摘要
用地面烟炉开展人工增雨作业的关键环节是作业点附近的上升气流,利用海南省昌江霸王岭、东方玉龙山、乐东付光和五指山毛阳4个烟炉作业点附近的自动站和海口多普勒雷达资料并结合作业点地形特点对烟炉作业点布设条件和作业条件进行了分析,采用高斯模式对催化剂扩散情况进行了数值模拟。结果显示:这4个烟炉作业点均位于一定海拔的迎风坡,可利用上升气流将催化剂带入云中进行催化。综合利用NCEP/NCAR再分析资料、MICAPS资料和雷达数据确定作业时机,开展暖云烟炉人工增雨作业,增雨效果明显。
The key point of ground burner rain enhancement is the updrafts around the operation site.The layout conditions and operating conditions are analyzed with automatic meteorological station data from Bawangling of Changjiang,Yulongshan of Dongfang,Fuguang of Ledong,and Maoyang of Wuzhishan in Hainnan Province,as well as the Doppler radar data of Haikou,and the terrain characteristics of operation sites,and the catalyst diffusion is simulated using the Gaussian model.Results show that the four ground burners are on the high-altitude windward slope,where updrafts can take catalysts into clouds.By means of the comprehensive utilization of NCEP/NCAR reanalysis data,MICAPS data,and radar data to determine the operation time and to carry out the warm cloud seeding,the effectiveness of precipitation enhancement is obvious.
