Evaluation of the ETA Model Over the Western United States

小行星9318491 最近的研究表明，国家气象中心的区域预报模型，即“ETA”模型，在预测夏季亚利桑那州中部的强降水爆发方面做得很差。 主要研究人员认为，这可能是由于模型中处理复杂地形上某些物理过程的方式。 因此，他们将在美国西部对该模式的技巧进行系统的评估，作为天气形势和季节的函数。 他们计划在研究的这一部分中采用最近一系列实地实验的观测结果，西南地区季风项目（SWAMP）。 此外，他们将评估ETA模型在复杂地形区域的物理参数化。在执行这一项目时，PI将与国家气象中心的工作人员和国家气象局西部地区的业务气象学家密切合作。 该项目作为NSF/NMC数值天气预报联合计划的一部分得到支持。 ***

9318491 Horel Recent studies have shown that the National Meteorological Center's regional forecast model, known as the "ETA" model, does poorly in predicting heavy precipitation outbreaks over central Arizona during the summer. The principal investigators believe that this may be due to the way in which certain physical processes over complex terrain are handled in the model. Accordingly, they will undertake a systematic evaluation of the skill of this model over the western United States as a function of synoptic weather situation and season. They plan to employ observations from a series of recent field experiments, the Southwest Area Monsoon Project (SWAMP), in this part of the study. In addition, they will evaluate the ETA model's physical parameterizations in regions of complex terrain. In carrying out this project, the PIs will work closely with personnel at NMC and operational meteorologists in the Western Region of the National Weather Service. This project is supported as part of the NSF/NMC Joint Program in Numerical Weather Prediction. ***
