Modelling Primary Production in the Arabian Sea

印度洋风强迫环流的数值模式将与光合作用-辐照度模式相结合，以研究西南季风期间在阿拉伯海西北部观测到的强烈上升流和相关的初级生产。模型的扩展正在进行中，以包括显式的混合层过程。新建立的光合-辐照模型将与物理模型耦合，以便更深入地研究上升流过程及其对该地区海表温度（SST）、生物初级生产和海洋碳收支的影响。耦合模型将提供一种机制，将卫星高度计、海表温度和海洋颜色数据整合到一个共同的一致框架中进行分析和解释。该模型将用于即将到来的JGOFS阿拉伯海过程研究的设计，通过量化预期的可变性，使用模型数据来测试抽样方案，并通过提供对当前条件的“快速”估计。该模型还可用于分析观测结果，允许在更广泛的空间和时间框架内解释点测量结果。

A numerical model of the wind-forced circulation of the Indian Ocean will be coupled with a photosynthesis-irradiance model to investigate the intense upwelling and associated primary production that is observed in the northwestern Arabian Sea during the southwest monsoon. Extensions of the model are underway to include explicit mixed-layer processes. The newly constructed photosynthesis-irradiance model will be coupled to the physical model to allow a more indepth investigation of the upwelling process and its effect on sea surface temperature (SST), biological primary production, and the oceanic carbon budget in this region. The coupled model will provide a mechanism for integrating satellite altimeter, SST and ocean color data into a common coherent framework for analysis and interpretation. The model will be used in the design of the forthcoming JGOFS Arabian Sea Process Study by quantifying the expected variability, using model data to test sampling schemes, and by providing "quick-look" estimates of present conditions. The model will also be useful in the analysis of observations, allowing interpretation of point measurements in a broader framework in both space and time.
