【摘要】：为了探讨近50年来辽宁省气候变化特征及其与厄尔尼诺的关系,文章根据1965—2013年辽宁省23个气象站点的降水、年均气温数据与表征厄尔尼诺南方涛动(ENSO)事件的热带太平洋海表温度距平和南方涛动指数资料,利用气候倾向率、M-K突变检验以及反距离权重插值等方法进行分析研究,结果表明:1965—2013年辽宁省降水量由东南向西北逐渐减少,在多个时间段内发生突变现象;气温有显著的上升趋势,并在空间上呈现由东北向西南逐渐增加的趋势;降水变化与ENSO事件强度存在着一定的负相关性,而气温变化与ENSO事件强度没有显著的相关性。
[Abstract]:In order to explore the characteristics of climate change and its relationship with El Nino in Liaoning Province in recent 50 years, based on the precipitation of 23 meteorological stations in Liaoning Province from 1965 to 2013, the annual temperature data and the tropical Pacific sea surface temperature anomaly and Southern Oscillation index data, which characterize the (ENSO) event of El Ni 帽 o Southern Oscillation, are analyzed and studied by means of climate tendency rate, M 鈮，
