Chapter four of our textbook, while making the aspect of physical geography a priority concerning weather and climate, take special care in introducing the topic of hurricanes as well as changes in air pressure and ocean currents. Hurricanes can be described as low-pressure areas which begin over warm waters. As they develop, hot, humid air at the surface rises which aids in the suction of air. This causes cumulonimbus clouds to appear. The energy these clouds release warms the center which contributes to the distinctively calm core commonly referred to as the eye.
Deadly and destructive. These are two words that describe the horrible natural disaster we now call a hurricane. An average hurricane can cause thousands, millions, or billions of dollars in repairs! Scientists are always trying to warn people when a hurricane could be coming, but even scientists make mistakes so, just like other natural disasters, you should always be prepared if a hurricane does come your way. A hurricane can be very deadly if people are not prepared or on high land. A hurricane can be very deadly and destructive even if you are ready for the oncoming hurricane. Deadly and destructive.
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 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.
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
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.
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.
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
Hurricanes are large, twirling storms that bring strong winds that can blow up to 74 mph or higher. There are two main ingredients that hurricanes need to form, warm water, and consistent winds. If a hurricane does form, it will include the eye, which is the clam center of the storm, around that there is the eye wall which is normally the strongest part of the storm, on the edges of the hurricane are the rainbands, which are swirling “arms” of clouds, rain, and thunderstorms, they can stretch out from the eye for hundreds of miles. After a hurricane forms it is tracked by meteorologists, and other scientists researching the storms, these people categorize it using the Saffir-Simpson Hurricane Scale, this scale is measured in five categories, category one has winds 74-95 mph, category two has winds 96-110 mph, category three has winds 111-129 mph, category four 130-156 mph, and finally category five has 157 mph winds and higher.
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
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.
In other words they draw heat from warm, moist ocean air and release it through condensation of water vapor in thunderstorms. Hurricanes spin around a low-pressure center known as the “eye.” Within the eye, all is calm and peaceful. But in the cloud wall surrounding the eye, things are very different although hurricane winds do not blow as fast as tornado winds a hurricane is way more destructive. This is because tornado winds cover only a small area, usually less than a mile across-‘hurricane’s winds may cover an area 60 miles wide out from the center of the eye. This storm brings destruction ashore in many different ways. When a hurricane makes landfall it often produces a storm surge that can reach 20 feet high and extend nearly 100 miles long. Ninety percent of all hurricane deaths result from storm surges. A hurricane’s high winds are very destructive and can actually cause another storm called a tornado. The Torrential rains cause further damage by floods and landslides, which can happen many miles inland. A good thing about hurricanes is you can see them coming and it gives people time to get out of its way. The National Hurricane Center issues hurricane watches for storms that may endanger communities, and hurricane warnings for storms that will make landfall within 24 hours. In 2005 Hurricane Katrina killed over 1800 people in the United States and caused around $80 billion dollars’ worth of property damage. New Orleans was hit
It’s important to understand Geoscience while studying hurricanes. By understanding Geoscience, we understand how the earth heats and cools and this plays a major role in the creation of hurricanes. Hurricanes form when an area of warm water heats the air above it, causing that air to rise. This creates an area of low pressure. The higher pressure around this area pushes new air in, which heats up and also rises. This flow of air causes the clouds to swirl. If the storm is in the northern hemisphere,
