Observations and Dynamics of the Indonesian Throughflow

提供了Sprintall/ hautala基金，结合一个简单、简化的重力数值模式，对印度尼西亚的通流观测进行广泛分析，以阐明在季节至年时间尺度上的动态。观测数据集包括浅层压力表网络、正在进行的ADCP和CTD地面测量、一个海流计系泊、水文和XBT剖面、风数据和海面高度。要解决的主要科学问题是：(1)通流的平均值和变异性是什么；(2)在年、半年和季节内时间尺度上引起变异的过程是什么；(3)这种变率对热盐输送的影响；(4)南爪哇流如何改变盆地的水团结构；(5)1997-1998年厄尔尼诺事件的相关变化。

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.
