| 摘 要： | 本文利用1906-2015年武汉月平均最高与最低气温资料,重建了过去110年武汉市年平均气温距平序列,分析了其年代际尺度的变化特征。主要结论为：①过去110年武汉市经历了“暖—冷—暖”3个多年代际波动,其中1906-1946年与1994-2015年气候相对温暖,1947-1993年则气候相对寒冷;②在多年代尺度上,武汉市存在多次显著增温和降温过程,其中增温速率最快的30年和50年分别出现在1980-2009年和1960-2009年;最快降温速率则出现在1928-1957年和1925-1974年;③过去110年武汉市年均温发生了3次跃变,其中由冷转暖的跃变出现在20世纪20年代初和90年代中后期,而由暖转冷的跃变则出现在40年代;④武汉市年均温变化与全球/北半球和中国的变化趋势基本一致,但变幅偏大。此外,全球增暖停滞现象在武汉市最近十几年也有所体现。 |

| Abstract: | Based on the monthly maximum and minimum temperature data at Wuhan meteorological station in 1906-2015, annual mean temperature during the 110 years was reconstructed and the temporal change was analyzed. The main conclusions are: (1) Annual mean temperature of Wuhan showed multi-decadal variations. Two warm periods were experienced during 1906-1946 and 1994-2015; and between 1947 and 1993, annual mean temperature was relatively low. (2) At multi-decadal temporal scales, annual mean temperature of Wuhan showed several significant warming and cooling trends. The largest warming trends at 30- and 50-year scales were detected during 1980-2009 and 1960-2009, with linear trends amounting to 2.67±0.48 ℃/30a and 2.20±0.50 ℃/50a, respectively. The strongest cooling trends for the same temporal scales were detected for 1928-1957 and 1925-1974, with linear trends being -1.23±0.48 ℃/30a and -1.40±0.35 ℃/50a, respectively. (3) During the 110 years, there existed three abrupt changes in Wuhan annual mean temperature. During the early 1920s and the mid-late 1990s, temperature of Wuhan turned from cold to warm conditions. In the 1940s, the change was to the opposite. (4) Comparing temperature change of Wuhan with global, hemispheric, and China's country scales, the temperatures showed similar temporal evolution, with Wuhan exhibiting greater amplitude of change. The recent pause in global warming was also observed in Wuhan. |
