Observations and Dynamics of the Indonesian Throughflow

Sprint Tall/Hautala Funds被提供用于对印度尼西亚贯流的观测进行广泛的分析，并结合一个简单的减轻重力的数值模式来阐明在季节到年度时间尺度上的动力学作用。观测数据集包括浅层压力计网络、正在进行的ADCP和CTD海面测量、海流计系泊、水文和XBT剖面、风数据和海面高度测量。将讨论的主要科学问题是：(1)贯穿流量的平均值和变化性；(2)在年、半年和季节内的时间尺度上造成变化性的过程；(3)这种变异性对热量和盐分输送的影响；(4)南爪哇洋流如何改变盆地中的水团结构；(5)与1997-1998年厄尔尼诺事件有关的变化。

Sprintall/HautalaFunds are provided to conduct an extensive analysis of observations of the Indonesian throughflow in conjunction with a simple, reduced gravity numerical model to elucidate the dynamics acting on seasonal to annual time scales. The observational data set consist a network of shallow pressure gauges, underway ADCP and CTD surface measurements, a current meter mooring, hydrographic and XBT sections, wind data and sea surface altimetry. The main scientific question that will be addressed are: (1) what are the mean and variability of the throughflow; (2) what are the processes that cause variability on annual, semi-annual, and intraseasonal time scales; (3) what is the impact of this variability on heat and salt transports; (4) how does the South Java Current alter the water mass structure in the basin, and (5) what are the changes associated with the 1997-1998 El Nino event.
