A New Joint Weather Research and Prediction (WRF) Model

这项合作研究工作将有助于开发一种新的天气研究和预报(WRF)模式，该模式将推动中尺度数值天气预报的最新水平，并提供一个通用的模拟系统，供研究和业务使用。除了这一奖项为俄克拉荷马大学风暴分析和预测中心提供的支持外，其他合作者还包括：国家大气研究中心中、小尺度气象部；国家海洋和大气管理局(NOAA)国家环境预测中心(NCEP)；以及NOAA预报系统实验室(FSL)。WRF模式正在设计中，以提供一个高分辨率的预报系统，将准确地预测大范围内的重要天气，特别是降水系统。它将包含模型求解器的高级数值，几个新的原型将作为候选架构进行评估。该模型的并行实现正在单一源代码中设计，该源代码在不同的计算机体系结构中灵活而高效。将为WRF开发一个新的变分数据同化系统，其中将包括较小尺度的观测，如多普勒雷达和中间网络数据。在模型物理学方面，将积极争取更广泛的研究界参与开发和评估用于高分辨率应用的改进的物理学。在三年的时间内，将提供一个完整的、研究质量高的WRF模型系统，并支持其作为社区研究模型广泛使用。在本建议所涉期间之后，将继续发展，预计世界粮食安全框架模式将在大约五年内成为替代区域业务模式的候选模式。通过联合开发和使用WRF，该项目有可能显著加强研究科学家和运筹学家之间的互动，特别是简化研究成果转化为业务的过程。

This collaborative research effort will contribute to the development of a new Weather Research and Forecasting (WRF) Model that will advance the state of the art in mesoscale numerical weather prediction and provide a common modeling system for use in both research and operations. In addition to the support provided to the University of Oklahoma's Center for Analysis and Prediction of Storms under this award, the other collaborators include: the National Center for Atmospheric Research Mesoscale and Microscale Meteorology Division; the National Oceanic and Atmospheric Administration (NOAA) National Centers for Environmental Prediction (NCEP); and the NOAA Forecast Systems Laboratory (FSL).The WRF Model is being designed to provide a high-resolution forecast system that will accurately predict significant weather over a broad range of scales, with particular emphasis on precipitation systems. It will contain advanced numerics for the model solver, and several new prototypes will be evaluated as candidate architectures. A parallel implementation for the model is being designed within a single source code that is flexible and efficient across a diverse spectrum of computer architectures. A new variational data assimilation system will be developed for WRF that will include observations at smaller scales, such as Doppler radar and mesonetwork data. In the area of model physics, the involvement of the broader research community will he actively solicited in developing and evaluating improved physics for high-resolution applications.Within the three year time frame a full physics, research quality WRF modeling system will be made available and supported for broad use as a community research model. Development will continue beyond this proposal period, with the expectation that the WRF Model will become a candidate for replacing the regional operational models in about five years. Through the joint development and use of WRF, this project has the potential to enhance significantly the interactions between research and operational scientists, and in particular, to streamline the transfer of research advances into operations.
