Real-time simulation of volumetric cloud is an important part for improving fidelity of virtual reality natural environment.

The main effect of them is to heat the lower troposphere, but cool the surface, so the presence of dust may cause a stabilizing effect on the temperature lapse rate, then affect the ocean low level stratus cover.

A Study of Macro-and Microscopic Features and Precipitation Mechanism of Spring Precipitating Stratiform Clouds in Henan Province;

physico-chemical model of stratiform clouds is used to evaluate the acidification of precipitation and wet removal of pollutants in South China in spring season and results from the model are consistent with the mean field data.

First,the original image is decomposed with wavelet,ratio edge detector is adopted to get the edge direction of manmade targets and Frost filter is performed in the direction,thus efficiently restraining cloud noise and strengthening the manmade target and its edge information at the same time.
