Super-high-resolution numerical simulations on the wind environment in neighborhoods have been a hot research area in urban meteorology. In this study, a computational fluid dynamics model based on large-eddy simulation was utilized to simulate the climatic wind environment in Longhu Community in Chongqing, and the impacts of local building configurations on the fine-scale structures of the wind field was investigated. Results show that complex underlying surfaces played an important role in regulating local circulations. The strong winds were mainly found over open spaces and at broad streets parallel to the background inflow. The overall wind speed in summer was larger than that in other seasons and could reach a magnitude of 0.8 m/s. Different building configurations led to different patterns of local wind fields. The isolated tall building resulted in strong downward motions and winding flows at the windward side of the building, where strong winds frequently occurred. The scattered low buildings had little impact on the local inflow, resulting in a wind field with a homogeneous pattern. The densely built tall complex with an enclosing shape greatly blocked the wind, which led to a relatively weak wind speed in the vicinity and was unfavorable for pollutant dispersion.
