【摘要】：印度尼西亚贯穿流穿过印度尼西亚海复杂连通的海峡从太平洋流入印度洋,是太平洋和印度洋之间进行水体及热量交换的重要通道,也是全球气候系统和热盐环流的重要组成部分。观测表明,印度尼西亚贯穿流海域海表高度、海表温度和海流存在显著的季节内变化,其周期介于20-90天之间。由于地处太平洋—印度洋水交换要塞,印尼海域海洋季节内变化对印度尼西亚贯穿流输送有着显著影响。本文利用1993-2012年间AVISO卫星高度计的海表面高度资料和NCEP再分析风场资料,首先通过滤波处理、相关分析等方法对季节内时间尺度海表高度异常信号在印度尼西亚贯穿流及其周边海域的分布特征进行初步分析,然后又通过相关分析和合成分析进一步系统剖析了季节内信号在研究海域内的传播过程。结果表明,赤道印度洋纬向风异常所激发的季节内赤道Kelvin波向东传播,在印度洋东边界反射成为沿岸Kelvin波,沿苏门答腊-爪哇岛岛链西南沿岸继续向东传播并穿过途经海峡依次进入印尼海,最远可以抵达望加锡海峡和翁拜海峡。其传播路径主要有:(1)沿小巽他群岛向东传播,最远可以到达翁拜海峡;(2)在苏门答腊岛南端进入巽他海峡并沿着苏门答腊岛东岸传播,但是却不能传播到卡里马塔海峡;(3)在爪哇岛经龙目海峡进入印尼海继而向北抵达望加锡海峡;(4)穿过龙目海峡之后沿着岛岸向爪哇海方向传播。
[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.
