在1979年东北季风向西南季风过渡期间和之后，在索马里盆地进行了中等深度的水文观测。讨论了与同一时间段内绝对电流的测量有关的数据。Warren等人早期的水团识别。(1966)通过引入定义明确的赤道水团而得到确认和推广。在3个不同的空间尺度上分析了水团的分布及其随季风风场变化的时间演变。赤道和近岸潜流是中间层水团大规模重新分布的重要因素。跨赤道的水交换，特别是高盐度红海水，主要局限于东非海岸附近的一个狭窄区域。没有观测到这些洋流对西南季风爆发的明显响应。在中尺度范围内，含有赤道的反气旋次表层涡旋…
Abstract Hydrographic observations at intermediate depth in the Somali Basin have been made during and after the transition from the northeast monsoon to the southwest monsoon, 1979. The data are discussed in relation to measurements of absolute currents during the same time period. Earlier water-mass identification by Warren et al. (1966) is confirmed and extended by introducing a well-defined Equatorial Water Mass. The distribution of water masses and its temporal evolution with the changing monsoonal wind field is analyzed on three different spatial scales. Equatorial and near-coastal undercurrents are an important factor in the large-scale redistribution of water masses in the intermediate layers. Cross-equatorial exchange of water, in particular highly saline Red Sea water, is largely confined to a narrow region off the East African Coast. No obvious response of these currents to the onset of the southwest monsoon is detected. In the mesoscale range anticyclonic subsurface eddies containing Equatoria...
