A hurricane is a tropical cyclone, with winds that reaches over 74 miles per hour. In the Southern Hemisphere a hurricane circulates clockwise, and in the Northern Hemisphere it circulates counterclockwise. Hurricanes usually occur during the summer and fall seasons because that is when the water temperature is at its warmest. There are various stages that a hurricane goes through to become one and there are also various ways to track down a hurricane too.
The first stage of a hurricane is called a tropical disturbance. The wind speed is less than twenty-five miles per hour, with a slight open circulation going on. The tropical disturbance consists of clouds, showers, and thunderstorms, which remain intact for twenty-four hours or more. Tropical waves are the most common tropical disturbance, and about one hundred of these waves form each season. This wave usually develops about every four to five days.
The second stage of a hurricane is called a tropical depression. During the tropical depression the open circulation closes, and the winds speed have usually picked up to twenty- th...
Firstly hurricanes, otherwise known as tropical-cyclones, are formed over warm ocean waters of at least 26.5ºC through depths of at least 45m. There must also be a high Coriolis Effect present such as there is just north and south of the equator. (Moran, 2011) Hurricanes begin as smaller storms called tropical disturbances, if the storm experiences a sufficient loss in surface air pressure coinciding with a strengthening sustained wind the storm is then upgraded to a tropical depression. As the storm continues to intensify and the wind speeds reach 63km/h it then becomes a tropical storm and is finally given a name. When the storm continues to grow in strength and reaches wind speeds of 119km/h it then becomes a hurricane. (Moran,2011)
The development of the storm was initiated by an apparent tropical wave that had given way of the African Coast around August 5th. The cloud pattern of the storm slightly resembled that of an inverted “V” began traveling westward, then northward, across the Atlantic Ocean and was recognized as a tropical disturbance 4 days later, August 9th. The following 5 days or so the storm continued to travel showing no sign of circulation. On August 14th the United States Air Force sent a reconnaissance aircraft into the storm for surveillance, with a growing concern. What was about to be Tropical storm Camille was still south of Cuba with expectation to become much more potent. At the point of infiltration by the aircraft the planes barometer revealed a 999 millibar pressure center with 55 mile an hour surface winds. At this point the disturbance was inaugurated to be a “tropical storm.” As the intensification process ensued, and the squall shifted northwestward at a slow speed of 9 miles per hour, but gained a great amount of force in...
Hurricane preparation is the most important thing in staying safe during a hurricane. Through technology we are able to track these hurricanes and have time to get ready for them. Recovery takes a lot of time and work, but safety and injury prevention should be your number one concern.
system, or one making landfall just a few nautical miles further to the north, would have
Leading up to the hurricane, many scientists expected the storm to dissipate over the ocean and cause little to no harm (Rappaport). The scientists were relying on faulty equipment that said that due to slow air speed and l...
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
More than a dozen deaths, billions of dollars in damages and thousands of families that lost their entire lives in just over seven days. By the last week of the month of August, 39 counties in Texas were stripped of their valuables due to the massive flooding. The great cause of the damage was Hurricane Harvey, a category four storm making it one of the biggest hurricanes to ever make landfall in Texas. People from all over the country reached out and became one to aid victims of this natural disaster. Only month after the storm Texas still battles to surpass the emotional and physical damage that this storm created for our people.
In James S. Hirsch’s book about Rubin "Hurricane" Cater, Hurricane, the author describes how Carter was wrongfully imprisoned and how he managed to become free. Hirsch tells about the nearly impossible battle for Carter and his friend John Artis for freedom and justice. Both, Carter and Artis, were convicted of a triple homicide, and both were innocent.
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.
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)
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 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.
Hurricanes are one of the deadliest and most expensive natural disasters around. They are more common in areas of humid yet moist weather so they are very foreign to certain places. But to the places were hurricanes are the norm, the people take them extremely seriously because they kill people and ruin countless amounts of property. Hurricanes can attack and harm people in so many ways they can kill people, leave them homeless, it leaves children orphaned and disable them. On the west coast of the United States and other places hurricanes aren’t taken as seriously as other more common disasters, such as, earthquakes and volcanoes yet the hurricane can be a lot more damaging that both of those. Hurricanes are cyclones that develop over warm oceans and breed winds that blow yup to 74 miles per hour.
For a hurricane to form, the ocean temperature must be warmer than twenty-six degrees Celsius, or eighty degrees Fahrenheit. Also, the air near the oceans surface must be filled with moisture. The seawater that is warmed by the heat from the sun evaporates to form vast storm clouds. As the warm air rises, the cooler air replaces it thus creating a wind. The rotation of the earth bends the wind inward causing it to rotate and spiral upward with a great amount of force. Around the Equator, the spin is the fastest. There, it can be faster than six hundred miles per hour.
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...
