中文摘要: 利用常规气象资料、MICAPS资料和NECP/NCAR再分析资料，结合高斯模拟，分析了2012年11月10日唐县大茂山地基碘化银发生器增雪作业的作业条件。结果发现，此次天气背景为自西南向东北移动的冷涡云系，根据帕斯奎尔（Pasquill）稳定度分类法得出作业时间段大气处于中性层结状态；高斯模式模拟得出，有效的AgI浓度向上扩散范围高达3.0 km；作业点作业时段上空至3.2 km均处于上升气流区，计算出作业点发生器出口温度1.0℃。因冬季人工观测云底高度多为2.5~3.0 km，综合分析认为，该作业点的选址是合适的，此次作业条件较好，可以将催化剂输送到云中，起到催化作用。

Abstract:Based on conventional observational data, MICAPS data and NECP/NCAR Reanalysis data, together with the Gaussian simulation method, snow enhancement operation conditions on 10 November 2012 by the ground based silver iodide (AgI) generator over Mountain Damao of Tangxian were analyzed. The result showed that the weather condition is cold vortex system moving from southwest to northeast. According to Pasquill stability classification, the atmospheric stratification is neutral during the operation process. The Gaussian simulation results showed that the effective concentration of AgI can diffuse up to 3.0 km. Moreover, the atmosphere is in the updraft from the surface to 3.2 km through the operation procedure. The atmospheric temperature at the height of the generator outlet is 1.0℃ by calculation. The cloud base height in winter by manual observation is between 2.5-3.0 km. Therefore, it is concluded that the position of operation site is appropriate and the operating conditions are suitable to deliver the AgI catalyst to the cloud as well.
