摘要
利用 1 971～ 2 0 0 2年湖南省 95个站的冰冻资料 ,统计分析了 33年来湖南冰冻资料并进行了分类研究 ,概括了近 30多年来湖南省冰冻出现的频率以及时间和地理分布规律。从而总结出湖南冰冻天气的地形、年代分布特征 ,在此基础之上 ,还系统分析了历年来持续最长的冰冻天数的分布特点。
Based on the frost data collected by Hunan 95 observation stations from 1971 through 2002, the dates that the frosts began and ended are analyzed statistically. The total days, locations and durations that frost appeared monthly in the past years in Hunan are studied, respectively.The statistical frequency, time and geographical distribution of frost in Hunan in the recent 30 more years are presented.
