利用卫星高度计资料,研究了季节内Kelvin波在印度尼西亚贯穿流海域的传播。起源于赤道印度洋的Kelvin波抵达印度洋东边界后,以沿岸Kelvin波的形式沿苏门答腊-爪哇岛西南沿岸向东传播,15天后抵达龙目海峡,并分为三支:一支向北传播,5天后抵达望加锡海峡,相速度约为1.69 m s~(-1);一支向东传播,5天后抵达翁拜海峡,相速度约为1.91–2.86 m s~(-1);一支沿松巴岛西南沿岸传播,相速度约为1.96 m s~(-1)。季节内Kelvin波在该海域的传播速度与第一和第二斜压模Kelvin波一致。 Based on satellite altimetry data, the propagation of Kelvin waves in the through-flow waters of Indonesia during the seasons was studied. Kelvin waves, originating in the equatorial Indian Ocean, reach the eastern boundary of the Indian Ocean and propagate along the coast of Kelvin waves eastward along the southwestern coast of Sumatra-Java Island. It arrives in the Lombok Strait 15 days later and is divided into three branches: one propagating northwards and 5 After arriving in the Makassar Strait, the phase velocities were about 1.69 ms -1 (-1.69 ms -1). One arrived eastward and reached the Umbai Strait in 5 days. The phase velocity was about 1.91-2.86 ms -1. Spread on the southwest coast of Pakistan, the phase velocity is about 1.96 ms ~ (-1). The seasonally Kelvin waves propagate in this area at the same rate as the first and second baroclinic Kelvin waves.
