【摘要】:印度尼西亞貫穿流穿過印度尼西亞海復(fù)雜連通的海峽從太平洋流入印度洋,是太平洋和印度洋之間進(jìn)行水體及熱量交換的重要通道,也是全球氣候系統(tǒng)和熱鹽環(huán)流的重要組成部分。觀測(cè)表明,印度尼西亞貫穿流海域海表高度、海表溫度和海流存在顯著的季節(jié)內(nèi)變化,其周期介于20-90天之間。由于地處太平洋—印度洋水交換要塞,印尼海域海洋季節(jié)內(nèi)變化對(duì)印度尼西亞貫穿流輸送有著顯著影響。本文利用1993-2012年間AVISO衛(wèi)星高度計(jì)的海表面高度資料和NCEP再分析風(fēng)場(chǎng)資料,首先通過濾波處理、相關(guān)分析等方法對(duì)季節(jié)內(nèi)時(shí)間尺度海表高度異常信號(hào)在印度尼西亞貫穿流及其周邊海域的分布特征進(jìn)行初步分析,然后又通過相關(guān)分析和合成分析進(jìn)一步系統(tǒng)剖析了季節(jié)內(nèi)信號(hào)在研究海域內(nèi)的傳播過程。結(jié)果表明,赤道印度洋緯向風(fēng)異常所激發(fā)的季節(jié)內(nèi)赤道Kelvin波向東傳播,在印度洋東邊界反射成為沿岸Kelvin波,沿蘇門答臘-爪哇島島鏈西南沿岸繼續(xù)向東傳播并穿過途經(jīng)海峽依次進(jìn)入印尼海,最遠(yuǎn)可以抵達(dá)望加錫海峽和翁拜海峽。其傳播路徑主要有:(1)沿小巽他群島向東傳播,最遠(yuǎn)可以到達(dá)翁拜海峽;(2)在蘇門答臘島南端進(jìn)入巽他海峽并沿著蘇門答臘島東岸傳播,但是卻不能傳播到卡里馬塔海峽;(3)在爪哇島經(jīng)龍目海峽進(jìn)入印尼海繼而向北抵達(dá)望加錫海峽;(4)穿過龍目海峽之后沿著島岸向爪哇海方向傳播。
[Abstract]:Indonesia runs through the intricately connected straits of the Indonesian Sea into the Indian Ocean from the Pacific Ocean, which is an important conduit for the exchange of water and heat between the Pacific and the Indian Ocean, It is also an important part of the global climate system and thermohaline circulation. The observations show that the sea surface height, sea surface temperature and current in Indonesia vary significantly in season, and their periods range from 20 to 90 days. Because of its location in the Pacific Ocean and Indian Ocean water exchange fortress, the seasonal variation of the ocean in the Indonesian sea area has a significant influence on the Indonesian through-flow transport. In this paper, the sea surface height data of AVISO satellite altimeter from 1993 to 2012 and the wind field data from NCEP reanalysis are used. Correlation analysis and other methods are used to analyze the distribution characteristics of time-scale sea surface height anomaly signals in Indonesia and its surrounding waters. Then, the propagation process of the signal in the studied sea area is analyzed systematically by correlation analysis and composite analysis. The results show that the equatorial Kelvin wave propagates eastward in the season caused by the zonal wind anomaly in the equatorial Indian Ocean, and reflects to the coastal Kelvin wave at the eastern boundary of the Indian Ocean. Along the southwestern coast of the Sumatra-Java island chain, it continues to spread eastward and passes through the Strait into the Indonesian Sea, reaching as far as the Strait of Wangkassi and the Strait of Ompai. The main transmission routes are as follows: (1) spread eastward along the Sunda Islands as far as the Strait of Oombe; (II) entering the Sunda Strait at the southern tip of Sumatra and spreading along the eastern coast of Sumatra, but not to the Karimata Strait; (III) entering the Sea of Indonesia through the Strait of Longmen in Java and reaching the Strait of Wangassi in the north; (4) propagate along the shore of the island toward the Java Sea after crossing the Longmen Strait.
