影响首都机场的一次雷暴过程的红外云图和闪电分析

SHALLOW DISCUSSION ON SOME PROBLEMS OFPOLLUTION AND ITS CONTROLLING OF ATMOSPHERICENVIRONMENT OVER THE LANZHOU CITY

利用卫星云图和闪电资料对１９９４年８月２日影响首都机场的一次雷暴过程进行了详细的分析。结果表明，这次雷暴过程中有３个中尺度对流系统的发生和发展，因而对首都机场的影响持续了约５ｈ。闪电资料的分析表明，闪电活动的位置、频率和极性与对流系统的发展阶段有关。因此，除了每小时一次的卫星云图外，即时的闪电观测资料也是预报中尺度对流系统很有用的工具。

In this paper,the physical mechanism and objective cause of formation of atmospheric pollution over Lanzhou city are analysed. And the methods and measures which are being adopted or demonstrated for controlling atmospheric pollution at present are summarized,analysed and discussed. Then,the several problems which need studing as focal point are pointed out. Finally,the preliminary views and proposals about controlling atmospheric pollution of Lanzhou city are suggested.
