摘　　要：利用1961—2020年逐日气温观测数据以及1979—2020年NCEP再分析资料,基于常规气象统计方法分析塔里木河流域夏季气温的时空变化特征及其相关的海温异常。结果表明:(1)1961—2020年塔里木河流域夏季平均气温整体呈上升趋势,升温速率为0.16℃·(10a)^(-1)。(2)塔里木河流域东部、南部大部地区夏季升温速率较快,流域中部、西部升温速率较缓,中部部分地区呈降温趋势。(3)塔里木河流域夏季气温的空间分布主要表现为一致变化型和南北反向变化型。(4)气温一致分布型主要与前期冬季我国黄海、西北太平洋及低纬西大西洋(或前期春季中高纬太平洋)海温异常有关,南北反向型与前期冬季我国南海、印度洋及中低纬大西洋(或前期春季日本以东海域)海温异常有关。This study analyzes the spatial and temporal variations of summer temperature in the Tarim River Basin and its relationship with sea temperature anomalies.The analysis is based on daily temperature observation data from 1961 to 2020 provided by the Xinjiang Meteorological Information Center and NCEP reanalysis data from 1979 to 2020.The results show the following:From 1961 to 2020,the average summer temperature in the Tarim River Basin exhibited an overall upward trend,with a warming rate of 0.16℃ per decade.Geographically,the eastern and southern parts of the basin experienced faster warming,while the central and western parts showed slower rates of warming,with some central areas even experiencing cooling trends.The spatial distribution of summer temperatures in the basin was characterized by both uniform variation patterns and north-south opposing variation patterns.The uniform temperature pattern was primarily linked to sea temperature anomalies in the Yellow Sea,northwest Pacific Ocean,and low-latitude western Atlantic Ocean during the preceding winter(or the prior spring in the mid-to-high latitude Pacific Ocean).In contrast,the north-south opposing pattern was associated with sea temperature anomalies in the South China Sea,Indian Ocean,and mid-latitude Atlantic Ocean in the preceding winter(or in the waters east of Japan during the prior spring).
