Intro Imagine you’re at home, watching TV. It’s pouring rain outside, and you are as comfy as ever. All of the sudden, the wind picks up and the rain falls harder. You hope it’s a cloud burst, but on the television you have heard hurricane warnings. Your face goes white as you realize a horrific storm is on it’s way. Hurricanes are enormous storms with pouring rains and whirling winds that happen between August and October. (Sometimes even in early November.) Though it’s very important, many people don’t know the danger of hurricanes. Body 1: How hurricanes are formed Hurricanes always start out as tropical disturbance. Rain clouds build over warm tropical waters. Once this has happened, the storm turns into a tropical depression. The rotating winds start out at about 38 miles per hour (61 km per hour). The tropical depression morphs into a tropical storm when winds hit 39 mph ( 62 kn per hour). If the winds reach 74 mph (120 km per hour) the storm is officially a hurricane. But hurricanes are not only dangerous on land, they also hurt the sea animals who are slow or refuse to leave their homes. …show more content…
Hurricanes are terrifying storms with winds swirling at at least 74 miles per hour or higher (Hurricane Irma once got to 180 mph) Once the hurricane reaches the shore, it creates a huge wave called a storm surge. Because of their big rains, hurricanes can cause massive flooding problems. Sometimes, peoples homes flood and people have trouble evacuating, or even drowning. Because of Hurricane Harvey, over 30,000 people will need short-term shelter and food. What is worse, Harvey also gave Housten, Texas four feet of rain. In one day, the Huricane had dumped 14-15 trillion gallons of
Florida’s state flag is a white background and a big red “X” and the flag has the state motto “In God we trust” and also says “Great seal of the state of Florida” the picture is a American woman purposely dropping flowers,a steamboat, a palmetto tree,and a beautiful sun.
The birth of a hurricane requires at least three conditions. First, the ocean waters must be warm enough at the surface to put enough heat and moisture into the overlying atmosphere to provide the potential fuel for the thermodynamic engine that a hurricane becomes. Second, atmospheric moisture from seawater evaporation must combine with that heat and energy to form the powerful engine needed to propel a hurricane. Third, a wind pattern must be near the ocean surface to spirals air inward. At least 3 conditions must be present for a hurricane to emerge. Water, heat, and wind are the three main factors that have to be in perfect conditions to start a hurricane. (The Weather Channel, 2008)
Hurricane Harvey was one of the most devastating hurricanes to strike the United States in several years. Harvey resulted in over eighty fatalities and over 150 billion dollars in damages. This proves to be one of the most destructive hurricanes to be recorded. The overwhelming damage was caused by many different aspects; however, three of the greatest aspects are: varying weather patterns throughout the storm, the city structure of Houston, Texas, and the lack of evacuation. Each of these factors affected the city in a different way, but all resulted in a common outcome, devastation.
Hurricanes form over the ocean. Easterly waves, what hurricanes develop from, are long, narrow regions of low pressure which occur in ocean winds called trade winds. At first, these easterly waves can grow into something called, a tropical depression. A tropical depression occurs when winds are up to 31 mph. Then tropical depressions can be upgraded into a tropical storm if the winds reach speeds of 74 mph or less. Then finally a the storm can be bumped up into a hurricane if the winds reach 75 mph.
Hurricanes are born over the warm waters of tropical oceans and are formed by a low-pressure system caused by the heating of water. The heat causes the air to rise and form lower pressures in a feedback loop, making the hurricane stronger. Heavy rain results from a condensation of water and strong winds develop from warm air rushing to the eye of the hurricane. Essentially, greater storms and winds occur when the hurricane feeds of the rising temperature of the water. In addition, researchers studied disturbances and intense thunderstorms in the atmosphere over Western Africa and believe they are partly to blame for extreme hurricanes affecting the United States and Canada. While these are all the main ingredients of a perfectly natural process, they were not the primary causes of the damage done by Hurricane
Hurricanes are powerful and destructive storms that involve great rain and wind. The United States of America has dealt with many hurricanes that have cost a great amount of damage. However, there is one hurricane that happened in 2005 that stands out among the others, Hurricane Katrina. Hurricane Katrina was one of the worst hurricanes to hit the United States, a category 5 on the Saffir/Simpson Hurricane Scale. An estimated 1836 people died because of the hurricane and the floodings that happened after (Zimmermann 1). Katrina initially beg...
