風眼的形成:當熱帶氣旋到達一定的強度時,其中心附近之氣塊旋轉加快,環流中心的風速便很高。當因旋轉運動所引起的離心力和氣壓梯度力平衡時,中心便出形成了一個冇風冇雲的區域,此即風眼。緊密的螺旋雲帶就是圍繞著風眼旋轉 (北半球呈逆時針方向旋轉)。明顯的風眼通常只出現於颱風級的熱帶氣旋中心,風眼處氣壓最低,雲層稀薄而且風力微弱。但圍繞著風眼附近的還流卻是天氣惡劣,大風大雨的.
稀薄而且風力微弱。但圍繞著風眼附近的還流卻是天氣惡劣,大風大雨的.
為什麼風眼裏沒有風和平靜?
強烈的熱帶氣旋的環流中心是下沉氣流,將形成一個風眼。眼內的天氣通常都是平靜無風,無雲,甚至時有陽光(但海面仍可能波濤洶湧)。[4]。風眼通常都是呈圓形,直徑由2公里至370公里不等。[5][6]較弱的熱帶氣旋的風眼可能被中心密集雲層區遮蔽,甚至沒有風眼結構。
風眼分為無雲風眼和雲卷風眼
雲捲風眼是指熱帶氣旋的中心由螺旋雲帶旋捲而成,而缺乏俱有組織的風眼牆或中心雲團區。

Eye of wind formation: When the tropical cyclone arrives at certain intensity, nearby its center air parcel revolving speeds up, the circulation center's wind quick and efficient is very high. Because when the rotary motion causes when the centrifugal force and the barometric gradient strength is balanced, the center then left has formed a wind and cloud region, this was an eye of wind. The close spiral cloud belt revolves eye of wind revolving (Northern Hemisphere to assume counter clockwise revolving). The obvious eye of wind appears only usually in the Taiwan wind scale tropical cyclone center, the eye of wind place barometric pressure is lowest, the cloud layer is thin moreover the wind power to be weak. But revolves nearby the eye of wind also to flow is actually the stress of weather, the gale heavy rain.
Thin moreover the wind power is weak. But revolves nearby the eye of wind also to flow is actually the stress of weather, the gale heavy rain.
Why in the eye of wind doesn't have the wind and tranquil?
The intense tropical cyclone's circulation center is the submersion air current, will form an eye of wind. The intraocular weather is the flat calm usually, does not have the cloud, when has the sunlight (, but sea level was still possible mighty waves turbulently). [4]. The eye of wind is usually assumes the circular, the diameter by 2 kilometers to 370 kilometers different. [5][6] weak tropical cyclone eye of wind possibly by central crowded cloud layer area camouflage, even does not have the eye of wind structure.
The eye of wind divides into the non-cloud eye of wind and the cloud volume eye of wind cloud volume eye of wind is refers to the tropical cyclone the center to turn on lathe the volume by the spiral cloud belt to become, but lacks all the organized eye of wind wall or the central cloud cluster area.
