| 摘 要： | 采用文山州8个气象观测站1980～2008年近29 a 11月～次年4月的日平均气温、最低气温、各县寒潮气温临界值Tk等资料,计算出24h及48h降温幅度,根据云南省气象局制定的全省寒潮标准,结合文山州的气候特点,找出符合文山州寒潮标准的寒潮天气过程,并统计分析这29 a来全州8站寒潮的时空分布、强度、路径等特征.统计中发现,每个站点寒潮出现的频率不仅与站点的位置有关,还与站点的海拔高度有一定的对应关系;寒潮天气出现的频率,呈逐年下降的趋势;寒潮出现前1～2 d,其各层关键区内,会出现相应的指示性变化.找到这些特征,对做好文山州寒潮的预测预报有着重要的参考价值.

| Abstract: | To calculate the 24 hours and 48 hours of cooling rate,meteorological data(the daily average temperature,minimum temperature,cold temperature threshold Tk) from 1980 to 2008 of 8 stations of Wenshan were used.according to the cold weather bureau standards of Yunnan province and the climatic characteristics of Wenshan,we found the weather process according with the standards,and analyzed the statistical characteristics of the cold at the state's 8 stations,such as the temporal and spatial distribution,intens... |
