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博士将提出各种各样的问题，主要涉及大气能量和水相互作用的热力学，从地表到对流层的热力学，以支持诸如全球能源和水循环实验诸如大陆大陆规模国际项目（GCIP）和钻石森林森林生态系统-Atmosphere-Atmosphere研究（Boreas）等计划。 总体目标是改善大型模型中土地上的地面边界条件。 目前，预测和气候模型在其物理参数化方面存在严重的缺陷，尤其是在地球表面的能量和水传输的建模（比海洋上的土地上比在海洋上更大），以及对流过程与大型动态和辐射场的耦合。 首席研究人员将通过首先分析几个现场计划的观察结果，然后使用它们来测试和开发大型模型中的物理参数化来解决这些问题。 运营预测模型将主要使用，以使研究直接受益于几天的时间尺度的天气以及用于气候研究的全球模型数据基础。 这项研究得到了NSF的水和能源的支持：大气，营养和地球相互作用（编织）计划。***
