Global Warming And Hurricane Frequency and Intensity By Kristen Gardner

-a severe tropical cyclone, usually with heavy rains and winds moving at 74 miles per hour or greater What Is A Hurricane?

1- Warm Water 80 o F (27 o C) 2- Converging Equatorial Winds 3- Winds Flowing Outward 4- Humid Air Rising 5- Light Winds help it Grow *LATENT HEAT FUELS A HURRICANE (heat absorbed or radiated during a change of phase at a constant pressure) What Does A Hurricane Need?

Cross Section of a Hurricane Eye- Low Pressure Center that is Relatively Calm Eyewall- Most Violent Part of a Hurricane Rainbands- Feed the Hurricane in a Evaporation/Condensation Cycle

How Are Hurricanes Categorized? The Severity of a Hurricane is measured by the damaged caused.

Category 1-5  Category 1- Some damage to trees and non-anchored homes, including mild flooding.  Category 2- Considerable damage to trees, causing them to be blown down and more extensive damage to poorly anchored houses.  Category 3- Trees will be blown down, minor structural damage to buildings will occur and more severe flooding.  Category 4- Severe damage to roofing and houses, including damage to coast line structures, due to severe flooding  Category 5- Small buildings will be swept away as major structural damage occurs, resulting in the evacuation of all living near the coast due to disastrous flooding.  Category 1- Some damage to trees and non-anchored homes, including mild flooding.  Category 2- Considerable damage to trees, causing them to be blown down and more extensive damage to poorly anchored houses.  Category 3- Trees will be blown down, minor structural damage to buildings will occur and more severe flooding.  Category 4- Severe damage to roofing and houses, including damage to coast line structures, due to severe flooding  Category 5- Small buildings will be swept away as major structural damage occurs, resulting in the evacuation of all living near the coast due to disastrous flooding.

18 O is a natural isotope of oxygen and one of the environment isotopes and can be used to determine the temperature of precipitation though time. Interesting Fact: You can tell if an area has been effected by hurricanes by looking at tree rings.

???Global Warming??? What is really happening? Bottom Line The Climate has been changing since the dawn of time. What is really happening? Bottom Line The Climate has been changing since the dawn of time.

Global Warming is said to have started because of The Industrial Revolution, and the Greenhouse Gases that were a result of burning of fossil fuels. The change of CO 2 released into the air since the Industrial Revolution is around 60ppm, which isn’t enough to make that big of change. The same amount could be emitted by a volcano.

Global Warming = Less Hurricanes Global Warming appears to decrease the number of hurricanes in the Atlantic Ocean. If the planet warms, then it has been calculated that by the end of the 21st century: # of hurricanes in Atlantic will fall by 18% # of hurricanes reaching the USA and it’s Neighbors will drop by 30% # of the Biggest Storms will fall by 8% # of Tropical Storms will decrease by 27% Global Warming appears to decrease the number of hurricanes in the Atlantic Ocean.

This Sums It Up?

Katy Perry’s song says it all “Your HOT then your COLD” There is always going to be a book or article that will tell you what ever it is you want to hear, the climate change debate is no different.
