摘要:
基于1963—2018年日平均气温和年降水量数据,利用线性趋势分析法、累积距平检验法、信噪比检验方法和Mann-Kendall趋势分析等方法,分析了贵州修文气温和降水的变化特征。结果表明:近55年来修文年平均气温为13.8℃,年均气温总体呈显著上升趋势,增速为0.11℃/10 a; 在2000年年平均气温发生由低温到高温的突变,且气候变暖在最低温上表现更为突出; 修文年平均降水量为1 144.8 mm,年降水量在波动中总体上呈显著下降趋势,年降水量下降幅度为31.8 mm/10 a; 从季节变化来看,自20世纪80年代春、夏、秋季降水总体呈明显波动下降趋势,冬季降水下降趋势不明显; 降水量年内分配十分不均,主要集中在5—9月,且夏季降水量基本均占全年降水量的50%左右。年降水量在1980年降水量存在由多到少的突变。
Abstract:
Trend analysis, cumulation anomaly analysis, signal-to-ration test and Mann-Kendall test were used to analyze air temperature and precipitation annual variability in Xiuwen of Guizhou from 1963 to 2018. It is found that in recent 55 years, the annual mean temperature was 13.8℃, it rose significantly, increased by 0.11℃/decade, and an abrupt change from low to high occurred in 2000, climate change was more pronounced at the lowest temperatures; the annual precipitation was 1 144.8 mm, it showed the significantly decreasing trend in 55 years, decreased by 31.8 mm/decade; the precipitation trend of spring, summer and autumn significantly reduced after 1980, and it did not significantly reduced in winter; annual distribution of precipitation in Xiuwen area was very uneventful, the precipitation mainly occurred from May to September, and the precipitation in summer basically accounted for 50% of the annual precipitation; the abrupt change of precipitation occurred in 1980.
