INTRODUCTION
The term “hurricane” is a name given to violent storms that originate over the tropical or subtropical waters of the Atlantic Ocean, Caribbean Sea, Gulf of Mexico, or North Pacific Ocean. Hurricanes need warm tropical oceans, moisture and light winds above them in order to maintain themselves active. Those storms other than the ones considered typhoons are known as tropical cyclones, which is the general name for all such storms including hurricanes and typhoons. Hurricanes are named based on certain aspects and location of where they first originate. With just the right conditions lasting long enough, a hurricane can cause violent winds, incredible waves crashing against shorelines, torrential rains and floods that produce great damage to properties and human life.
HOW HURRICANES FORM
Tropical cyclones form and grow in warm ocean water as a collection of storms in the tropic, receiving their energy from latent heat. Hurricanes and other tropical cyclones begin as clusters of showers and thunderstorms. When one of these showers becomes organized with its winds making a complete circle around the center, a tropical depression is formed. “The deepening low-pressure center takes in moist air and thermal energy from the ocean while simultaneously the high pressure higher in the atmosphere pushes it outward” ( Longshore 1). As the clouds turn into a tight curl, the depression becomes a tropical storm. Due to low central pressure air spiraling cyclonically, the diameter of what is known as the “eye” of the hurricane is anywhere from ten to twenty miles. Hurricanes and tropical cyclones form, maintain their strength, and grow only when they are over ocean water that is approximately 27°C (80°F). This type of warmth causes large amounts of water to evaporate, making the air very humid. Since water is slow to warm up and cool down, oceans do not become warm enough for tropical cyclones to occur in the spring. When hurricanes...
