The El Niño–Southern Oscillation (ENSO) represents the most prominent interannual signal within the global ocean–atmosphere system and stands as one of the crucial factors influencing the interannual variability of summer precipitation in the Beijing–Tianjin–Hebei (BTH) region. Based on data such as spring SST (Sea Surface Temperature), summer precipitation in the BTH region, and atmospheric circulation from 1961 to 2023, this study analyzes the interdecadal variation in the relationship between spring ENSO and summer precipitation in the BTH region as well as its possible causes. Results show that the key spring ENSO region significantly impacting the interannual summer-precipitation anomalies in the BTH region underwent an interdecadal shift in the late 1990s, migrating from the eastern Pacific in the earlier period to the central Pacific in the later period. Although SST anomalies (SSTAs) in the key spring ENSO region exhibit a strong negative correlation with the summer precipitation anomalies in the BTH region before and after the shift, the underlying mechanisms differ significantly. When SSTAs exist in the key spring ENSO region, the summer SSTAs in the North Pacific, Indian Ocean, and Atlantic Ocean show different characteristics, which in turn cause circulation anomalies in the tropics and mid-high latitudes through the synergistic effect of SSTAs in different regions. When the key spring ENSO region exhibits warm SSTAs, a distinct anticyclonic circulation is observed in the subtropical northwestern Pacific. After the interdecadal shift, this anticyclonic circulation strengthens, but it still fails to transport water vapor to the BTH region. The BTH region is controlled by a cyclonic circulation. In the earlier period, this cyclonic circulation is associated with SSTAs in the North Pacific, and in the later period, it is caused by the zonal wave train over the Eurasian continent, excited by SSTAs in the North Atlantic. The control of anomalous northerly winds over the BTH region reduces precipitation.

