The article based on the Gaussian point source diffusion model and uses data from the Liupan Mountain automatic meteorological observation station,laser altimeter,and 3D ultrasonic anemometer in January 2022 to simulate the horizontal and vertical diffusion density of the catalyst generated by the silver iodide generator under different weather stability conditions.The artificial weather modification operation at Liupan Mountain automatic meteorological observation station has a window height of-15 ℃ to-25 ℃ around 1.5 km and a precipitation cloud layer position below 1.6 km.The effective density of the catalyst is 103 pieces per square meter,which can reach a vertical range of 4 km and a horizontal range of 40 km under strong and unstable weather conditions.The catalyst generated by the ground silver iodide generator can enter the cloud layer and reach an effective catalytic density.The research results can provide guidance for the artificial weather modification operation of the ground silver iodide generator in the Liupan Mountain area during winter.
