摘要
利用黑龙江省61个站1961～2006年冬季平均气温观测资料,首次采用月平均气温权重系数法确定了黑龙江省"冷""暖"冬的标准,分析了黑龙江省"冷""暖"冬的气候变化趋势和空间分布特征。结果表明:在1980年以后呈明显变暖趋势,冬季平均气温和暖冬指数的气候变率分别为0.568℃/10 a、13%/10 a,增暖高于全国平均水平;黑龙江省大部份地区冷暖冬权重系数指标的气候变率在0.4℃～0.8℃/10 a之间,山区大于相对较湿润的平原。
Using the average winter temperature data of 61 stations from 1961 to 2006 in Heilongjiang Province, Heilongjiang Province＂cold＂and＂warm＂winter standards were determined by monthly average temperature weight coefficient, and ＂cold＂and ＂warm＂winter of climate change trend and characteristics of spatial distribution were analyzed. The results showed that the winter of Heilongjiang Province generally got warming, and it had been a significant warming trend after 1980.The average temperature of the winter and the index of warm winter climate variability were 0.568 ℃/10 a,13%/10 a,and was highly warmer than the national average.In most areas of Heilongjiang Province, the climate variability of ＂cold＂ and ＂warm＂ winter weight factor were about 0.4 ℃-0.8 ℃/ 10 a, the mountainous area of that were higher than the moist flat land.
