摘要:

利用1961—2012年黑龙江省62个气象站逐日平均气温及日最低气温,定义黑龙江省单站寒潮,并着重分析了黑龙江省寒潮发生频次的时空变化特征。结果表明:近52 a黑龙江省寒潮频次明显减少,寒潮频次的多少与地形的分布特点一致,山区半山区等高寒地带发生寒潮的频次明显多于平原地区。寒潮在11月和12月发生的最多,9月最少,冬季的寒潮频次明显比春季和秋季多。近52 a春季、秋季和冬季寒潮频次基本为减少趋势,而大兴安岭地区秋季寒潮频次呈增加趋势。

关键词: 寒潮, 气温, 频次

Abstract:

Based on daily average temperature and the minimum temperature at 62 weather stations in Heilongjiang province from 1961 to 2012, cold wave at a single weather station was defined, and climatic characteristics of cold wave were analyzed. The results indicate that frequency of cold wave decreases significantly in recent 52 years, and it is in a good agreement with topography distribution. Frequency of cold wave is higher in the mountainous region than in the plain region. Cold wave appears mainly in November and December, seldom in September. Frequency of cold wave is higher in winter than in spring and autumn. Frequency of cold wave is in a decreasing trend in spring, autumn and winter in recent 52 years, except in autumn in Daxing’anling region.
