Abstract：In this paper,test method of artificial seeding effect was studied based on an artificial catalytic ground work carried out in the Pinggu region of Beijing on August 23,2015 and the volume scan data per 6 min from the Beijing SA-band weather radar,seeding object was a local nascent meso-γ scale convective cloud.The resuhs showed it was appropriate that all units similar with work unit convection conditions was considered to contrast unit,and the non-parameter test method was used for effect test of small-scale convective cloud with short duration.For the maximum composite reflectivity,average composite reflectivity and echo area,the attenuation rate was obviously lower than contrast echo,so the work cloud life cycle is significantly larger than the natural cloud's,which indicated that the artificial seeding work had played an positive role in retarding attenuation,extending life cycle and maintaining development of the convective cloud.
