| 摘 要： | 利用东北地区1971-2006年43个气象台站大风、气温以及全球气温资料,采用线性趋势分析、滑动T检验和Yamamoto法、差值T检验等方法分析了东北地区大风的多时间尺度和空间的气候变化特点、变化趋势、突变特征及其与全球气温、东北地区气温变化的关系。结果表明,东北地区大风气候趋势为显著下降趋势,气候倾向率为-12.3 d/10 a,且在1988年发生了气候突变,由大风偏多期转为大风偏少期。东北地区大风与全球气温、东北地区气温变化呈相反的变化趋势,大风偏多期与冷期相对应,大风偏少期与暖期对应,东北地区大风由多转少与东北地区气温由低转高同步发生。

| Abstract: | The data of strong wind and temperature as well as global temperature during 1971 – 2006 of 43 observation stations in Northeast China were utilized,and the methods of linear trend analysis,slide t detected,Yamamoto and D-value t detected,etc.were adopted to analyze the climatic change characteristics,climatic trend and abrupt change of climate of strong wind from the angle of multi-time scales and space in Northeast China,and their relationship with global climate,climatic change in Northeast China.The results indicated that the climatic trend of strong wind in Northeast China showed decreasing tendency obviously,the climate tendency was-12.3 /10 a,however,abrupt change of climate happened in 1988,namely,the strong wind transformed into less frequency period from more frequency period;the strong wind in Northeast China presented the opposite change tendency compared with global temperature and temperature variation in Northeast China,more frequency period of strong wind was corresponded with the cold period,and less frequency period of strong wind was corresponded with the warm period,and from more frequency to less frequency of the strong wind was simultaneously occurred with temperature from low to high in Northeast China. |
