| 摘 要： | 利用常规气象资料和多普勒雷达资料,对2004年4月13日17时至24时发生在滇西、滇南和滇东南的大范围飑线天气过程进行分析,揭示了产生飑线天气的环流形势和影响系统,并从短期、临近预报角度对这次飑线天气过程归纳出预报指标,得出了飑线所引起的强对流天气的落区及各要素之间的关系,揭示了此次飑线的发生、发展和演变情况,以及飑线天气出现时天气和要素变化情况,为更好地提高预报飑线天气的准确率提供一定的参考.

| Abstract: | Based on the Doppler weather radar data and meteorological data,we have analysed the basic state of the squall lines that was in eastern Yunnan,western Yunnan and southern Yunnan during the period of 17:00 to 24:00,April 13th,2004.The results show that the squall line is occur under certain atmospheric circulation.Therefore,we have concluded many forecast standards which is about short term and extended weather forecast by analyzing the squall lines.Except this such conclusions can also be drawn as follows:... |
