摘要

Lately, the use of wind farms in Romania to generate electricity is growing. Wind turbines cause contamination of weather radar signals that is under certain conditions difficult to distinguish from weather echoes. Areas of false reflectivities, mean radial velocity and spectrum width data may appear in base data displays. These artifacts can affect and confuse weather forecasters and other radar data users. Since data from weather radars are key components in the decision making process of issuing severe weather warnings and nowcasting forecasts, and numerical weather models assimilation, this paper documents and addresses some of the impacts of wind farms on radar data. The WSR-98D radar at Medgidia was chosen for this study. A combination of low-resolution radar products and high-resolution data was used to document the impacts. The data have been used to construct a climatology of wind farm echo observation and to develop a GIS-based mitigation algorithm. The results of the study highlight the potential impacts of the wind farm echoes and the performance of the correction algorithm. The operational implementation of the mitigation algorithm was proposed.
