And on the day that the tabernacle was set up , the cloud covered the tabernacle , the tent of the testimony ; and in the evening it was like the appearance of fire over the tabernacle until morning 15立起帐幕的那日,有云彩遮盖帐幕,就是见证的帐幕;从晚上到早晨,云彩在其上,形状如火。

Lighter particles provide a surface for cloud droplets to form . this leads to an increase in cloud cover , which , in turn , can lead to an increase in temperature since clouds have an insulating effect 较轻的微粒能够提供云滴形成所需要的界面,这样会增加云量,进而导致气温的升高,因为云有保温的作用。
Noon on april 10 , 1820 . dark clouds covered the sun . suddenly , the clouds burst and rain poured down out of the heavens . thunder and lightning filled the sky . pedestrians scattered , seeking shelter 1820年4月10日的中午,乌云遮住了太阳,忽然下起了倾盆大雨。天空中电闪雷鸣。行人都散开了,争相躲避。
A study using data on cloud cover taken from satellite images dating from 1979 found that 65 % of the world ' s skies were covered by cloud when cosmic rays were weakest and 68 % when they were strongest 研究从1979年起卫星云图所示云量的数据,发现宇宙射线最弱时,全球空中65 %的面积被云层覆盖;最强时这一数字为68 %
It is of course very useful for a migrating bird to be able to switch to a magnetic compass when clouds cover the sun ; otherwise it would just have to land and wait for the sun to come out again 具有这种磁场罗盘,对候鸟来说当然非常有用,因为如果乌云遮日,它可以以磁场为向导继续飞行,否则它就只好着陆,等待太阳重新出现。
2 . wavelet transform and conventional high - pass filtering method have been combined . using multiresolution analysis of wavelet transform , details of the result image after being removed cloud cover are greatly improved 将传统高通滤波和同态滤波的思想与小波变换相结合,充分利用小波变换的多分辨率分析,更好的保持了图像的细节信息。
In respect of clouds , while uv levels may be highest under cloudless skies , they can also be high with cloud cover . there have been instances of very high uv levels under broken clouds , which can enhance uv levels by reflection from their sides 就云的影响来说,在一般情况下它们会减弱紫外线,但亦有个案是由于零散云块的边缘反射而增加了到达地面的紫外线。