ENSO(El Niño-Southern Oscillation)是全球海气系统最显著的年际信号,也是影响京津冀夏季降水的重要因素之一。本文基于1961~2023年春季海表温度与京津冀夏季降水、大气环流等数据,分析了春季ENSO与京津冀夏季降水关系的年代际变化及其可能成因。结果表明,对京津冀夏季降水年际异常产生显著影响的春季ENSO关键区在1990年代末发生年代际变化,由前期东太平洋到后期转为中太平洋,尽管转变前后春季ENSO关键区海表面温度(Sea Surface Temperature,SST)对京津冀夏季降水异常的影响均表现为较强的负相关,然而其成因却存在显著差异。在春季ENSO关键区的海温出现异常时,北太平洋、印度洋和大西洋的夏季海温会表现出不同的特征,进而通过不同区域海温异常的协同作用引起热带和中高纬环流异常。当春季ENSO关键区表现为暖海温异常时,副热带西北太平洋存在明显的反气旋环流,在发生年代际转变后此反气旋环流相对偏强,但仍未把水汽输送到京津冀地区;京津冀上空受气旋性环流控制,前期的气旋性环流与北太平洋海温异常相关,后期则是由北大西洋的海温异常激发出欧亚大陆上空的纬向波列所引起,偏北风异常控制京津冀地区导致降水异常偏少。

ENSO(El Niño-Southern Oscillation)是全球海气系统最显著的年际信号,也是影响京津冀夏季降水的重要因素之一。本文基于1961~2023年春季海表温度与京津冀夏季降水、大气环流等数据,分析了春季ENSO与京津冀夏季降水关系的年代际变化及其可能成因。结果表明,对京津冀夏季降水年际异常产生显著影响的春季ENSO关键区在1990年代末发生年代际变化,由前期东太平洋到后期转为中太平洋,尽管转变前后春季ENSO关键区海表面温度(Sea Surface Temperature,SST)对京津冀夏季降水异常的影响均表现为较强的负相关,然而其成因却存在显著差异。在春季ENSO关键区的海温出现异常时,北太平洋、印度洋和大西洋的夏季海温会表现出不同的特征,进而通过不同区域海温异常的协同作用引起热带和中高纬环流异常。当春季ENSO关键区表现为暖海温异常时,副热带西北太平洋存在明显的反气旋环流,在发生年代际转变后此反气旋环流相对偏强,但仍未把水汽输送到京津冀地区;京津冀上空受气旋性环流控制,前期的气旋性环流与北太平洋海温异常相关,后期则是由北大西洋的海温异常激发出欧亚大陆上空的纬向波列所引起,偏北风异常控制京津冀地区导致降水异常偏少。

The El Niño–Southern Oscillation (ENSO) represents the most prominent interannual signal within the global ocean–atmosphere system and stands as one of the crucial factors influencing the interannual variability of summer precipitation in the Beijing–Tianjin–Hebei (BTH) region. Based on data such as spring SST (Sea Surface Temperature), summer precipitation in the BTH region, and atmospheric circulation from 1961 to 2023, this study analyzes the interdecadal variation in the relationship between spring ENSO and summer precipitation in the BTH region as well as its possible causes. Results show that the key spring ENSO region significantly impacting the interannual summer-precipitation anomalies in the BTH region underwent an interdecadal shift in the late 1990s, migrating from the eastern Pacific in the earlier period to the central Pacific in the later period. Although SST anomalies (SSTAs) in the key spring ENSO region exhibit a strong negative correlation with the summer precipitation anomalies in the BTH region before and after the shift, the underlying mechanisms differ significantly. When SSTAs exist in the key spring ENSO region, the summer SSTAs in the North Pacific, Indian Ocean, and Atlantic Ocean show different characteristics, which in turn cause circulation anomalies in the tropics and mid-high latitudes through the synergistic effect of SSTAs in different regions. When the key spring ENSO region exhibits warm SSTAs, a distinct anticyclonic circulation is observed in the subtropical northwestern Pacific. After the interdecadal shift, this anticyclonic circulation strengthens, but it still fails to transport water vapor to the BTH region. The BTH region is controlled by a cyclonic circulation. In the earlier period, this cyclonic circulation is associated with SSTAs in the North Pacific, and in the later period, it is caused by the zonal wave train over the Eurasian continent, excited by SSTAs in the North Atlantic. The control of anomalous northerly winds over the BTH region reduces precipitation.

中国东部地处东亚季风区,受东亚夏季风推进过程的影响,中国东部夏季降水异常的空间分布存在明显的年际差异(施能等, 1996; 张庆云等, 2003; 黄荣辉等, 2006, 2008; 丁一汇等, 2018)。若较长时间出现降水偏多、偏少或气温偏高、偏低,风力偏强等现象,会导致干旱、洪涝、热浪等灾害并给农业、工业、畜牧业、水利、运输等行业造成巨大的经济损失。因此,理解中国东部夏季降水异常的变化特征及其作用机理,对于提高我国季风区洪涝灾害的预测能力具有重要意义。
ENSO(El Niño–Southern Oscillation)是全球海—气系统中对东亚气候产生最显著影响的年际信号(张人禾等, 2017),Bjerknes(1969)指出厄尔尼诺和南方涛动分别是ENSO在海洋与大气两个方面的体现。ENSO具有季节锁相性,El Niño与La Niña通常发生发展于北半球夏季,在冬季达到成熟状态,于次年春季减弱直至衰亡(Rasmusson and Carpenter, 1982; Picaut et al., 1997)。在El Niño衰亡期夏季,长江中下游及江南地区降水偏多,而黄河流域、华北地区降水偏少(金祖辉和陶诗言, 1999; 许武成等, 2005);结束时间较晚的El Niño事件,华北地区在次年夏季易发生干旱(邹力和倪允琪, 1997);在La Niña结束且当年转为El Niño的年份,华北雨季降水更容易异常偏少(赵树云等, 2017);此外在El Niño次年夏季西太平洋对流活动受到抑制,使得南海、西太平洋生成台风数目偏少,给东亚带来的台风降水相应偏少(包澄澜和向元珍, 2000)。有关ENSO对北方地区降水年际异常的影响,前人已做过相关研究,华北降水的季节演变存在两个主要模态,其中第一模态主要受ENSO演变过程的影响,华北夏季降水与同期El Niño呈显著负相关关系,El Niño可以通过调节高层与低层的环流系统诱发出与华北夏季干旱年一致的环流型(郝立生等, 2011, 2023)。
