摘要
为了解大范围气候变暖背景下铜陵地区气候变化趋势,选取铜陵近53年(1960—2012年)逐日气象观测资料,采用线性趋势拟合,结合滑动平均等统计量分析铜陵地区气候变化要素特征。结果表明:53年来铜陵年平均气温、年平均最高及最低气温均呈上升趋势,气候在变暖,其变暖幅度分别为0.20、0.19、0.24℃/10年,增温贡献最大的是最低气温。53年来年降水量呈略减少趋势,变化倾向率为-3.4 mm/10年;年平均风速随时间变化呈减小趋势,减小速率为0.33 m/s·10年;日照时数整体呈减少趋势,气候倾向率达-54.81 h/10年。
To understand climate change trend in Tongling under the background of a wide range of climate warming, select nearly 53 years （1960-2012） daily meteorological data to analyze element characteristic of climate change in Tongling by using linear trend fit combined with moving average.The results showed that nearly 53 years annual average temperature, annual average maximum and minimum temperatures presented a trend of increasing,climate was in warming,the warming rate were 0.20℃ per 10 years ,0.19℃ per 10 years ,0.24℃ per 10 years ,the biggest contribution for wanning was the minimum temperature.Annual average precipitation presented a trend of slightly decreasing, the change trend rate was -3.4 mm per 10 years; annual average wind speed presented a trend of deereasing, the reducing rate was 0.33 m/s per 10 years; sunshine hours showed a trend of decreasing as a whole, the change trend rate was -54.81 h per 10 years.
