Abstract

Focusing on the persistent sand-dust weather in Northwest China, this study investigates the impact of wind farm wakes on dust transport using a coupled sand and dust numerical model (WRF-WFP-DUST). The model integrates a mesoscale meteorological model with a wind farm parameterization scheme. The research takes the typical flat-terrain wind farm cluster in Alxa League, Inner Mongolia Autonomous Region, as the study object and simulates a regional sandstorm event in March 2021.The findings reveal: A significant wind speed attenuation effect occurs within the wind farm cluster area. The degree of attenuation exhibits distinct variation characteristics depending on the number of wind farms arranged in tandem. The maximum wind speed attenuation (38.5%) occurred at the third wind farm within the cluster. Sand-dust concentrations display different characteristics in the horizontal and vertical directions. Downstream of the wind farms, along the wake direction, the dust distribution exhibits distinct symmetry. When the number of tandem wind farms reaches three, a substantial influence on sand and dust transport occurs at the hub height plane, where the concentration decreases by 12.2%. The hindering effect is slightly less pronounced at the upper tip height plane and the lower tip height plane, with concentration reductions of 10.9% and 7.4%, respectively.