ENSO产生的气候影响存在年代际变化特征(Chang et al., 2000a, 2000b; Wang, 2002; 王会军和贺圣平, 2012; Kim et al.,2014; 王东等, 2024)。受太平洋年代际涛动调制作用,与1970年代中期之前相比较,在1970年代中期以后当ENSO事件处于发展阶段,对应华北和东北夏季气温由偏冷变为偏暖;当ENSO事件处于衰减阶段,华北夏季由偏涝变为偏旱,且气温由偏冷变为偏暖(陈烈庭和吴仁广, 1998; 朱益民等, 2007; 宗海锋等, 2010)。ENSO与东亚夏季风的关系在不同年代存在差异,在1970年代中期以前,El Niño次年夏季华北地区与长江流域以南降水偏多,梅雨爆发时间偏晚;在1970年代中期以后,ENSO与东亚夏季风的关系减弱(Wu and Wang, 2002; Gao et al., 2006)。在1960年代中期至1980年代中期,受大西洋多年代际涛动负位相的影响,ENSO与初夏东亚夏季风呈现显著的正相关关系;而在1950年代至1960年代中期与1980年代中期至2010年代,大西洋多年代际涛动处于正位相对应ENSO与初夏东亚夏季风的关系减弱(Xu et al., 2021)。近年来的研究指出El Niño存在多样性,除了赤道东太平洋海表面温度(SST,简称海温)持续暖异常这类传统的El Niño事件外,1990年代末期以来更频繁地发生异常中心西移至赤道中太平洋即中部型El Niño事件(Yeh et al., 2009; Lee and McPhaden, 2010),中太平洋El Niño频繁发生的原因包括以下两个方面,其一是外部强迫因素,自1990年代以来的全球变暖使得赤道太平洋温跃层变浅,更有利于中太平洋El Niño事件发生 (Yeh et al., 2009);其二是内部变率,20世纪末大西洋多年代际涛动处于正位相,有利于增加中太平洋的纬向海温梯度,进而增强纬向平流反馈作用,导致更多的中太平洋El Niño事件发生(Gan et al., 2023)。不同类型的El Niño进一步导致中国雨带存在不同的分布特征(Feng et al., 2011; 袁媛等, 2012),使用CAM4(Community Atmosphere Model Version 4)对中太平洋El Niño与东太平洋El Niño的影响进行模拟,可以得到两者影响存在差异,且中太平洋El Niño对应的东亚夏季降水异常更明显(Chen et al., 2014)。
关于ENSO对气候的影响机制,前人研究表明在热带地区,当El Niño发生时,赤道东太平洋海温偏暖,热带太平洋地区的纬向海温梯度减弱,导致其上空的Walker环流(Walker Ciuculation)偏弱,印度—西太平洋出现异常下沉运动,对应局地的Hadley环流减弱。有研究指出,在El Niño发展期,根据Matsuno-Gill效应,赤道东太平洋增暖在其西北侧激发出气旋性环流,气旋性环流西侧的东北风异常与气候态的东北信风相叠加,使得西太平洋海表面温度偏冷,进而在西北太平洋存在反气旋性环流,而反气旋性环流东侧的东北风进一步与东北信风叠加,使得冷海温异常得以维持,即风—蒸发—海温反馈机制,在副热带西北太平洋的反气旋性环流得以较长时间存在(Gill, 1980; Wang et al., 2000; Wang and Zhang, 2002)。在El Niño衰亡期,由于Walker环流减弱,东印度洋出现西传的海洋Rossby波,使得印度洋增暖,进而激发出东传的Kelvin波,使得反气旋在西北太平洋维持,也就是印度洋电容器效应(Yang et al., 2007; Xie et al., 2009; Wu et al., 2010)。在热带外地区,ENSO事件所伴随的热带太平洋对流活动和非绝热加热会在绝对涡度较大的副热带地区产生Rossby波源,在背景气流的作用下,异常波源产生的扰动向下游传播从而形成大尺度遥相关波列(Hoskins and Karoly, 1981; Sardeshmukh and Hoskins, 1988)。在El Niño发生时,赤道中太平洋降水偏多,释放凝结潜热,在赤道太平洋地区形成热源,进而激发出“太平洋—北美”型波列(Wallace and Gutzler, 1981; Barnston and Livezey, 1987)。
京津冀地区是我国政治和文化中心,也是我国北方重要的经济发展区。夏季暴雨洪涝和少雨干旱是主要的气象灾害,对社会经济和人民生命财产安全有重大影响。关于ENSO对华北地区和京津冀夏季降水的影响,前人开展了大量研究,但有关ENSO与京津冀地区夏季降水关系的年代际变化却少有涉及。因此,本文聚焦近60年影响京津冀地区夏季降水的春季ENSO区域的年代际变化,分析不同年代背景下,不同区域的ENSO是如何产生影响东亚地区的环流异常,这对于提高京津冀地区汛期气候预测技巧具有重要意义。
