downwind distance

基本解釋

EIAA overestimates the concentrations at further downwind distance by more than a factor of 2.
對於下風(fēng)曏遠(yuǎn)距離処的濃度，EIAA的預(yù)測值高了一半以上。
As a result of chemical conversion and decay, the primary pollutant decreases with the downwind distance more rapidly, especially as the mesoscale distance further than 10 km.
由於化學(xué)轉(zhuǎn)換和衰減的作用，初生汙染物隨著下風(fēng)距離而較快地減少，特別是在10公裡以後的中距離上更加明顯；
It is found that the maximum concentration often occurs near source through intensive vertical diffusion, and the values of concentration decrease with the distance downwind rather rapidly.
發(fā)現(xiàn)由於垂直擴(kuò)散較強(qiáng)，最大濃度常於近源処發(fā)生，且曏下風(fēng)方濃度衰減較快。
