If you reading this article then you most likely is familiar with Hurricane Katrina, one of the most deadly, strongest and costliest hurricane that made landfall on the coast of the United States way back in 2007. It was considered a category three hurricanes based on the Saffir-Simpson Scale with wind speeds up to 125 miles per hour. Needless to say, Hurricane Katrina destroyed homes, livelihood and killed countless lives when it entered the United States.
What exactly is a hurricane? What makes it different from a typical cyclone or storm? Well, to start, a hurricane is a tropical cyclone with winds over 74 miles per hour. Storms can also serve as precursors for a hurricane. It starts as a tropical depression and into a full sized wind powerhouse when the conditions are right. Hurricanes initially form over warm ocean waters and when it this land, it pushes sea water along which what is called a storm surge. There are three things needed for the perfect hurricane to form. As described earlier, the sea water should be warm to create layers of heat and moisture which serves as the power source of what a hurricane becomes. For a hurricane to move, it requires the atmospheric moisture from the water evaporation to combine with the heat which moves the hurricane to a specific direction. Lastly, the wind patter should move around to form spirals of air. This reaction causes the wind to grow stronger, making it rise higher and more powerful.
Hurricanes have five categories. Hurricane Katrina was a category three hurricane but there are two more categories above that which are far more powerful and surely will cost big time damage when it hits land. To start, a category one hurricane has speeds that around 74 miles per hour, that is faster than a prime cheater at full speed! A category two has around 96 miles per hour of winds and a three have around 111 miles per hour of winds. A category four has around 131 miles per hour which is a fast as the fastest roller coaster in the world. Finally a category five hurricane has winds as fast as those high speed trains found in Europe and in China.
Katrina might be the strongest, fiercest hurricane to hit the United States recently but a far more deadly hurricane hit Galveston some hundreds of years ago. It took 6000 to 8000 lives and one of the most powerful natural disasters in American history.
