Saffur-Simpson Hurricane Research Paper

As storm relative velocity helps analyze the motion of the winds within the storm, information like the rotation of the storm and the speed of the winds can help investigate the chances of the storm developing into a tornado. If the storm appears to be a threat, nearby communities can be notified to take precautions and leave if necessary. Although base velocity can be used for the same reason, the speed of the storm can affect the results of the speed and rotation of winds. Therefore, storm relative velocity is more accurate and reliable than base velocity in determining the threat of a

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 are really just big storms. They can be up to 600 miles across, some wind speeds can go up to 200 miles per hour. Hurricanes put together heat and energy from all around warm water oceans. There are 5 categories to each hurricane, level 1 is winds 74 to 95 miles per hour, level 2 is winds of 96 to 110 miles per hour, level 3 is 111 to 130 miles per hours, level 4 is winds of 131 to 155 miles per hour, and level 5 winds are more than 156 miles per hour. When hurricanes come to land with the heavy rain they’ve carried, along with very powerful winds, and huge waves they can leave a lot of damage.

There are several stages in a hurricane. The first stage of a hurricane is a category one. To be a category one hurricane the hurricane must have a maximum sustained speed of at least 74-90 mph.(119-153 km) To be a category two hurricane the wind speeds will he about 96-110 mph(154-177 km). A category three hurricane and higher is considered a major hurricane. A category three hurricane has winds of 111-129(178-208 km) mph. A category four hurricane has winds up to 130-156 mph (209-156 km).A category five hurricane has winds up to 157 mph () or higher because they have not classified a category six to limit the category 5 hurricane mph. The word hurricane also means typhoon. Typhoons are called typhoons because they are mostly in coastal

Hurricanes are, highly dangerous and large swirling storms that begin over water and they sometimes end up on land. On October, 4th 2016 Hurricane Matthew hit the coasts of Haiti with 130 to 150 mph wind speeds which means it was a Category 4 hurricane. Hurricanes such as Matthew are tracked by forecasters whose job is to give people watching or listening an idea of strong the winds are. The forecasters use a scale called the Saffir-Simpson Hurricane scale it is used to track the winds and categorize the hurricane. The scale has 5 Categories beginning at 74 miles per hour and ending 157 mph and it can go even higher. Lastly, a hurricane has three parts, first the rainbands, the rain bands have rain, thunderstorms and sometimes tornadoes, next

According to the National Ocean Service, an organization that strives to protect coastal areas, a hurricane is defined as “a type of storm called a tropical cyclone, which forms over tropical waters” (1). That is to say, when a storm sustains winds with a count greater than 74 miles per hour, it is officially classified as being a hurricane. Generally originating over the Atlantic Ocean, hurricanes are formed when air from surrounding regions with high pressures rush to low pressure areas, causing the air above such warm, tropical waters to rise. As the warm, moist air rises and slowly cools off, water in the air begins to form clouds. Overtime, the number of clouds and strength of the winds significantly increases as a result of the heat and water evaporating from the ocean’s surface, creating a strong rotating storm that is soon recognized as being a tropical

When a hurricane occurs it mainly starts because of a tropical storm. For a hurricane to occur you there is going to be warm water from somewhere near the equator or the Atlantic and Pacific ocean. Then when the water evaporates there should be strong winds. The wind starts to go in a circle clockwise. It should depend where the hurricane will start to see where it is going. If it is in the Atlantic ocean it will start going towards Africa. (Hurricanes." The Gale Encyclopedia of Environmental Health, edited by Jacqueline L. Longe, vol. 1, Gale, 2013, pp. 431-433.

A hurricane is an extremely dangerous/violent Thunderstorm which normally happens in tropics and can travel up 74 miles per hour in wind speed. Hurricanes are one of the most deadliest natural disasters in the world.

Hurricanes first start out as a tropical depression and then gain strength into a tropical storm. When a tropical storm reaches 74+ miles per hour they turn into a category 1 hurricane, they increase in intensity, they go all the way through a category 5 hurricane. Category 1 hurricanes have a wind speed of up to 95 mph. A category 2 hurricane has wind speeds of up to 110 mph. Category 3 hurricanes reach up to 129 mph. A category 4 hurricane reaches up to 156 mph. The deadliest hurricane, a category 5 exceeds wind speeds anything above 157 mph. A hurricanes only form over warm waters. Damp air fuels the forming storm. The warm air gets water from the ocean and becomes moist. This moist air rises towards the surface, when air from surrounding

Hurricanes are the most powerful storm on earth. The speed of a hurricane is very quick. The text states, “To be classified as a hurricane the wind from rotating storm must reach at least 74 miles per hour, through the strongest hurricanes will have winds in excess of 150 miles per hour.’’ In different hemispheres the winds of a hurricane rotate differently. The text states, “In the northern hemisphere the winds rotate counterclockwise. In the southern hemisphere, they rotate clockwise.’’ Some hurricanes have different sizes. The text also states, “Typical hurricanes are about 300 miles wide, although they vary considerably in size.’’ Usually, the strongest hurricanes are in warm seas because with atmospheric conditions that allows the storm to rotate

According to Tropical cyclones with maximum sustained surface winds of less than 39 miles per hour (mph) are called tropical depressions. Those with maximum sustained winds of 39 mph or higher are called tropical storms (What). After winds reach 74 mph, that is when it’s considered a hurricane. The Saffir-Simpson Hurricane Wind Scale is a 1

The eye of the hurricane is the middle part which is the most calm. The eyewall is the outside, which is the most dangerous part of the hurricane. Wind is when the air moves. The Saffir simpson scale is a scale used to find how bad a hurricane is. A hurricane watch is a warning to everyone in the area that wind is a high speed.

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).

A specific name is assigned to a tropical storm and/or hurricane for a multitude of reasons. The first reason a tropical storm and/or hurricane is assigned a specific name is because more than one tropical storm and/or hurricane may exist at a given time. By simply giving a tropical storm and/or hurricane a name, it becomes easier for meteorologists and the general public to effectively keep track of and talk about storms. Conversely, not every minor storm is given a name. A storm is only assigned a name if it reaches tropical storm strength; this name stays with the storm if it goes on to form into a hurricane. Moreover, each year, tropical storms are appointed in alphabetical order as they occur. It is important for the readers to recognize

It is relatively easy to see a hurricane's strength using the Saffir-Simpson scale; just measure the wind speed, or do a little bit of math to find the wind speed. To calculate the hurricane's strength using a new index, the Cyclone Potential Index made at the National Center of Atmospheric Research in Colorado, you need to incorporate a few more variables, such as sustained wind speed, atmospheric winds, speed of the hurricane’s movements, size, or more. This scale was made to more accurately represent a hurricane’s power. On the scale, Hurricane Katrina was a 4.9, Harvey was 5.2, and Irma is a 5.3.
