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 ro
A. The tropical waters are warm and calm.
B. The sea-surface temperature exceeds 27℃.
C. There are thunderstorms over warm tropical waters.
D. The atmosphere surrounding the sea is calm.

Hurricane is a name given to violent storms that originate over the tropical (热带的) or subtropical waters of the Atlantic Ocean, Caribbean Sea, Gulf of Mexico, or North Pacific Ocean east of the International Date Line. Such storms over the North Pacific west of the International Date Line are called typhoons (台风); those elsewhere are known as tropical cyclones (热带气旋), which is the general name for all such storms including hurricanes and typhoons. These storms can cause great damage to property and loss of human life due to high winds, flooding, and large waves crashing against shorelines. The deadliest natural disaster in the United States history was caused by a hurricane that struck the coast of Texas in 1990.
The costliest natural disaster in U.S. history stemmed from Hurricane Katrina in 2005.
