为什么飓风几乎不会在赤道附近生成？
Why do hurricanes almost never form right at the equator?
旋转需要科里奥利力来启动，而赤道上科里奥利力为零，空气难以形成旋转的低气压中心，所以飓风一般在离赤道至少约 5 度以外才生成。
Spin needs the Coriolis force to get started, but it is zero at the equator, so a rotating low-pressure center can't form there; hurricanes need to be at least about 5 degrees from the equator.

台风（飓风）中间的“眼睛”为什么反而风平浪静？
Why is the 'eye' at the center of a hurricane calm and clear?
台风中心是下沉气流，空气从高空轻轻落下，所以风小、云少、甚至能见到蓝天，但四周的“眼墙”却是最凶的风雨区。
The center has sinking air that gently descends, so it's calm, clear, and sometimes blue-skied, while the surrounding eyewall packs the fiercest winds and rain.
