风眼 Eye (cyclone)

成熟热带气旋的横截面图,箭头代表空气在风眼内及其周围流动的方向。
温暖的海洋上空水汽冷凝时释放的能量将引发正反馈循环,从而形成热带气旋。

风眼是强烈热带气旋中心一片天气情况相对平静的区域,通常呈圆形,直径大多在30到65公里之间,其周围由风眼墙环绕,后者是一片环状的强烈雷暴区域,通常是气旋中天气最恶劣的地方。风眼中通常拥有整个气旋的最低气压,比风暴外的气压可以低出15%。

强烈热带气旋中的风眼通常云淡风轻,四面八方均环绕着密集、均匀的风眼墙。相对较弱的热带气旋中风眼界线较为模糊,并且有可能会被中心密集云区——一种高厚云层区域,在卫星图像上显示成亮区——掩盖。强度更弱或是组织结构紊乱的风暴中也可能存在风眼墙,但不足以完全闭合将风眼环绕起来,或是风眼区域内会出现豪雨。不过无论是哪种风暴,风眼都是气压最低的区域,并且又以接近海平面处气压最低。

Eye (cyclone) 风眼

(重定向自Hurricane eye)
An image of Hurricane Isabel as seen from the International Space Station showing a well-defined eye at the center of the storm.
A cross section diagram of a mature tropical cyclone, with arrows indicating air flow in and around the eye
Tropical cyclones form when the energy released by the condensation of moisture in rising air causes a positive feedback loop over warm ocean waters.
Typically, eyes are easy to spot using weather radar.  This radar image of Hurricane Andrew clearly shows the eye over southern Florida.

The eye is a region of mostly calm weather at the center of strong tropical cyclones. The eye of a storm is a roughly circular area, typically 30–65 km (20–40 miles) in diameter. It is surrounded by the eyewall, a ring of towering thunderstorms where the most severe weather occurs. The cyclone's lowest barometric pressure occurs in the eye and can be as much as 15 percent lower than the pressure outside the storm.
