cirrocumulus 中文意思是什麼
cirrocumulus
解釋
卷積雲-
Under the influence of atmospheric waves which are often present at high altitudes, the clouds line themselves up and move with the upper level winds, forming the cirrocumulus clouds having a fish - scale appearance
雲朵受高空波狀氣流所影響，組成行列，並隨著高空的風向飄移，形成魚鱗一樣的卷積雲。 -
Mackerel sky, not twenty - four hours dry describes the deterioration of weather after the appearance of cirrocumulus clouds. although it may be bright at the beginning, the weather will deteriorate in half a day s time as the cyclone or front approaches. as they pick up more moisture, the cirrocumulus clouds thicken and extend downward to become low - level clouds which bear rain
魚鱗天，不雨也風顛是形容卷積雲出現後天氣轉壞的狀況，雖然初時天氣明朗，但約半天光景后，天氣會隨氣旋或鋒面的移近而轉壞，風速增強，卷積雲也會隨著水氣增加而逐漸增厚，雲層向下伸延轉為低層雲，產生降雨。 -
In meteorology, they are called cirrocumulus clouds
氣象學上稱這種雲為卷積雲。 -
Cirrocumulus clouds are high clouds, generally with a cloud base at above 6000 metres where the temperatures are several tens of degrees celsius below zero. they are composed of tiny ice crystals and are thin and translucent
卷積雲屬于高層雲種，雲底高度一般在6000米以上，溫度是攝氏零下數十度，雲朵全部由細小的冰晶構成，薄而透光性高，看起來有蠶絲般的光澤。 -
The occurrence of cirrocumulus clouds indicates the distant presence of a convergent zone such as a pressure tough or a cyclone in lower levels ; or a frontal zone where cold air meets moist warm air. vigorous convection and lifting motion bring water vapour up in the sky where the water vapour sublimes into ice crystals, forming the high clouds
卷積雲的出現顯示遠處地方低層有一強輻合帶如低壓槽或氣旋或鋒面即暖濕空氣碰到冷氣團，向上爬升的交界面形成，強烈的對流和抬升運動將水汽帶到高空，在那裡水汽直接升華變為冰晶而形成高層雲。
