阿拉伯海经历了极端的大气强迫，导致任何海洋中最大的季节性变化。1995年期间，在北方阿拉伯海内进行了6次巡航。收集的数据代表了第一个涵盖整个季风周期的一致数据集。从这些巡航中获得的海洋温度和盐度探测结果被用来描述与季风强迫有关的表层水团的变化。本文记录了平流与当地水团修改对阿拉伯海近地表沃茨T-S季节性极值的作用。季节性变化与季节性加热、阿曼上升流区沃茨的平流、中央盆地埃克曼抽水引起的混合层深度变化以及波斯湾高盐度沃茨的混合有关。
The Arabian Sea experiences extremes in atmospheric forcing that lead to the greatest seasonal variability in any ocean. During 1995, 6 cruises were carried out within the northern Arabian Sea. The data collected represent the first consistent dataset covering an entire monsoonal cycle. Ocean soundings of temperature and salinity from these cruises are used to characterize variability of water masses in the surface layers associated with monsoonal forcing. This paper documents the role of advection versus local water mass modification on seasonal extremes in T‐S in near‐surface waters of the Arabian Sea. Seasonal changes are associated with seasonal heating, advection of waters from the Oman upwelling zone, varying of mixed‐layer depth due to Ekman pumping in the central basin and mixing of high‐salinity waters from Persian Gulf.
