沿着爪哇-苏门答腊印度洋海岸的上升流是对与季风气候相关的区域风的响应。在东南季风期间（6 - 10月），上升流中心向西迁移，并向赤道方向移动，同时具有较低的海表温度。迁移路径取决于沿岸风的季节性演变和科里奥利参数的纬度变化。上升流最终终止，由于与西北季风的爆发和印度洋赤道开尔文波的冲击风的逆转。爪哇-苏门答腊上升流的显着年际变化通过印度尼西亚通流（ITF）和异常东风与ENSO有关。在厄尔尼诺事件期间，爪哇-苏门答腊的上升流在时间（到11月）和空间（更接近赤道）上都有延伸。在厄尔尼诺（拉尼娜）期间，ITF携带较冷（较暖）的水，使温跃层深度变浅（加深），并增强（减少）上升流强度。
Upwelling along the Java‐Sumatra Indian Ocean coasts is a response to regional winds associated with the monsoon climate. The upwelling center with low sea surface temperature migrates westward and toward the equator during the southeast monsoon (June to October). The migration path depends on the seasonal evolution of alongshore winds and latitudinal changes in the Coriolis parameter. Upwelling is eventually terminated due to the reversal of winds associated with the onset of the northwest monsoon and impingement of Indian Ocean equatorial Kelvin waves. Significant interannual variability of the Java‐Sumatra upwelling is linked to ENSO through the Indonesian throughflow (ITF) and by anomalous easterly wind. During El Niño episodes, the Java‐Sumatra upwelling extends in both time (into November) and space (closer to the equator). During El Nino (La Niña), the ITF carries colder (warmer) water shallowing (deepening) thermocline depth and enhancing (reducing) upwelling strength.
