Description of a Hurricane • A Hurricane is an extremely powerful, spiraling storm that starts near the equator. • There is a eye, which is the safest place in the hurricane, and the eye wall, which is the most dangerous place in the hurricane. (In land, but in sea, the eye is very violent) • There are at least three conditions for a Hurricane to be created; • The Ocean water needs to be 26 C to provide heat and moisture, the water vapor, into the overlying atmosphere to provide a fuel for the hurricane which is worked with a thermodynamic engine. • The water vapor must be combined with the heat and energy to form a powerful engine to make the hurricane twist and go. • A wind spiral pattern must be near the ocean surface to rise up. • After that, thunderstorms form, to make the air warmer and rise higher into the atmosphere. If this kind of wind is light, it can turn faster and get stronger, which is the beginning of a hurricane. Back to subtopics
Structure of a Hurricane. • This is a picture of the structure of a Hurricane. • While the wind is gathered, there is hole, and the center of the hole is the eye. The eye can be 3 km long until 370 km. The eyewall is where the wind surrounds the eye, and at the edge. Back to subtopics
Types of Hurricanes A hurricane can be called in 3 ways. In the Northern part of the Earth, it is called the name itself, a hurricane. A place near the Northwest Pacific Ocean is called typhoons. A place near Australia (Oceania), and the south of Earth, it is called Tropical cyclones. Back to subtopics
Names of Hurricanes Hurricanes are named after Tropical storms. If the tropical storm’s speed is over 63km/h, then they give them a name. And then, if the speed goes over 120km/h, they give the Hurricane the same name as the Tropical storm. For example, when a Tropical storm is named as ‘Tropical storm Min’, then when the speed gets over 120km/h, they name it ‘Hurricane Min’ Back to subtopics
How are the names named? The names are assigned by the National Hurricane Center. The reason is because they need to identify and explain to the people who were affected by the certain Hurricane. The “Giving names” started in 1953, by giving female names. However, from 1979, they started to name both male and female names. They rotate the names every six years, and then, every six years, they recycle the list unless, the name/s is/are “retired.” Back to subtopics
Tropical depression and Tropical Storm. Before the categories of hurricanes, there is something called tropical depression and tropical storm. Tropical depression- A stage before the tropical storm. When, thunderstorms combine, it becomes a tropical depression. Speed=37km/h-63km/h Tropical storm-When the tropical depression’s speed gets over 63km/h. The biggest damage given is rainfalls. Speed=63km/h-117km/h Back to subtopics
Strengths of a Hurricane. Back to subtopics
Hurricane Katrina Hurricane Katrina’s speed-280km/h pressure-902mbar Category:5 The total damage cost-$90.1billion (2010 USD) Fatalities-1,836 Start&end-August 23rd & August 30th 2005 Start&end place-Started from Southern part of Bahamas, and ended near Ohio. Place affected: Bahamas, South Florida, Cuba, Louisiana (especially Greater New Orleans), Mississippi, Alabama, Florida Panhandle, most of eastern North America. Back to subtopics
No. of Deaths Alabama-2* Florida-14** Georgia-2* Kentucky-1* Lousiana-1577***** Mississippi-238*** Ohio-2* Total:1836***** Missing:135 Back to subtopics
Economical effects $105 billion was used for repairs and constructions, however, this didn’t cover the oil spill which mostly occurred in the Gulf Coast. Katrina damaged or destroyed 30oil platforms and caused the closure of nine refineries. Mississippi was also affected, 5,300km^2 of forest lands were destroyed. The total damage cost $5 billion. In addition, extremely many people were left unemployed, which leads to less tax income to the government. All of the oil spills exceeded at least 10,000US gallons (38,000L) Total amount of oil spills: 7,205,440 US gallons, 27,294,900 L Which means that they lost a huge amount of money which they could make. The total loss of money for oil=$11,494,392 Back to subtopics
Environmental effects. The lands that were lost were the lands of marine mammals, brown pelicans, turtles, fish, and red head ducks. Overall, about 20% of the local marshes were permanently overrun by water because of the storm The water which flooded New Orleans were pumped into a river, and those water contained a mix of raw sewage, bacteria, heavy metals, pesticides, toxic chemicals, and oil, which made massive amount of fish die. This might’ve caused extremely serious medical problems. Back to subtopics
Crimes After the Hurricane, there were several crimes, so an armed troop were sent to stop the crimes. Then, it led to gunfights, between the troop*police and the residents. When they arrested all the criminals, they had to make a temporary prison at a train station since there were so many of them. Back to subtopics
Aftermath • This is the aftermath of Mississipi. Houses were destroyed and damaged. This is the aftermath of Louisiana, New Orleans. The whole place was flooded.
International aids. Over 70 countries helped the countries, especially New Orleans. They sent money, can food, water, and etc. The biggest donation made was $500 mil from Kuwait. Qatar and United Arab Emirates, each $100 mil. South Korea $30 mil, Australia $10 mil, India and China both $5 mil, New Zealand $2 mil, Pakistan, $1.5 mil, and Bangladesh $1 mil. Because of these donations, New Orleans could stand up again. Back to subtopics
