Perfect Condition

If you've ever wondered why hurricanes arrive like clockwork during "hurricane season" is because the conditions are perfect. With the warm waters summer, low pressure systems, and other conditions in place, hurricanes are born.

Hurricanes begin as low pressure weather systems over Africa and emerge as tropical disturbances over the warm waters of the Atlantic Ocean during summer and early fall. The humidity and heat energy these low pressure disturbances, creating thunderstorms. Some thunderstorms dissipate and that is the end of the story. However, the strength of many collection and wind speed. When these storm systems continue to develop and winds have reached 40 miles per hour, which are designated as a tropical storm and given a name in the center National Hurricane Center. Once a storm is called, it is not necessary for becoming a full-fledged hurricane. In fact, many tropical storms fizzle out. Other intensify, continuing to energy from hot springs and wet, while cooler ventilation below, dry air above. The energy is released heat and strong winds on the form. Meanwhile, the center of the storm heats up due to the release of energy and water vapor, causing a pressure drop air and stronger, more intense winds in the nucleus. This creates a cycle of more heat, continuous low pressure and strong winds.

By Finally, if winds reach 74 mph, tropical storm becomes a hurricane category. Hurricanes can vary in intensity, up and down Saffir-Simpson scale as they lose or gain intensity. For example, when hurricanes reach land, they quickly weaken because they are no longer fueled by warm waters. However, many move on earth, back to the open waters where they quickly regain their lost strength.

The hurricanes are category one the least destructive with winds ranging from 74-95 miles per hour. The uprooted trees, damaged bushes, and damaged mobile homes are the typical victims Category One hurricane.

Category Two hurricanes have winds ranging in speed from 96-110 miles per hour and usually cause storm surges of 6.8 feet above normal. The function category three hurricane winds of 111-130 mph and storm surges 9.12 feet. Category Four hurricanes are characterized by the speed of the winds of 13-155 mph and storm surge 13-18 feet above normal. Finally, Category Five hurricane winds over 156 miles per hour and storm surges over 18 feet.

Obviously, as hurricanes work their height scale, with winds and larger storm surges, the potential damage increases dramatically. Only a few category five hurricanes have hit land in the U.S. However, lower rated Hurricanes can wreak havoc when conditions are right. Hurricane Katrina, the most devastating hurricane that hit the United States, came ashore as a Category Three hurricane.

While hurricanes are destructive as far as man and civilization are concerned, have beneficial qualities. One, which provide up to one quarter of the annual rainfall in the southern states and may even play a vital role in maintaining heat balance of the Earth – moving heat from the tropics toward the poles. Hurricanes have a long-term positive effect on marshes and coastal wetlands, as well as storm surges adding essential nutrients and sediments of these fragile lands. Under the sea, coral benefits of hurricanes as well. For example, cooler waters move to the surface, to counter "whitening" effect warm water. In addition, some species of corals, including elkhorn coral, reef break and reattach elsewhere, forming a new reef. Though capable of extreme destruction, hurricanes help build barrier islands which in turn provide the first line of defense against the fury of the hurricane.

Warm ocean waters, coupled with tropical disturbances and low pressure systems each summer and fall provide the ideal setting for a hurricane to form. Whether a tropical depression progresses to a tropical storm or hurricane depends on the conditions at the time. As summer approaches fall, these conditions are perfect for a storm.
