downwind distance

常见例句

EIAA overestimates the concentrations at further downwind distance by more than a factor of 2.
对于下风向远距离处的浓度，EIAA的预测值高了一半以上。
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.
由于化学转换和衰减的作用，初生污染物随着下风距离而较快地减少，特别是在10公里以后的中距离上更加明显；
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.
发现由于垂直扩散较强，最大浓度常于近源处发生，且向下风方浓度衰减较快。
