**//__Features Of A Hurricane__//**


//__What Are The Physical Feature Of A Hurricane__// Physical fetures of a hurricane really begins when the hurricane forms. A hurricane forms in low pressures zone which then forms into a tropical wave of low pressure. Hurricanes require tropical water which is above 27 degrees celsius and a depth of 50 meters. Hurricanes spin in an anti-clockwise roation. Hurricanes are split up in to categorys 1-5 depending on how strong the wind is. Category 1: Wind speeds which range from 75-95 mph very light damage to buildings and very little flooding. Video of Category 1 hurricane http://www.youtube.com/watch?v=JpA23YA7GKk Category 2: Wind speeds which range from 96-110 mph light damage to buildings and little flooding. Video of Category 2 hurricane [] Category 3: Wind speeds which range form 111-130 mph medium damage to buildings and medium flooding homes should be evacuated. Video of Category 3 hurricane [] Category 4: Wind speeds which range from 131-155 mph heavy damage to building and heavy flooding homes will be evacuated. Video of Category 4 hurricane [] Category 5: Wind speeds which range form anything over 156 mph extreame damage to building and extream flooding homes will be evacuated. Video of Category 5 hurricane http://www.youtube.com/watch?v=ijG5rvEj228 Hurricanes are a truly terrifing storm.

//__The Forms Of A Hurricane__// There is only one form of this hazzard known as the terrifing Hurricanes. Hurricanes form in moist warm air in the trpics in the Atlantic ocean. Most hurricanes start of the west coast of africa and build up power over the atlantic. The hurricane orginally starts of as a thunderstorm often called tropical disturbances most die out but some do persevere and eventually reach there goal of becoming a hurricane. The rotation of the hurricane is formed by coriolis force which is a natural phenomonon which forces fluids to the right of there nothern hemisphere destination. Typhoons and cyclones are hurricanes but are caloled differently form were they started. // __The Atmospheric Conditions__ // The atmospheric condition in which a hurricane needs form in is warm moist air. That’s why they almost always form in the tropics. // __Where The Hazard Is Found__ // Hurricanes are a found in the Caribbean, Mexico and in southern America. But in the northern part of Asia are called typhoon and cyclones in south of Asia and the Indian Ocean .

//__What Are The Causes Of A Hurricane__// Hurricanes are caused when warm humid air rises. As the warm air rises the air starts to cool. When the air rises the water starts to condenses thus forming clouds. During the condensation process heat energy starts to release from the water thus creating the fuel for a hurricane.

Environmental Effect Caused By The Hazard__//**

//__The Environmental Benefits Of A Hurricane__// It may not seem real but between the destruction and horror of a hurricane. Hurricanes provide 25% of Americas rainfall alone this helps crops and plants to grow with eaise. They also wash away disease.

//__The Effects Of A Hurricane On The Environment__// The effects on the environment caused by a hurricane is unmistackble with oil spills and toxic waiste thrown up by a hurricane destroying plants, crops and harming animals. Hurricanes can cause erosion, flood crops and destroy not a tree but entire forests.

//__Specific Case Examples__// Eg (1):Fig 2 Areas affected South-eastern USA. Fig 3 : Location of New Orleans. Eg (2): Physical impacts Storm surges leading to flooding

Eg (3):Impact on humans - issues

1,500 deaths occurred in the states of Louisiana, Mississippi and Florida The impacts of Katrina is thought to have cost about $300 billion Thousands of homes and businesses were destroyed Thousands of jobs have been lost and millions of dollars in lost tax incomes to the affected states and USA federal government. Agricultural production was damaged by tornadoes and flooding. Cotton and sugar-cane crops were flattened. Three million people were left without electricity for over a week after the Hurricane struck. Eg (4): Theory What is a hurricane? Eg (5): Responses to Hurricane Katrina Responses discussion There were several responses to the Hurricane, both short and long term, in the south-east USA. For example, there was the immediate evacuation of hundreds of thousands of people. Some migration has become permanent as people have settled in other parts of the USA, for instance when peoples’ houses and businesses were permanently destroyed

food, weather and health || $81 billion dollars in damages occurred. It has been reported that 275,000 homes were lost as a result of the hurricane. More than 800,000 citizens were forced to live outside of their homes. ||  ||   || http://www.youtube.com/watch?v=FxgNuD5M9js&feature=related http://www.youtube.com/watch?v=yB33kPIhBkc&feature=related after effects of hurricane katrina.
 * Effects on rural and urban areas. || Wildlife officials in Louisiana, Mississippi and Alabama — the three U.S. states hit hardest by the hurricane — believe thousands of wild, farm and companion animals have perished due to storm surging and flooding from Katrina's heavy rains. Cattle, foxes, deer, raccoons, possums and household pets are among the animals that have died to hurricane katrina. It is reported that the American government will have to spend over $75 billion to relief from the hurricane. ||  ||   ||
 * Immediate effects on Housing,
 * Financial costs to rebuild homes. || State officials must understand that the $1.3 billion in available Community Development Block Grant funds wont be enough to fund the complete revival of the hurricane damages. ||  ||   ||
 * Hurricanes in America || America is hurricane prone area especially around the gulf of Mexico and the South - West coast of USA. In between 2000-2005 there have been 12 hurricanes around that area ||  ||   ||

__**WARNING SYSTEMS FOR HURRICANES IN USA**__

1) There is a website explaining how to prepare for a hurricane safely. It talks about what to pack, How to prepare your family and to be informed about the hurricane. http://www.ready.gov/america/beinformed/hurricanes.html. It is provided by Federal Emergency Management Agency. There are many different designs for hurricane proof houses. One of the most popular built hurricane resistant homes are the dome shaped houses. They are also storm resistant as well and I think the look pretty cool.

2) First of all if I had the choice I wouldn't live anywhere hurricane prone. But if I did live somewhere there I would spend a bit more for a hurricane resistant house. Also if there was a risk of a hurricane that I was informed about that was coming towards my area that I live in I would definantly leave early and pack.

3) The National Hurricane Centre are very helpful and inform places that are under threat for hurricanes. A major relief site for devastating hurricanes such as hurricane katrina is http://www.hurricanekatrinarelief.com/. There is a disaster response and assistance website called http://www.esri.com/services/disaster-response/hurricanes/index.html.


 * // 4) People shouldn't be able to build on the cost around the gulf of Mexico but I wouldn't know why you would want to live around there anyway if you know there is a risk of those kind of things. But people should build houses in the mainland even though there still is a chance that a hurricane will go there.
