高空气象资料在天气现象中的应用分析

Application Analysis of High-Altitude Meteorological Data in Weather Phenomena

文章利用探空资料分别计算露点温度、K指数、沙氏指数、抬升指数等物理参数,并且对长沙市的冰雹、雷暴和稳定降水进行分类分析,结合统计学方法分析各物理参数与降水预报之间的相互联系,归纳出适合于长沙市降水潜势预报的探空指标,提高长沙市强对流天气的预报预警能力。

In this paper, using sounding data, physical parameters, such as dew point temperature, K index, S index and uplift index were calculated respectively, and hail, thunderstorm and steady precipitation in Changsha were classified and analyzed. The correlation between physical parameters and precipitation forecast was analyzed by statistical methods, and the sounding index suitable for precipitation potential forecast in Changsha was concluded, in order to improve the forecast and warning capability of severe convective weather in Changsha.
