【文　　摘】By use of the daily data of severe local storm in Beijing area and Beijing's sounding from April to September of 1980-1988, the favourable conditions for the storm genesis are identified. They are (1) low pressure in the lower troposphere, (2) unstable stratification in the troposphere and potential instability in the middle-low troposphere, (3) high vapour content in the lower troposphere and large relative humidity in a deep tropospheric layer. The storm genesis is independent of strong wind in high troposphere, vertical wind speed shear and dryness in the middle troposphere.