本文使用的资料包括:(1)京津冀地区89个气象站1961~2023年逐月降水数据,京津冀地区夏季降水量选用6~8月降水量,区域平均值是所有站点的平均值;(2)CRU (Climatic Research Unit)提供的0.5°×0.5°的全球月平均降水数据(Harris et al., 2020);(3)Hadley Center提供的1°×1°的HadISST1 (Hadley Centre Sea Ice and Sea Surface Temperature dataset version 1)全球月平均海表面温度数据(Rayner et al., 2003);(4)逐月的Niño指数(Niño区海温距平),来自国家气候中心提供的130项气候指数;(5)ECMWF (European Centre for Medium-Range Weather Forecasts)提供的0.25°×0.25°的ERA5 (fifth generation ECMWF atmospheric reanalysis of the global climate)全球月平均再分析数据,使用到的变量包括纬向风、经向风、位势高度、水汽与整层水汽通量散度(Hersbach et al., 2020)。本文所选择的研究时段为1961~2023年。
对资料使用Butterworth数字滤波器进行带通滤波提取出3~9年的年际振荡信号,再使用滑动相关、回归分析等方法并进行显著性检验。在诊断静止Rossby能量传播时使用到波作用通量,在纬向变化的气候平均流中具有较好的表现效果:
$ W = \frac{1}{2|\bar{U}|}\left[ \begin{array}{l} \bar{U}(\psi_x'^2 - \psi') + \bar{V}(\psi_x'\psi_y - \psi'\psi_{xy}') \\ \bar{U}(\psi_x'\psi_y - \psi'\psi_{xy}') + \bar{V}(\psi_y'^2 - \psi'\psi_{yy}') \end{array}\right], $
其中,$ \bar{U} = (\bar{U}, \bar{V})^{\text{T}}$表示稳定的纬向变化基本流,Ψ’表示扰动流函数。
对春季不同Niño指数与京津冀夏季降水求21年滑动相关系数,由图1可见,在不同年代春季Niño指数与夏季京津冀降水的关系并非保持稳定不变,而是存在明显差异,且不同区域的Niño指数与降水求相关得到的结果并不相同。在1970年代末至1990年代末春季Niño1+2指数[Niño1+2区(90°W~80°W,10°S~0°)区域平均海温距平]与夏季京津冀降水成明显负相关且通过90%信度水平的显著性检验,在后期两者之间的相关性减弱;春季Niño4指数[Niño4区(160°E~150°W,5°S~5°N)区域平均海温距平]在前期与夏季京津冀降水成正相关,直至近期两者关系转变成明显负相关且通过90%信度水平的显著性检验;在整个分析时段中,春季Niño3指数[Niño3区(150°W~90°W,5°S~5°N)区域平均海温距平]、Niño3.4指数[Niño3.4区(170°W~120°W,5°S~5°N)区域平均海温距平]与夏季京津冀降水的关系并不明显,大部分时段未通过90%信度水平的显著性检验;可以发现显著影响夏季京津冀降水的区域由前期的Niño1+2区转变为后期的Niño4区。因此我们选取两个区域负相关最显著的时间段:1976~1996年(Niño1+2区)与2001~2021年(Niño4区),来分析不同年代春季ENSO对夏季京津冀降水的影响差异,以上选取的两个时间段内的Niño1+2指数与Niño4指数具有相对独立性。前期冬季4个Niño指数与京津冀夏季降水的21年滑动相关系数及基本表现与春季Niño指数得到的结果相似,但不同区域海温与降水之间的关系差异不如春季明显(图略)。
为了进一步验证上述结论,将CRU夏季降水场分别对以上两个时间段的春季Niño指数作回归,可以得到不同年代下夏季京津冀降水异常的空间分布(图2)。在1976~1996年,春季Niño1+2指数与夏季京津冀降水呈现负相关,表明当春季Niño1+2区海温偏暖时,夏季京津冀地区降水异常偏少,环渤海区域偏少最明显且通过90%信度水平的显著性检验;在2001~2021年,春季Niño4指数与夏季京津冀大部分区域降水成明显负相关,表明当春季Niño4区海温表现为暖异常,对应京津冀地区夏季偏旱,除河北西南部分地区以外,其他区域大都通过90%信度水平的显著性检验。这与使用气象站数据得到的回归结果具有较高的一致性。
通过滑动相关与回归分析,我们得到春季Niño指数与夏季京津冀降水的关系存在年代际差异,接下来将聚焦1976~1996年与2001~2021年这两个时间段对春季ENSO影响夏季京津冀降水异常展开成因分析。
虽然两个时段不同Niño指数都与京津冀夏季降水呈负相关,但降水异常的成因是否存在差异,下面将从不同区域的Niño指数相关的海温异常和引起的大气环流异常来进一步分析。
首先把夏季海温场分别对1976~1996年与2001~2021年不同区域的春季Niño指数作回归,可以得到不同时段夏季全球海温异常的空间分布(图3)。在1976~1996年,春季赤道东太平洋的暖海温异常能维持到夏季,在热带印度洋西部存在一定范围的暖海温异常,而在热带西太平洋与中纬度北太平洋表现为海温偏冷。在2001~2021年,春季赤道中太平洋海温偏暖同样可以维持到夏季,与1976~1996年时段不同的是,热带东印度洋、北太平洋东部沿岸存在较大范围且显著的暖海温异常,热带西太平洋冷海温异常减弱,中纬度北大西洋由较弱的海温异常转为明显的北冷南暖分布。下面从太平洋、印度洋和大西洋海温异常的协同作用影响欧亚地区热带和中高纬环流异常进行分析。
