（单词翻译）

 An Atlantic hurricane often begins its life over the mountains in East Africa as an area of low pressure. It travels across the Sahara Desert, then moves out over warm ocean waters. Travelling with the trade winds and circles the globe just above and below the equator, these lows can spawn¹ thunderstorms over a broad region. They gradually come under the influence of the earth rotation² called the Coriolis Force and begin to spin. Satellites orbiting the globe begin to peer into them to watch for signs of intensification³, at the center, a region of low atmospheric⁴ pressure forms, known as "the eye." It acts like a partial vacuum causing winds at the sea surface to spiral inward toward it. These in-spiraling winds evaporate moisture from the warm ocean surface. As they near "the Eye," they rise rapidly, producing clouds and rain. Much of the air flows outward at the top of the storm like a chimney; soon flows back down into "the eye" itself causing the central zone to dry out and become clear.
