Solar Heating of the Arctic Mixed Layer and Its Impact on Ocean/Ice Interaction

这一建议是由美国国家科学基金会北极系统科学项目推动的北极环境及其在全球变化中的作用系统研究的一部分。这是一个为期三年的项目，利用现有的数据集和模型来评估冰-水界面的热量和盐传递，并获得铅和薄冰在这些过程中的作用的基本见解。冰和铅系统中的短波能量分布模式，结合上层海洋湍流传输模式，将用于现有数据的分析，并量化从北冰洋到北极盆地内海冰的热能通量的时空变化。其他模拟将探讨夏季冰况与混合层温度之间的关系，从海洋到海冰的热量通量季节性变化的长期影响，以及可能导致北极冰盖消失的可能情况。

This proposal is part of a systematic study of the Arctic environment and its role in global change which is promoted by NSF's Arctic System Science Program. It is a three year project utilize existing data sets and models in the evaluation heat and salt transfer at the ice-water interface and to gain fundamental insights into the roles of leads and thin ice in these processes. A model for the distribution of shortwave energy in ice and lead systems, combined with models of turbulent transfer in the upper ocean, will be utilized in the analyses of existing data and to quantify spatial and temporal variations in the flux of heat energy from the Arctic Ocean to the sea ice within the Arctic Basin. Other simulations will explore the relationship between summer ice conditions and mixed layer temperature, long-term implications of seasonal variations in the flux of heat from the ocean to sea ice, and possible situations that could lead to a disappearance of the arctic ice pack.
