Surface and Boundary Layer Interactions of Energy and Water

根据该奖项，贝茨博士将研究从陆地表面到对流层的大气能量和水相互作用的热力学。目前，预报和气候模式在物理参数化方面存在严重不足，特别是在陆地表面能量和陆地输运的模拟方面，以及在地表和边界层与对流过程的耦合方面。首席研究员将通过分析各种实地项目的观察结果来解决这些问题，然后使用它们来诊断和纠正大规模模型中物理参数化的错误。将使用业务预报模式，主要是欧洲中期预报中心（ECMWF）模式，因此这项研究直接有利于从几天到季节时间尺度的天气预报。此外，这项研究将有助于改进业务预报中心所作的全球再分析，这些预报中心是气候研究的关键数据库。本研究的目标直接有助于美国国家科学基金会在USGCRP下的WEAVE项目的目标和国际全球能源和水循环实验（GEWEX）努力的目标。

Under this award, Dr. Betts will investigate the thermodynamics of atmospheric energy and water interactions from the land surface to the troposphere. At present, forecast and climate models have serious deficiencies in their physical parameterizations, particularly in the modeling of energy and land transports at the land surface, and in the coupling of the surface and boundary layer to convective processes. The principal investigator will address these issues by analyzing observations from various field programs, and then using them to diagnose and correct errors in the physical parameterizations in large-scale models. Operational forecast models will be used, primarily the European Centre for Medium-Range Forecasts (ECMWF) model, so that this research directly benefits the forecasting of weather on time-scales from a few days out to the seasonal time-scale. In addition, the research will help to improve the global reanalyses produced by operational forecast centers which are key databases for climate studies. The goals of this research contribute directly to the objectives of NSF's WEAVE program under the USGCRP and to the goals of the International Global Energy and Water Cycle Experiment (GEWEX) effort.
