On January 22, 2018, an inverted trough was passing through the urban area in Xingtai where stratiform clouds were developed in low altitude.A particle measuring system mounted on King Air was used to complete and track the seeding operation.By comparing the microphysical variation of different-scale cloud particles before and after the seeding with satellite results, the artificial seeding was found successfully effective.After the seeding, the result response of target cloud is the key for the chain of evidence between precipitation augmentation and cloud seeding.When cloud condensation nuclei were rather uniform and the cloud was considered as one layer that a shallow cloud layer was formed, the cloud particles would grow homogeneously into supercooled water droplets with diameter between 4~6 μm, which would further form into the water cloud.The maximum liquid content was 0.2 g·m^-2.After the seeding, artificial ice nucleus consumed abundant supercooled water and further grew into ice crystals and ice crystal aggregations.The cloud particle concentration dropped from 200 cm^-3 into 15 cm^-3 because of the seeding, while for the same reason, the concentration of 100~1000 μm ice and snow crystals as well as the concentration of precipitation particles over 1000 μm increased to 150 L^-1 and 70 L^-1 respectively.Also, the presence of snowflakes with a diameter of 6000 μm showed the evidence of positive effect in facilitating snowing.Since the seeding area was targeting at cloudless or partly cloudy area, the dark cloud band was found in the Himawari-8 satellite cloud pictures along the seeding trajectory clearly proved the seeding operation with significantly effective results.
