Abstract

WRF wind forecasts from four operative schemes used by OHMC (Observatorio HidroMeteorológico de Córdoba), a test scheme (WRF-E) and two daily runs with 4 km horizontal resolution were analyzed. Wind simulations were compared with measurements from eight ground stations with anemometers at 10 m high during the period from June, 2019 to June, 2020. WRF-E incorporates more vertical levels, and an activated topo_wind option. The wind speed results show that WRF overestimates wind speed at most stations and the WRF-E model reduces the BIAS and the RMSE when compared with the operational models. The wind direction analysis shows that the higher the wind speed is, the more accurate the models are. In addition, a wind gust forecasting has been implemented and evaluated in this work. Wind gust correlation coefficient values are between 0.3 and 0.6, RMSE is between 3 and 5 m/s, and a positive BIAS(<2 m/s) at most stations.

阿根廷科尔多瓦天气研究和预报（WRF）模式的风和阵风预报评估

分析了科尔多瓦气象观测中心（OHMC）使用的四个运行方案、一个测试方案（WRF-E）和两个水平分辨率为 4 千米的每日运行方案的 WRF 风预报。在 2019 年 6 月至 2020 年 6 月期间，风模拟与八个地面站 10 米高风速计的测量结果进行了比较。WRF-E 采用了更多的垂直水平，并激活了 topo_wind 选项。风速结果显示，WRF 高估了大部分站点的风速，而 WRF-E 模型与运行模型相比降低了 BIAS 和 RMSE。风向分析表明，风速越高，模型越准确。此外，这项工作还实施并评估了阵风预报。阵风相关系数值介于 0.3 和 0.6 之间，均方根误差介于 3 和 5 米/秒之间，大多数站点的 BIAS 为正值（<2 米/秒）。
