摘要:

用60 a Hadley氣候中心的月平均海溫資料,用EOF分析重構(gòu)了4月份印度洋海溫的一致變化型異常,并以此驅(qū)動(dòng)IAP9層大氣環(huán)流模式,分別研究了海溫異常初期適應(yīng)階段、異常當(dāng)月和氣候平均夏季3種時(shí)間尺度下大氣高度場響應(yīng)的傳播和分布特征。研究發(fā)現(xiàn),初期適應(yīng)階段,高度場響應(yīng)的垂直傳播約需4 d,且受控于整層無輻散約束;冷暖位相高度響應(yīng)的水平傳播路徑差異較大,表現(xiàn)出明顯的非對(duì)稱性。海溫異常當(dāng)月,冷位相會(huì)激發(fā)出全球緯向Rossby波;而暖位相則激發(fā)出兩半球洋面上2個(gè)大圓波列,且均有顯著正壓性。對(duì)氣候平均夏季的北半球冷相位,高度響應(yīng)表現(xiàn)為太平洋上空的3條異常緯帶;對(duì)暖相位則表現(xiàn)為太平洋和大西洋上空的2個(gè)大圓波列。而南半球的高度場對(duì)冷位相響應(yīng)主要表現(xiàn)為2波結(jié)構(gòu)的繞極駐波,暖相位激發(fā)出環(huán)球的同心異常緯帶。

Abstract:

Based on EOF analysis on monthly mean SST data for 60 a from Hadley Climate Center, the unipole pattern of Indian Ocean SSTA was reconstructed, which drives IAP9L AGCM to investigate the propagation and distribution of the atmospheric height field during three periods including the initial adapting stage, the exact anomalous month and the climatic mean summer. The results show: during the initial adaption, the vertical propagation of height response approximately reguires 4 d and is restricted to non-divergence of the whole layer. The extending paths of height response present obvious horizohtal asymmetry and show distinct difference between the cold and the warm phase. During the exact anomalous month, the global zonal Rossby waves are inspired by cold phase while two wavelets are aroused by warm phase over the Pacific Ocean in two hemispheres; both of the two phases show remarkable barotropy. For climatic summer in north hemisphere, three anomalous height zones are presented over Pacific Ocean for cold phase, while two wavelets are produced over both Pacific Ocean and Atlantic Ocean for warm case. In southern hemisphere, double peak's stationary polar waves are arosed for cold phase, while global circled anomalous zones are presented for warm case.
