Transcript of Hurricanes
hurricanes usually start of in clusters of clouds. hurricanes also start of as thunderstorms called tropical disturbances the rotation of a hurricane is from the corolis force.some of these tropical disturbances lead to hurricanes and some do not.when a tropical disturbance turns into a hurricane it releases latent heat. latent heat warms areas in the disturbance. latent heat causes air density which causes wind speeds to increase. sometimes the coriolis force is too weak to help form hurricanes.
Hurricanes actually rotate in different directions depending on where its located. In the Northern Hemisphere, hurricanes rotate counter clockwise. In the Southern Hemisphere, it rotates clockwise.
The first name of the hurricane in the year 2014 will be one that starts with an a. So that means beacuse one only one name starts with an a this year, the name will be Arthur.Did you know that some hurricane's names are retired? In the past, hurricanes caused catestrophic destruction that there will never be a hurricane that will fit that name again. Retired names include: Georges, Mitch, Floyd, Lenny, and Keith.
A Flash in the Past
Hurricane Irene hit 2011 from August 21st to August 30th with winds up to 120 mph. Hurricane Irene is what Nick would refer to as a Category 3 hurricane. On August 21st, Hurricane Irene started out as a category 1 Hurricane, only between 74-95 mph. Later that day, before it reached the Bahamas, Hurricane Irene gathered more power and turned into a Category 3 hurricane. Hurricane Irene mainly affected the Caribbean and the East Coast of the United States. Did you know that Hurricane Irene was ranked as the seventh-costliest hurricane in U.S. history? This hurricane caused $16.6 billion of damage and at least 56 deaths.

Fun facts about hurricanes
-The word hurricane came from Taino Native American word, hurrucane. It means the evil spirit of the wind.
-Normal hurricanes can dump 6in.-1ft. of rain across a region.
-Hurricanes can produce weak tornadoes (they only last a few minutes)
-Jupiter has a hurricane that's been going on for over 300 years. You probably know it as its red spot.
-Slow moving hurricanes produce more rainfall
Fun Facts Continued
-All hurricanes begin life in a warm, moist atmosphere
-Hurricanes are the only weather disasters that have their own names
- The first time anyone flew into a hurricane was in 1943
Storm Surge by Nick
I hoped you liked our prezi on hurricanes and now know how to stay safe and being able to tell what category of a hurricane it is. What do you know? Maybe a hurricane is on its way. :)
The center of the hurricane is called the eye because this part of the hurricane is usually totally calm. The calm center of the hurricane is directly surrounded by the eye wall. the most violent wind speeds are at the edge of the core. the scales that is used to rate hurricanes is the saffir-simpson hurricane scale. category 3 produces a storm surge of 9-12 feet
During a hurricane, the effects of a storm surge on a coastal area is very strong. The surge is often 50 miles wide and acts like a bulldozer knocking anything down that gets in its way. If the hurricane is really strong, the strom surge will be very high. Many people think that storm surges are the most hazardous things that come out from a hurricane but, hurricanes also cause floods and strong winds.
In the US Hurricanes are many sizes in betweeen 100-200 km. Did you know that normally, the hurricanes on Northwest Pacific ocean are bigger than the ones on the Eastern Pacific ocean. People also measure the size of hurricanes by the radious of isobar. Finally, people determind size on the wind speed the hurricane is going and puts it into categories like Nick mentioned.
- Hurricanes are also called cyclones, typhoons and tropical storms.
-Hurricanes normally form in tropical areas of the world.
- Costal regions are at most danger from hurricanes.
- Hurricanes lose strenght as they move over land
