Storms classified as hurricanes generally originate in the tropical latitudes of the northern Atlantic Ocean and the Pacific Ocean east of the International Date Line. Tropical cyclones west of the International Date Line in the northern Pacific are called typhoons, and those that originate in the Indian Ocean or southern Pacific Ocean are simply called cyclones.Know More
Hurricanes and other tropical cyclones tend to form in the tropical latitudes because these storms need access to warm, calm water to form. The warmth provided by these waters heats the air above the ocean's surface, causing it to rise. The rising air deposits clouds to the upper atmosphere and creates a low-pressure zone, and the air flowing into this depression triggers the rotation that creates a tropical cyclone.
Most hurricanes that form in the Atlantic Ocean track westward toward the Caribbean Sea, turning north at some point. They may work their way into the Gulf of Mexico and hit the southeastern Unites States, or they may travel up the eastern seaboard. In some cases, hurricanes can form in the Gulf of Mexico or western Caribbean Sea. Pacific hurricanes tend to form off the western coast of Mexico and travel either westward into the ocean or northwest up the coast toward California.Learn more about Storms
According to NASA, approximately 85 hurricanes occur worldwide each year. Not all of these hurricanes are devastating; some of them appear to be ordinary storms for the most part and only develop into official hurricanes for a few short hours, whereas others can be considered full-force hurricanes for several weeks. In order to be considered an official hurricane, in addition to having an eye with low atmospheric pressure, the circulating wind speeds should exceed 74 miles per hour.Full Answer >
According to NASA, hurricanes form when warm, calm ocean waters create a rotating convection current in the air above the surface. As the warm, humid air rises, it creates a cloud layer in the cooler regions of the atmosphere, and surface winds blow into the low pressure center. Over time, this air circulation may cause the clouds to rotate, allowing them to draw more moisture and energy from below.Full Answer >
Hurricanes are made when tropical storms form over sections of the ocean with warm, moist air and enough wind to begin a spiral. The primary cause is the latent heat from water evaporating off the surface of the ocean, which causes atmospheric imbalances that can increase wind speeds to hurricane levels. These can be higher than 150 miles an hour around the hurricane's eye.Full Answer >
Hurricanes form over the Atlantic or Pacific Ocean near the Equator when the surrounding water is at least 80 degrees Fahrenheit, according to SciJinks. The term "hurricane" typically refers to tropical storms in the Western Hemisphere, but similar weather conditions occur worldwide and are known as tropical cyclones or typhoons.Full Answer >
