    The multi-level nonlinear balanced ω-equation is used to study the Mei-yu from June 29th to July 12th of 1991. The results show that the distribution of the vertical velocity calculated this e-quation can reflect the position of the rain belt properly. The stable condensation heating is the most important factor to the maintenance of the storm rainfall during this period. The horizontal advection of the vorticity is less important than the thermal advection. But the normal advection of the vorticity is important. During this period, the effect of convective condensation heating is very weak.

    It was introduced that the methods of converting all kinds of data from different coordinates systems. Also the error of data transformation was discussed. These kinds of data are satellite data,radar data, conventional sounding data, automatic meteorological station data, flash detection data and remote sensing data in Beijing-Tianjin-Hebei Experimental Base of Mesoscale Meteorology.
    3  A Simple Calculation of Diurnal Variation of Ground Surface Temperature Field in the Hilly terrain
    李慧 翁笃鸣
    1993, 19(1):14-17. DOI: 10.7519/j.issn.1000-0526.1993.01.003

    Based on the simulation test and observation of ground surface temperature and total radiation on the hillside,a regression equation is obtained. The results show that the distribution of the calculated ground surface temperature is consistent with the feature of hilly terrain, and the variations of the ground surface temperature lags behind that of total radiation.
