WRF-Solar是为太阳能应用而设计的天气研究和预报（WRF）模型的特定配置和增强。最近对WRF模型的升级有助于使模型适合于太阳能预测，包括1）诊断太阳能产业所需的内部相关大气参数的发展，2）改进气溶胶辐射反馈的表示，3）纳入云-气溶胶相互作用，以及4）改进云辐射反馈。WRF-太阳能的发展与晴空预报模型性能的全面表征一起提出。性能进行了评估与数值实验，使用一系列不同的外部和内部处理的大气气溶胶，包括模型推导的气溶胶光学厚度和时间演变的气溶胶光学特性的再分析产品的气候。在晴空条件下，为了获得地面短波辐照度分量的准确估计，显然有必要考虑大气气溶胶的影响。与WRF模型的标准版本相比，全球水平辐照度、直接法向辐照度和漫射辐照度分别提高了58%、76%和83%。结果表明，WRF-Solar模型是一个改进的数值工具的研究和应用，以支持太阳能。
WRF-Solar is a specific configuration and augmentation of the Weather Research and Forecasting (WRF) Model designed for solar energy applications. Recent upgrades to the WRF Model contribute to making the model appropriate for solar power forecasting and comprise 1) developments to diagnose internally relevant atmospheric parameters required by the solar industry, 2) improved representation of aerosol–radiation feedback, 3) incorporation of cloud–aerosol interactions, and 4) improved cloud–radiation feedback. The WRF-Solar developments are presented together with a comprehensive characterization of the model performance for forecasting during clear skies. Performance is evaluated with numerical experiments using a range of different external and internal treatment of the atmospheric aerosols, including both a model-derived climatology of aerosol optical depth and temporally evolving aerosol optical properties from reanalysis products. The necessity of incorporating the influence of atmospheric aerosols to obtain accurate estimations of the surface shortwave irradiance components in clear-sky conditions is evident. Improvements of up to 58%, 76%, and 83% are found in global horizontal irradiance, direct normal irradiance, and diffuse irradiance, respectively, compared to a standard version of the WRF Model. Results demonstrate that the WRF-Solar model is an improved numerical tool for research and applications in support of solar energy.