根据两个时段的不同ENSO关键区的海温异常,进一步分析产生的异常大气环流对京津冀地区夏季降水异常的影响。通过把夏季850 hPa水平风场分别对两个时段春季Niño指数作回归(图4),可以得到当两个时间段春季Niño指数为正时,夏季东亚沿岸均存在明显的PJ(Pacific–Japan)波列,副热带西北太平洋受反气旋环流控制,日本海附近存在气旋性环流,京津冀地区位于气旋西侧偏北风控制下,对应降水异常偏少(图2)。具体来看,在1976~1996年,Niño1+2区为暖异常时,副热带西北太平洋反气旋西侧的西南气流与日本海气旋西侧的偏北风在长江附近辐合,京津冀地区受偏北风控制,降水异常偏少(图4a),而在2001~2021年,当Niño4指数为正时,副热带西北太平洋存在更明显的反气旋环流,日本海上空受更强的气旋性环流控制,位于中纬度的气旋其西侧偏北风延伸控制到我国东南沿海地区,京津冀地区存在更强的偏北风异常(图4b),对应此时间段的降水负异常更明显(图2b)。
由环流所引起的水汽输送是造成降水的最直接因素,图5是不同年代下夏季整层积分水汽通量散度与不同时段春季Niño指数作回归得到的结果。可以看到在两个研究时段,当Niño指数为正时,京津冀地区均表现为水汽通量散度正异常,对应此处存在辐散,与降水偏少相匹配(图2)。在1976~1996年,当Niño1+2指数为正值时,水汽通量散度正异常比较明显的区域主要位于环渤海以及冀中地区,且以上区域大都通过显著性检验(图5a),与降水偏少的区域具有较高的一致性(图2a)。与前一研究时段相比,在Niño4区表现为暖异常时,2001~2021年在京津冀地区东北部存在明显的正异常辐散中心(图5b),对应此时段京津冀地区的东北部降水偏少更加明显(图2b)。
图6为夏季200 hPa速度势及对应辐散风对不同区域的春季Niño指数的回归图,图7是夏季10°S~10°N平均的纬向垂直环流回归不同时段的春季Niño指数得到的结果。在1976~1996年,热带中东太平洋海温偏暖,热带太平洋西部海温偏冷(图3a),热带太平洋地区纬向温度梯度减弱,对应在热带太平洋地区存在两个速度势异常中心,分别是位于海洋性大陆上空的速度势正异常中心与位于热带中东太平洋的速度势负异常中心,速度势负异常也就是辐散中心对应的上升运动位于热带太平洋中东部,速度势正异常即辐合中心对应的下沉运动位于海洋性大陆附近(图6a),导致热带太平洋地区的Walker环流受到抑制(图7a)。一方面热带中东太平洋的上升运动会释放凝结潜热,根据Matsuno-Gill效应,在热带中太平洋的西北侧激发出气旋性环流(Gill, 1980),其西侧存在的东北风与气候态的东北信风相叠加,使得热带西太平洋海温偏冷(图3a),有利于在此处生成反气旋性环流(图4a),而反气旋性环流东侧的东北风与东北信风进一步叠加,异常冷海温得以维持,在副热带西北太平洋的反气旋性环流得以较长时间存在;另一方面在热带西太平洋高层为速度势的辐合中心,对应其低层为速度势的辐散中心,进而在热带西太平洋激发出偏东风异常(图4a);在两者的共同作用下副热带西北太平洋出现反气旋性环流(图4a),此反气旋西侧的西南气流仅延伸至长江流域,并不能给京津冀地区提供充足的水汽输送(图5a)。在2001~2021年,热带太平洋暖海温异常西移至中太平洋,且海温增暖更为明显(图3b),对应热带太平洋高层存在两个强度更强的速度势异常中心,速度势负异常中心西移至热带中太平洋,速度势正异常中心位于热带西太平洋与海洋性大陆上空(图6b),与此同时印度洋的海温暖异常更明显(图3b),因此在印度洋上空出现一个较明显的速度势负异常中心(图6b)。与前一时段相比,用Niño4指数回归得到的太平洋地区高层异常速度势强度更强,范围更广,对应Walker环流受到更明显的抑制作用(图7b),进而在热带西太平洋存在更强的下沉运动,低层的偏东风异常更为显著,另一方面印度洋增暖更明显对应更强的对流上升运动,有利于在西北太平洋地区出现更明显的反气旋式切变,边界层的Ekman辐散更强,两者的共同作用更明显地削弱了热带西太平洋的对流活动,在副热带西北太平洋激发出的反气旋环流强度更强(图4b),反气旋主要控制西北太平洋海上区域,并未对华北地区的水汽条件产生显著影响(图5b)。
