多普勒天气雷达在扑灭"7.29"井冈山火警中的应用

从多普勒天气雷达产品和天气形势分析入手,对利用人工增雨手段扑灭"7·29"井冈山火警过程进行了技术总结,得到了一些有益的结论一是井冈山区处副热带高压西南象限时,有利于人工增雨;二是中低空弱的冷平流有利于井冈山局部对流的发展;三是井冈山区对流单体在初始阶段的移向移速与700hPa风向风速对应较好;四是罗霄山脉中部的低空平均径向速度入流区的演变,与井冈山局部对流单体关系密切;五是应按山脉走向来布设人工增雨作业炮点.

Application Of Doppler Weather Radar To Stamp Out "7.29" Fire Accident Of Jinggang Mountain

The case of stamping out "7.29" fire accident of Jinggang mountain by artificial precipitation is analyzed and it follows : At first , it is fit for artificial precipitation stimulation when Jinggang mountain is in the south-western quadrant of subtropical high ; At second , the weak mid-level and low-level cold advection is of benefit to convection development over Jinggang mountain ; At third , the direction and speed of convective storm cloud is near to the wind in 700 hPa ; At fourth , convection development over Jinggang mountain is interrelated with the low-level inbound mean radial velocity on the middle of Luoxiao mountain ; At last , the spots of artificial precipitation stimulation should be disposed along the direction of mountain .
