The governing processes and the variability of the upwelling close to the South Vietnamese coastal area will be investigated by means of ship experiments and modell studies. Altogether four cruises will be conducted in different seasons and years, observing the upwelling phenomenon in summer, the downwelling in winter and the situation in the transition phase. Measurements will be taken on a fixed station grid with an average station distance of 20 nm and one mooring station located in the expexted cente of the upwelling. The modelling study comprises the application of two models on different spatial scales. The large scale model will include the entire South China Sea, whereas the small scale model will only cover the upwelling area and its vicinity. Firstly, both models will be forced by NCAR/NCEP data in order to validate the model but also to get an indication of the variability over the last 50 years. Secondly, the two years 2002 and 2003, i.e., the years of the four cruises will be simulated in order to have the direct link between modelling and observations, using the best available set of actual forcing data for this period.

将通过船模试验和莫代尔研究来研究南越沿岸附近上升流的控制过程和变异性。总共将在不同的季节和年份进行四次巡航，观察夏季的上升流现象，冬季的下沉现象和过渡阶段的情况。测量将在一个固定的站网上进行，平均站距为20海里，一个系泊站位于上升流的扩张中心。模型研究包括两个模型在不同空间尺度上的应用。大比例尺模式将包括整个南中国海，而小比例尺模式将只覆盖上升流区及其附近。首先，这两个模型都将受到NCAR/NCEP数据的强制，以便验证模型，同时也得到过去50年来变化的指示。其次，将模拟2002年和2003年这两年，即四个航次的年份，以便在模拟和观测之间有直接联系，使用这一时期现有的最佳实际强迫数据集。
