摘要
文章基于高斯点源扩散模型,使用2022年1月六盘山自动气象观测站、激光云高仪、三维超声测风仪数据,对人工影响天气碘化银发生器生成催化剂在不同天气稳定度条件的水平、垂直范围扩散密度进行模拟研究。得出六盘山自动气象观测站人工影响天气作业-15~-25℃窗口高度在1.5 km附近,降水云层位置在1.6 km以下;催化剂有效密度103个/m ^(3)在强不稳定天气条件下垂直范围能达到4 km,水平范围能达到40 km;地面碘化银发生器生成的催化剂能够进入云层,密度能达到有效催化密度。研究结果可为六盘山区冬季地面碘化银发生器人工影响天气作业提供指导。
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.
