摘要
利用武穴国家气象观测站1959—2018年地面气象数据资料,采用回归分析、趋势线分析、距平分析等方法,对近60年武穴市气温和降水变化特征进行分析。结果表明,近60年武穴市平均气温17.1℃,气温倾向率为0.143℃/10 a,年平均气温总体呈上升趋势;春、冬季增温显著,秋季次之,夏季略有下降;气温年代际变化明显,逐渐进入偏暖期。近60年武穴市年平均降水量1427.9 mm,降水倾向率为15.082 mm/10 a,降水年代际波动较大,总体呈上升趋势;四季降水倾向率分别为-4.051、16.268、-1.507、4.372 mm/10 a;春、秋季降水呈下降趋势,夏、冬季降水呈上升趋势。
Using the ground meteorological data of Wuxue National Meteorological Observatory from 1959 to 2018,regression analysis,trend line analysis and anomaly analysis were used to analyze the variation characteristics of temperature and precipitation in Wuxue City in the past 60 years.The results showed that the average temperature of Wuxue City in the past 60 years was 17.1℃,the temperature tendency rate was 0.143℃/10 a,and the annual average temperature was generally rising.The temperature increase in spring and winter was significant,followed by autumn and slightly decreased in summer;the interdecadal temperature change was obvious and gradually entered a warmer period.In the past 60 years,the average annual precipitation in Wuxue City was 1427.9 mm,and the precipitation tendency rate was 15.082 mm/10 a.The inter-decadal fluctuations of precipitation were relatively large,and the overall trend was upward.The trending tendency of precipitation in the four seasons was-4.051,16.268,-1.507 and 4.372 mm/10 a,respectively;precipitation in spring and autumn showed a downward trend,and precipitation in summer and winter showed an upward trend.
