Under this award, Dr. Betts will pursue a wide range of problems involving primarily the thermodynamics of atmospheric energy and water interactions from the surface through the troposphere, in support of programs such as the Global Energy and Water Cycle Experiment Continental-Scale International Project (GCIP) and the Boreal Forest Ecosystem-Atmosphere Study (BOREAS). The overarching objective is to improve the surface boundary condition over land in large-scale models. At present, forecast and climate models have serious deficiencies in their physical parameterizations, particularly in the modeling of energy and water transports at the earth's surface (more so over land than over the ocean), and in the coupling of convective processes to the large-scale dynamic and radiation fields. The principal investigator will tackle these issues by first analyzing observations from several field programs and then using them to test and develop physical parameterizations in large-scale models. Operational forecast models will be used primarily so that the research directly benefits the forecasting of weather on timescales of a few days, as well as the global model data bases, which are used for climate studies. This research is supported under NSF's Water and Energy: Atmospheric, Vegetative, and Earth Interactions (WEAVE) Program.***

根据该奖项，Betts博士将研究广泛的问题，主要涉及从地表到对流层的大气能量和水相互作用的热力学，以支持全球能源和水循环实验大陆尺度国际项目(GCIP)和北方森林生态系统-大气研究(BOREAS)等项目。总体目标是在大尺度模式中改善陆地上的地面边界条件。目前，预报和气候模式在物理参数化方面存在严重不足，特别是在模拟地球表面的能量和水传输(陆地上比海洋上更严重)，以及对流过程与大尺度动力场和辐射场的耦合方面。首席研究人员将首先分析几个现场项目的观测结果，然后利用它们在大型模型中测试和开发物理参数，从而解决这些问题。将主要使用业务预报模型，以便研究直接惠及几天时间尺度上的天气预报，以及用于气候研究的全球模型数据库。这项研究得到了美国国家科学基金会水与能量：大气、植物和地球相互作用(WEAVE)计划的支持。
