摘  要:
[目的]研究近50年苍山冬季的气温变化特征。[方法]选取1961~2010年苍山地面气象观测站冬季气温资料,采用相关性系数、Fisher最优分割法、5年滑动平均等统计分析方法,探讨近50年苍山冬季气温变化特征。[结果]从1961年以来,苍山县冬季平均气温、最低、最高气温均呈波动式缓慢上升趋势;从20世纪90年代中后期冬季气温开始明显跃升,正距平出现频率增加了3.5倍。[结论]苍山地区50年来的气候变化趋势与全球气候变暖的背景相一致。

摘  要:
[Objective] To study the variation characteristics of winter temperature in Cangshan.[Method] According to the ground meteorological observation data in Cangshan during 1961-2010,the winter temperature changes of Cangshan in recent 50 years were discussed using correlation coefficient,Fisher optimal partition method,5 years average and statistical analysis method.[Result] Since 1961,the average,maximum and minimum winter temperature showed fluctuating slow ascendant trend.In the later period of 1990s,the winter temperature started to jump,and the positive anomaly frequency increased 3.5 times.[Conclusion] The climate changed consistently with the context of global climate warming in Cangshan in latest 50 years.
