very common to get floods from the storm surge that averages 25-28 feet above sea level. Even though it is very rare tornadoes

Over the past few centuries, the natural disaster of hurricanes has had a huge impact on the land around us. It could cost millions, or even billions of dollars in repairing the damages done by hurricanes. These natural disasters can not only result in property damage but also many lives lost and injured victims. Hurricanes usually leave many without homes, forcing victims to find shelters or relocate to a different city or state for safety. A hurricane is a violent, tropical, cyclonic storm with sustained winds of at least 64 knots (74 miles per hour: 119 kilometers per hour) that are extremely large, powerful, and destructive. Hurricanes usually start to occur over large areas of warm water, such as the Atlantic Ocean. They generally form during the hotter months due to the fact that it gets energy from the heat off the water.

As many know, hurricanes are considered to be among the most powerful forces in nature. A hurricane is a powerful storm system that produces intense winds and heavy rainfall. Hurricanes form over warm ocean water during warm months such as June, July, and August which is known as the

The Saffir-Simpson Hurricane Wind Scale is a 1-5 category based on a hurricane’s sustained wind speed. This scale estimates the potential property damage. Category 3,4 and 5 Hurricanes are considered major hurricanes because of their potential to be deadly and damaging (Saffir-Simpson Hurricane Wind Scale).

The hurricanes are usually considered intense storms of tropical regions characterized by strong winds exceeding seventy-four mile per hour, low-pressure center and thunderstorms. The center of hurricane the winds are usually light and the clouds are broken reason for that is air

Scientific proof is that stronger hurricanes can reach up to forty to fifty feet high in the sky and can range in mph. The hurricane needs the Coriolis force to form. It is stronger in the Northern Hemisphere and weaker near the Equator. The Southern Hemisphere experiences half the hurricane activity that the Northern does. When the hurricane forms, it can be large enough to carry winds of exasperating speeds and reach a diameter measurement of 600-800 kilometers (conserve-energy-future.com). The eye of the hurricane can be as large as thirty-two kilometers. What is strange is in the eye, the wind is usually calm. The temperature and weather place factors in the

The Saffur-Simpson Hurricane Scale is a scale made up of 5 categories of Hurricanes. The categories are ordered by the speed of the Hurricane.

A hurricane needs a couple of components to survive. One of them is warm water and the other is winds going the same direction. If a hurricane didn’t have either of those, it wouldn’t last very long or be destructive. Scientists categorize hurricanes by its wind speed using the Saffir-Simpson Hurricane Scale. There are 5 categories for a hurricane and each can do dangerous damage. A category 1 hurricane would have winds of 119 to 153 km per hour (or 74 to 95 mph). A category 2 hurricane would have winds going from 154 to 177 km per hour (96 to 110 mph). A category 3 hurricane has winds of 178 to 208 km per hour (111 to 129 mph). A category 4 hurricane has winds of 209-251 km per hour (130 to 156 mph). And finally, a category 5 hurricane has

Hurricanes are considered a major force of nature. The high speed winds and heavy rain make a great combo for the demolition they cause. The hurricane’s wind speeds are are major part of the hurricane actually becoming a hurricane. The way it forms is when warm and moist air rises from the surface. When the air rises it causes a drop in pressure below the warm and moist air.

On the morning of August 29th, 2005, and unimaginable event occured. The destruction this event would bring to the people of New Orleans, Louisiana was nothing that could be predicted. It was known as Hurricane Katrina. The Gulf Coast of The United States is where Katrina struck. When the storm first awoke it had been rated as a Category 3 Hurricane on the Saffir-Simpson Hurricane Scale. The Saffir-Simpson Hurricane Wind Scale or also referred to as SSHWS is what is used in the classification of hurricanes. This system differentiations tropical storm or tropical depressions into five different categories based on the level of their intensity of the winds. With reaching winds up to 140 miles per hour and width holding up at 400 miles wide from

Hurricanes are big storms in the ocean that are large, swirling storms with strong winds. The water that is pushed onto land is a storm surge and it is said that they are the most dangerous part of the hurricanes that go on the land. A Category one, winds can get up to seventy-four miles per hour. Category two, winds can get up to ninety-six miles to one-hundred-ten miles per hour, a Category threes, winds can get up to one-hundred-eleven to one-hundred-twenty-nine miles per hour. Category four hurricanes can get up to one-hundred-thirty miles per hour, Category five hurricanes are the worst ones of all and the wind speeds can get up to one-hundred-fifty-seven miles per hour and then it can destroy anything in it’s path. The Eye of the

Hurricanes have some key factors to them. One is that hurricanes are scaled on the Saffir-Simpson scale. The Saffir-Simpson scale goes from 1-5, 5 is being the strongest and 1 being the weakest. All hurricanes are formed over the ocean, if the hurricane has a lot of time forming over the ocean it will be a strong hurricane. Some hurricanes will start off as a tropical storm and some will end as a tropical storm.

Hurricanes are gigantic, swirling, tropical storms that are created with a wind speed over 160 miles (257 kilometers) per hour. It gives off more than 2.4 trillion gallons (9 trillion liters) of rain each day. Hurricane forms in the Southern Atlantic Ocean, Caribbean Sea, Golf of Mexico, and in the Eastern Pacific Ocean. According to www.weatherwizkids.com , a hurricane usually lasts for a week. Hurricane mostly occurs at mid-August to late October and occurs about five to six times a year. A hurricane begins at a tropical disturbance in warm ocean water with a temperature of at least 80 degrees Fahrenheit (26.5 degrees Celsius). The center of a hurricane is call the “Eye of the Hurricane” and is about 20-30 miles wide (32-48 kilometer wide). The eye is the calmest part of a hurricane and surrounding the eye is something call the “Eye Wall”. When a hurricane makes a landfall, it often produces a strong storm surge that can reach 20 feet (6 meters) long and spread 100 miles (161 kilometers).Hurricanes cause catastrophic damage to coastlines and several hundred miles in land.

A category three hurricane is defined as having wind speeds from 111 to 130 mph with a storm surge of nine to twelve feet, and doing some structural damage to small residences and buildings. A category four hurricane sustains winds of 131 to 155 mph with a storm surge of about thirteen to eighteen feet. In a category four hurricane, shrubs, trees, and all signs are blown down and there are some complete roof structure failures on small residences. Land lower than ten feet above sea level can become flooded, resulting in evacuations of residential areas that are as far inland as six miles. A category five hurricane sustains winds of greater than 155 mph with a storm surge greater than eighteen feet. In a category five hurricane, there is complete roof failure on many buildings and residences with some buildings being completely blown over or blown away. At this point, all signs, trees and shrubs are blown down, there is complete destruction of mobile homes, and excessive flooding can occur (White p.30).
