The National Oceanic and Atmospheric Administration (NOAA), a section of the U.S. Department of Commerce, defines hurricanes as being a “tropical cyclone, which forms over tropical or subtropical water,” that has reached a minimum wind speed of 74 mph (NOAA). These storms are typically intense and include strong winds, potential flooding, and additional storms (thunderstorms and tornadoes). This paper will provide a more in depth look at several aspects concerning these storms including: characteristics of hurricanes, where the storms form, what conditions are necessary for a hurricane to form, the life cycle, how the storms are measured, and what dangers a hurricane could potentially bring.
Hurricanes need two ingredients to form: warm ocean water and wind. There are four stages of a hurricane, depending on the wind speed: tropical disturbance, tropical depression, tropical storm, and hurricane. They first begin as tropical disturbances near the equator, where the temperature of the ocean water is at least 80 degrees Fahrenheit and winds are blowing approximately 23 miles per hour or less across the ocean surface. The wind causes water to evaporate and rise, forming cumulonimbus clouds. As evaporation and condensation continue, these clouds become larger and higher. Winds pick up to between 23 and 38 miles per hour, where the storm has become a tropical depression. Warm air rises and leaves the area with lower air pressure. Areas with higher air pressure move into the low pressure area. Then this warm air rises and more surrounding air moves in to take its place. The system of clouds and wind grow, fed by ocean water evaporating. As the system spins in a circle, an eye forms that is of low pressure. Higher pressure air from above flows into the eye of the storm. When winds reach 39 miles per hour, the storm is called a tropical storm. When winds reach at least 74 miles per hour, the storm is considered 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.
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.
Natural disasters occurring from the climate change could be on the rise. Global warming has been rumored to be causing more hurricanes, typhoons, cyclones, heavier monsoonal rains that cause major flooding, mud slides, and other disasters worldwide. A tropical cyclone, also referred to as hurricanes, typhoons, or cyclones, depending on where in the world the cyclone is occurring, are one of the world’s grandest shows of energy provided by nature. Hurricanes are large, swirling, low pressure storms that have sustained winds of over 74 miles an hour and are formed over warm ocean waters (NASA, n.d.). The purpose of this paper is to discuss hurricanes
Hurricanes are formed over tropical waters. These intense storms consist of winds over 74 miles per hour (Ahrens & Sampson, 2011). The storms addressed here are Hurricane Katrina and Hurricane Sandy. This paper will explore the contrasts and comparisons between these two horrific storms.
THESIS STATEMENT: One of nature’s most powerful and destructive storms are hurricanes. Although they can be deadly to humans and animals and have been known to cause extensive destruction, they also play a very important and beneficial role on Earth.
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
Hurricane Katrina included many details common to hurricanes. The wind speeds of hurricanes usually have a span from 150 mph to 200 mph. Most hurricanes have temperatures of 80 Degrees Fahrenheit at the very least. When the wind speeds sustain 39 mph it’s considered a tropical depression, or a tropical storm, and is then given a name. When the wind speeds reach 75 mph, it’s then considered a hurricane and is measured on the Safire-Simpson Scale. On the scale they rate the storm from a one through five, depending on their wind speeds and how fast the hurricane is traveling. Hurricanes form
The scientific definition of a hurricane is “an intense storm of tropical origin, with sustained winds exceeding 64 knots, which forms over the warm northern Atlantic and eastern North Pacific oceans” (Ahrens 316). Each year, from approximately June 1st to November 30th, the world is forced to suffer through hurricane season. Through the duration of this time period hundreds of storm systems emerge from the tropical regions which surround the equator. From these countless storms over 50 will intensify to hurricane levels.
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
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
Essentially, a hurricane is just a big storm. Hurricanes are formed when the moisture in the air evaporates and rises up until the heated moisture is twisted into the atmosphere. The cold and hot air will start “chasing” each other anti clockwise, and can reach speeds of 75 miles per hour.
What risk does hurricane pose to social vulnerable population and how do they prepare? People get more vulnerable when the disaster strike comparing to the power associated with a hurricane. ¬Hurricane Katrina will not be faded easily from people’s memories for a long time, because of the magnitude of the losses.
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
Have you ever wonder how a hurricane forms? Here are how they form, According to https://eo.ucar.edu/kids/dangerwx/hurricane3.htm “Hurricanes happen when the oceans have been warmed during summer months.”The ocean has to be at least 80 degrees fahrenheit for a hurricane to happen. “In the North Atlantic, hurricane season is from June 1 to November 30, but most hurricanes happen during the fall.” If you live near water you have a high risk of having hurricanes in the fall.” Now that you seen how they form here are some ways they track hurricanes.
