Abstract

A high-resolution wind speed estimation method (HRWSEM) is proposed for urban surfaces based on vertical stratification downscaling technique, and the usability of the method is evaluated by applicated in Shanghai as an example. The HRWSEM integrates the wind speed variation characteristics at different heights within the atmospheric boundary layer in the vertical direction and the influence of effective roughness on wind speed at different heights in the horizontal direction. It is not only able to better characterize the refined distribution characteristics of urban wind speed, but also the influence of large-scale complex terrain under different wind directions. In addition, it also can better simulate the temporal variation characteristics of wind speed and has good consistency with the observation.