In the hurricane the mixture of the water and winds can be extremely damaging. The winds are extremely dangerous and usually don’t go faster than about 75 miles per hour but have been documented to go as fast as 85 miles per hour. Due to the fact that hurricanes need water to survive they cannot go too far on land, but that does not stop them from causing billions of dollars in damages. Hurricanes are so dangerous that they were listed number 1 on the Department of Earth and Atmospheric Sciences, Hazard and Disasters list.
Hurricanes begin as tropical disturbances in warm ocean waters with temperatures of at least 80 degrees Fahrenheit. These low pressure systems are served by energy from the warm seas. If a storm reaches wind speeds of 38 miles an hour, it is known as a tropical depression. A tropical depression becomes a tropical storm, and is given a name, when its sustained wind speeds top 39 miles an hour. When a storm’s sustained wind speeds reach 74 miles an hour, it becomes a hurricane and earns a category rating of 1 to 5 on the Saffir-Simpson scale.
If the tropical disturbance continues to grow, it is then called a tropical depression, an area of rotating thunderstorms has winds of 38 miles per hour or less. A tropical depression becomes a tropical storm if its winds reach 39 miles per hour. Finally, a tropical storm becomes a hurricane when its winds become greater than 74 miles per hour. So, you can say that in short, a hurricane is a storm with fierce winds. Hurricanes are categorized into five categories using the Saffir-Simpson Hurricane Scale.
D. Thesis: In order to better understand tornadoes, it is important to explore what causes tornadoes to develop, how researchers classify types of tornadoes, and odd occurrences that may be associated with tornadoes.
Hurricanes originate as tropical disturbances over warm oceans with trade winds. The tropical turbances intensify into tropical depressions, and eventually into a tropical storm. They only originate in the tropical trade winds because the ocean temperatures are quite warm there. Powered from the heat that the sea gives off, they are steered by the east trade winds and the temperate west ones, as well as by their own ferocious energy. Around their core, winds grow with a tremendous amount of velocity creating violent seas. As they move toward the shore, they move the ocean inward, while spawning tornadoes and producing torrential rains and floods.
A Hurricane is a tropical storm with winds more than 74 miles per hour (mph). Hurricane wind damage is influenced by the duration and change of wind direction, amount of rainfall and how well land structures are build. Hurricanes are measure in five different categories and each category can produce different degree of damages. Category One Hurricane has sustained winds 74-95 mph. Category Two Hurricane has sustained winds of 96-110 mph with very strong winds that can produce widespread damage and extensive damage to power lines. Category Three Hurricane has sustained winds of 111-130 mph that will cause extensive damage with near total power loss that could last several days to weeks. Category Four Hurricane has sustained winds of 131-155 with extremely dangerous winds causing devastating damage. Finally, a category five hurricane has sustained winds greater than 155 mph. This is a catastrophic damage storm. Category five can have severe injury or death due to wind blown debris. A Category five hurricane can produce extensive power outages that will last for weeks to perhaps months. Therefor...
A hurricane can be defined as than 64 knots (74 miles per hour; 119 kilometers per hour), originating in the equatorial regions of the Atlantic Ocean or Caribbean Sea or eastern regions of the Pacific Ocean, traveling north, northwest, or northeast from its point of origin, and usually involving heavy rains. Hurricanes are a natural disaster with far reaching consequences. It takes away the lives of millions of people and causes damage to almost all of human creation. It can cause extensive damage to coastlines and several hundred miles inland due to heavy rainfall. It takes away the lives of millions of people and causes damage to almost all of human creation.
A hurricane is a type of natural disaster that can be harmful and destructive to anything in its way. Every year five to six hurricanes are formed, damaging and destroying people’s homes, landmarks, and anything in its path (“Hurricane”). Before a hurricane is developed it is known as a tropical storm. To be a tropical storm wind speed must be at least thirty eight miles per hour (“Hurricane”). Once wind speeds reaches seventy four miles an hour it can then be classified as hurricane (“Hurricane”). Large scale storms, like hurricanes have a variety of ways to measure the sev...