图8给出夏季北半球中高纬200 hPa位势高度异常及相应的波活动通量与两个时段春季Niño指数的回归图,图9为夏季北半球中高纬200 hPa纬向风异常分别回归到不同区域的春季Niño指数得到的结果,主要关注北半球中高纬环流异常与大尺度波列的联系。可以看出,两个时段夏季北半球中高纬大尺度准定常波列存在显著差异。在1976~1996年,当Niño1+2区表现为暖异常时,欧亚上空的纬向波列只影响到中亚地区,京津冀地区更多受由北太平洋延伸而来的低压影响。与热带地区海表面温度异常导致的直接热力强迫响应不同,经向海温梯度引起的斜压不稳定在中高纬地区占主导地位(Fang and Yang, 2016; Tao et al., 2020)。在此阶段,中纬度北太平洋西部为一致的冷海温异常(图3a),其南侧的经向海温梯度增加,相应地低层大气斜压性增强,有利于出现更多的瞬变涡旋活动。大气瞬变涡旋活动可以重新分配对流层中高层的热量和动量,有效地影响大尺度大气环流。根据瞬变涡旋平均流相互作用,瞬变涡旋活动增强往往会引起异常瞬变涡旋通量的辐合,进而导致高层纬向西风异常增加(Lau and Holopainen, 1984; Fang and Yang, 2016; Tao et al., 2020)。在日本南侧存在纬向风正异常中心(图9a),这与200 hPa中纬度北太平洋延伸至我国北方的负位势高度异常相对应(图8a),京津冀地区受异常东北风控制(图4a),缺乏充足的水汽条件(图5a),因此不易产生降水(图2a)。而在2001~2021年,用Niño4指数进行回归得到的结果与前期存在很大差异,当Niño4指数为正值时,中纬度北大西洋为冷海温异常(图3b),对应大西洋多年代际涛动的负位相,有利于在中高纬激发出一支横跨欧亚的Rossby波列(姜大膀等, 2024),该波列起源于大西洋,经过乌拉尔山脉附近的低压异常与贝加尔湖附近的高压异常最终传至我国北方地区,与从低纬印度洋传来的经向波列相叠加,导致贝加尔湖附近存在高压异常,东北亚地区受低压控制,且此时波活动通量强度更强,对应影响我国北方地区的低压更为明显(图8b),异常偏北风控制京津冀地区(图4b),水汽通量散度为明显的正异常(图5b);与此同时淮河流域上空的纬向风正异常位于气候态南侧(图9b),对应较弱的东亚夏季风,最终导致京津冀地区降水异常偏少(图2b)。
ENSO是全球海气系统最显著的年际信号,也是影响京津冀夏季降水年际变化的重要因素之一。本文使用1961~2023年京津冀逐月降水数据、ERA5逐月大气再分析数据与HadISST1逐月海温数据,采用年际滤波与回归分析等方法,对影响京津冀夏季降水的春季ENSO区域随年代发生空间迁移这一现象进行分析,并探究相关的物理机制,得到的结论如下:
(1)春季ENSO对京津冀夏季降水年际异常的影响在1990年代末发生年代际转变,由前期春季东太平洋海温偏暖对应京津冀夏季负的降水异常转为后期春季中太平洋海温与京津冀夏季降水成负相关,并选取两个负相关最强的时间段进行分析,其中Niño1+2指数与京津冀降水的负相关关系在1976~1996年时段最强,Niño4指数与京津冀降水的负相关关系在2001~2021年时段最强。
(2)从热带途径来看,自1970年代中期至1990年代中期,春季东太平洋的海温偏暖可以维持到夏季,在热带西太平洋表现为海温偏冷,热带太平洋地区的纬向海温梯度减弱,异常Walker环流抑制热带西太平洋的对流活动,在副热带西北太平洋生成异常反气旋性环流,此反气旋性环流仅向北延伸至长江流域,并不能为京津冀地区提供充足的水汽输送;与前一段时间相比,从2000年代初至今,春季中太平洋的海温异常偏暖信号能够持续到夏季,同样产生异常Walker环流显著抑制热带西太平洋的对流活动,存在差异的是印度洋北部与海洋性大陆增温明显,通过印度洋电容器效应产生东传的Kelvin波,有利于在副热带西北太平洋生成异常反气旋性环流,此反气旋性环流主要控制副热带西北太平洋,同样不能把水汽输送到京津冀地区。
(3)从热带外途径来看,自1970年代中期至1990年代中期,春季东太平洋出现El Niño时,在夏季中纬度北太平洋西部海温偏冷,其南侧的经向海温梯度增加,低层大气斜压性增强,有利于产生更多的瞬变涡旋活动,使得北太平洋至我国东北地区出现大范围的位势高度负异常,京津冀地区受偏北风异常的影响,水汽条件不足,京津冀地区夏季降水异常偏少;与前一段时间相比,从2000年代初至今,春季中太平洋出现El Niño时,中纬度大西洋夏季海温呈现冷异常,在中高纬度欧亚大陆上空激发出纬向传播的Rossby波列,与从印度洋传来经向波列的影响相叠加,使得东北亚地区存在位势高度负异常中心,京津冀地区受异常偏北风的影响,使得京津冀夏季降水异常偏少。
与京津冀地区夏季降水成明显负相关的春季海温区域由热带东太平洋移至热带中太平洋,转变发生在2000年前后,这可能是与近期中太平洋El Niño频发相关(Lee and McPhaden, 2010),此文中主要分析春季El Niño对京津冀夏季降水影响的年代际差异,而La Niña与El Niño本身振幅具有非对称性,且中纬度大气的动力过程是非线性的(Wang and Yang, 2023),另外近些年发生更多的是东太平洋La Niña事件,因此关于La Nina对京津冀地区夏季降水影响中涉及的非线性过程有待未来做进一步的研究。
