Imagine climbing on top of your house or a raft with your family, desperately waiting for the rescue crew to come. These events are caused by hurricanes, but did you ever wonder how these vortexes of destruction came to be? Hurricanes are very large storms that has winds that can at least blow at 119 kilometers per hour (74 miles per hour) These natural disasters usually cause floods, power outages, and lots of wind. Hurricanes always have a name to classify which is which, and they also are categorized into categories.
The science behind it
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.

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 winds of more than 252 km per hour (157 mph). But before a hurricane gets categorized it usually starts out as a tropical disturbance. This is when rain clouds accumulate over an area with warm ocean waters. After the tropical disturbance is a tropical depression, this is when the rain clouds become thunderclouds and winds go up to 62 km per hour (38 mph). Tropical depressions then become a tropical storm when its winds reach 63 km per hour (39 mph) Finally, a tropical storm becomes a hurricane when it when its winds reach 119 km per hour (74 mph). A hurricane has many parts that contribute to its damage. One of them is the eye, the eye is the center of the storm, this area usually is the most serene of the storm. The next part of the hurricane is the eye wall, this is a ring of thunderstorms
(Spring, Texas) A Category 4 storm, Hurricane Harvey did extensive damage to the state of Texas, causing $180 billion dollars in damage. Approximately 13 million individuals in five states were impacted. Sadly, 82 of these individuals lost their life. What made this storm so challenging was it made landfall three separate times over a six day period, and 1/3 of Houston was underwater at one point. As a result, numerous families are now contending with high moisture levels and other issues in the home, and Air National remains on call to help these individuals.
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
The Galveston Hurricane of 1900 was a natural disaster that left the people of Galveston with an unimaginable and terrifying experience,various personal stories, and a massive cleanup job that led to building the sea wall and raising the elevation of the city. The Galveston Hurricane of 1900 was the biggest natural disaster in American history. When it came there was little warning and once the citizens were warned it was too late to leave. The waves and rain from the hurricane flooded the whole city over fifteen feet high with water. During the storm people experienced many events that would change their lives. Everyone who survived this hurricane had a story, a story that could be tragic, happy, or full of stress. Once the storm was over there was an immense amount of debris that needed to be cleaned up. The people of Galveston had to look for bodies and people who were buried alive. Galveston had to rebuild everything and start all over. The people living there came up with an idea to build a seawall that would protect Galveston from large waves created by another hurricane. They then also raised the city by as much as 17 feet in some areas.
The eyewall is a ring of tall thunderstorms that surrounds the eye. The fiercest winds are here -- up to 112 mph with gusts up to 189 mph. The rainbands are these curved bands are packed with thunderstorm clouds. They can reach hundreds of miles from the eye and produce rain, lighting, and, sometimes, tornadoes.” The Saffir-Simpson Scale shows you the intensity of the hurricane. According to Inside Hurricanes by Mary Kay Carson, “Category 1 is the weakest of the 5 categories and has wind speeds ranging from 74-95 miles per hour. Category 2 wind speeds range from 96-110 miles per hour. Category 3 has wind speeds ranging 111-130 miles per hour. The wind speeds in Category 4 range from 131-155 miles per hour. Category 5 is the strongest which have winds speeds that reach up to 156 and above miles per hour.” When it comes to hurricanes everyone wants you to be as safe as possible, so there is two things that you should be on alert for; they are hurricane watches and hurricane
Mother Nature cannot be controlled and as humans we are forced to deal with various natural disasters. We have earth quakes, hurricanes, volcanoes, tornadoes and many other types of events that are weather driven. Many natural disasters affect our everyday lives and individuals may be forced to safe areas to protect themselves from potential danger. Natural disasters can also place a financial burden on people in affected communities. Hurricanes are strong storms that have been hitting the United States for as long as history can remember. Many hurricanes have hit the southeastern part of the United States the past 100 years. Some of these hurricanes have left little effect of society while others have scarred into the history
Forecasting hurricanes has two components to it: where the hurricane is going (track) and how strong it is going to be (intensity). Hurricane forecasting has improved over time, “In 1992, hurricane forecasts were issued to only three days, but now they are issued to five—and soon they will be given for up to a week.” (Main). Predicting hurricanes is extremely difficult, but the development of faster computers and better satellite data has decreased the error percentage of forecasting hurricanes.
Disaster Relief: Hurricanes Annotated Bibliography 2017 was a record breaking year for hurricanes. Victims of hurricane Harvey, hurricane Maria and hurricane Irma are still struggling. Many people are unaware of the impacts of these hurricanes and how much help is needed. Shelters are over capacitated, victims are still without a home and help is still needed. Hurricanes this year have caused a huge impact on our land and our people.
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)
A hurricane is easily the most powerful storm that mother nature can throw at us. Every year, people who live on the coasts fight hurricanes with no dismay. A hurricane is simply too strong. Their winds reach speeds of 75 mph. Winds around the eye wall can reach 130 to 150 mph.
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.
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...
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 are powerful atmospheric vortices that are intermediate in size. Hurricanes are unique and powerful weather systems. The word “hurricane” comes from a Caribbean word meaning “big wind”. Views of hurricanes can be seen from a satellite positioned thousands of miles above the earth.
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...
Though there are many factors in the formation of a hurricane, it all starts with having warm ocean water, mainly around summer and early autumn. Hurricanes form in low-pressure areas in which winds in the low levels of the atmosphere converge and uplift. The water vapor from the heated ocean water is the energy source for the hurricane. The water must be warm enough to put heat and moisture into the atmosphere. The atmospheric moisture combines with the energy or ‘fuel’ and propels the hurricane. The wind must maintain itself in order to become a hurricane. Hurricanes continue to grow stronger while they are traveling over warm ocean water. Once a hurricane reaches a mass of cold ocean water or land, they lose their source of fuel and gradually decrease in power and size. Hurricanes cause great amounts of damage to coastal land when the hurricane is fresh off warm water.
