we use a spectral model for the medium-range numerical weather forecast to discuss the impact of the diurnal variation of solar radiation on the medium-range weather processes. Under the tests of two typical winter and summer cases;
we find that the influences of the diurnal variation of solar radiation on summer weather are really important;
especially on its rainfall;
surface heat transport and 500 hPa height field. On winter weather;
however;
the influences are very weak.;
