| 摘 要： | 利用太白1960—2009年的气温资料,采用趋势系数、曼-肯德尔法、信噪比等对太白气温变化进行分析,结果表明：近50年来太白年平均气温呈显著上升趋势,其上升速率为0.32℃/10a,并且于90年代初发生突变。四季气温均呈明显或显著的上升趋势,以冬季气温上升最为显著,其次是春季;各月平均气温均呈上升趋势,以2月上升最为显著,其次是4月。

| Abstract: | Based on Taibai air temperature data during 1960-2009,using tendency coefficient,Mann-Kendall method,and signal-to-noise ratio,TaiBai temperature changes was analyzed in this paper.The average temperature showed significant rising trend nearly 50 years,with the rising rate at 0.32 ℃ per 10 years,and sudden change happened in early 1990s.The temperatures during four seasons showed the significant rising trend,especially in winter and spring.The average monthly temperatures were also rising,and the most significant increase was found in February,followed in April. |
