The characteristics of a cold-front cloud during the forest fire on April 17,2011 in Funing county of Hebei province,were analyzed at macro and micro scale.Meteorological data of conventional observations,satellite cloud image,Doppler weather Radar data,aircraft observation,and the NCEP reanalysis data were used to analyze the precipitation enhancement potential of this cold-front cloud.Macroanalysis shows that the water vapor carried by the cold-front cloud is the only source of the artificial precipitation enhancement,which is small in moisture convergence thus not favorable for precipitation.Microanalysis shows that relatively thin supercooled water area exists in both horizontal and vertical direction of the cold-front stratiform cloud system,with certain proportion of small particle concentration>20 cm^-3 in size.After the feeding operation,the radar echo intensity is enhanced,parameters of the particle concentration,LWC and the mean diameter of particles detected by CAS change significantly.Results show that the cold-front cloud has certain precipitation enhancement potential.
