How do hurricanes typically form and move

Explanation:Hurricanes are one of the most violent storms that occur on Earth. They are known by various names such as cyclones and/or typhoons,depending upon the location or place where they occur. However, the scientific term for all of these storms is tropical cyclone. Only those tropical cyclones that form over the eastern Pacific or the Atlantic Oceans are known as the "hurricanes". They form exclusively over relatively warm ocean water having temperatures of around 80°F or more warmer. and where the air cools off very quickly with height. Also, another important factor for the formation of a hurricane is that the wind must be blowing exactly at the same speed and in the same direction to force the air upwards from the surface of the ocean. A hurricane forms when a low pressure prevails over the oceanic surface and air from all of the surrounding areas with relatively higher air pressure gushes in to fill in this low pressure area. Then this "new" air that gushes, becomes relatively warm and moist and hence rises. As this warm air continues to rise upwards, the surrounding air then swirls in to take its own place. As this system of storm continues to rotate faster and faster, an eye forms in the process at the center. It is quite calm and clear in the eye, with a system of very low air pressure. Higher air pressure from the above then flows down into the eye and when the wind speeds reaches around 74 mph, the storm is officially known as a hurricane. Hurricanes dissipate if :

The temperature of the ocean/sea surface is colder than 80 degree Fahrenheit.

Sinking air from the regions of high pressure

the answer is c. altitude. hope this ! #brainiac
