A hurricane is a fiercely powerful, rotating form of tropical storm that can be 124 to 1,240 miles in diameter. The term hurricane is derived from Hurican, the name of a native American storm god. Hurricanes are typical of a calm central region of low pressure between 12 to 60 miles in diameter, known as the eye. They occur in tropical regions. Over its lifetime, one of these storms can release as much energy as 10,000 nuclear bombs. The seed for hurricane formation is a cluster of thunderstorms over warm tropical waters. Hurricanes can only form and be fed when the sea-surface temperature exceeds 27℃ and the surrounding atmosphere is calm. These requirements are met between June and November in the northern hemisphere. Under these conditions, large quantities of water evaporate and condense into clouds and rain—releasing heat in the process. It is this heat energy, combined with the rotation of the Earth that
