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
Hurricanes form in the open ocean, with the majority coming together in the western Pacific Ocean or the eastern Atlantic, off the coast of Africa. A smaller number form in the Gulf of Mexico or the Indian Ocean each year. Hurricanes require calm, warm ocean waters to set up the convective current that gives the storm its rotational power and allows it to build into a powerful cyclone.Full Answer >
Hurricanes are dangerous because they have high winds, torrential rains and storm surges. Individually, these dangers can pose a threat to one's life and damage property, but they can cause widespread destruction when the forces are combined.Full Answer >
Hurricanes end when they lose their source of energy, often by traveling over land or over cold water. Hurricanes require a steady supply of warm, moist air to fuel the rotation that keeps the storm coherent, and when that source is cut off, the cyclone quickly uses up what energy it has and dissipates.Full Answer >
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 >
