Z-Depth pass was used to add some fog which really boosted the sense of depth in the images, separating the trees in the background from the foreground objects.

我们用Z-Depth路径增加了一些雾景，这确实增加了图像中场景的深度，将背景树木从近景中分离了出来。

The warm high ridge at the middle and low troposphere and the lower pressure of the ground all provide the good circulation background of this heavy fog.

对流层中低层的暖脊和地面均压场的维持是此次大雾形成的良好环流背景。
