采用天气研究和预报(WRF)模式作为嵌套区域气候模式，研究了巨型风电场对美国东部三分之二地区暖季降水的影响。WRF的边界条件由NCEP/NCAR(国家环境预测中心/国家大气研究中心)62年来的全球再分析提供。在该模型中，中西部风电场的存在，无论是大型的还是小型的，都可以对一个季节的天气和降雨量产生巨大的影响，这与已知的长期天气预报对初始条件的敏感性是一致的。对气候的影响没有那么强烈。在62个暖季的平均降水中，风电场周围和东南部的多州地区的降水有统计上显著的增加1.0%。
The Weather Research and Forecasting (WRF) model is employed as a nested regional climate model to study the effect of a giant wind farm on warm-season precipitation in the eastern two-thirds of the USA. The boundary conditions for WRF are supplied by 62 years of NCEP/NCAR (National Center for Environmental Prediction/National Center for Atmospheric Research) global reanalysis. In the model, the presence of a mid-west wind farm, either giant or small, can have an enormous impact on the weather and the amount of precipitation for one season, which is consistent with the known sensitivity of long-term weather forecasts to initial conditions. The effect on climate is less strong. In the average precipitation of 62 warm seasons, there is a statistically significant 1.0% enhancement of precipitation in a multi-state area surrounding and to the south-east of the wind farm.
