This text discusses how nonlinear clouds (NLCs) scatter sunlight more strongly in the forward direction than in the backward direction. It highlights that the disparity in scattering intensity between these two directions increases with larger cloud particles. This directional behavior has implications for understanding atmospheric optics and the visual phenomena associated with clouds, as well as their effect on solar radiation reaching the earth's surface.

NLCs scatter sunlight strongly in the forward direction, but only weakly in the backward direction. The larger the cloud particles, the larger the difference between the two directions.
