| atmospheric circulation (The general movement and circulation of air, which transfers energy between different levels of the atmosphere. The mechanisms of circulation are very complicated. They involve the transfer of energy between the oceans and the atmosphere, the land and the atmosphere, as well as the different levels of the atmosphere) |
大气循环 |
|
| atmospheric component (The Earth's atmosphere consists by volume of nitrogen (79,1%), oxygen (20,9%), carbon dioxide (about 0,03%) and traces of the noble gases (argon, krypton, xenon, helium) plus water vapour, traces of ammonia, organic matter, ozone, various salts and suspended solid particles) |
