Model Studies of Climate Change on Monthly and Seasonal Time Scales

这个项目将测试散装的可能性， 边界层过程的参数化足以 解决大气环流模式中的空气-地面相互作用。 这种可能性将通过比较一个 全球预报模型，具有明确解析的表面， 大气传输，体积通量近似类似于 国家中心社区气候模型中使用的那些 大气研究。 测试将强调边界 南美洲安第斯山脉两侧的层流。 这项工作可能会改进和有效地建立气候模型 空气-地面交换是主要的过程 重要性

This project will test the possibility that bulk parameterizations of boundary layer processes are adequate to resolve air-surface interactions in general circulation models. This possibility will be tested by comparing results from a global forecast model, with explicitly resolved surface to atmosphere transfer, to the bulk flux approximations similar to those used in the Community Climate Model of the National Center for Atmospheric Research. The tests will emphasize boundary layer flows that flank the South American Andes Mountain ranges. This work may lead to improved and efficient modelling of climate processes in which air-surface interchanges are of principal importance.
