Thunderstorm downbursts are major cause of concern for engineering structures both on ground as well as those in air, namely aircrafts. The wind velocity profile of a thunderstorm downburst-induced wind is significantly different compared to natural atmospheric boundary layer winds. As a type of high intensity winds, thunderstorm microbursts have caused numerous structural failures around the world and have become the present research focus in structural wind engineering. The current study proposes a computational simulation method on thunderstorm downburst-induced winds. The computational fluid dynamics numerical method was employed to investigate the wind fields of thunderstorm downburst-induced wind. Unsteady simulations of wind fields were conducted using time-filtered Reynolds Averaged Navier-Stokes (RANS) numerical simulation method. The case study numerical results indicate that the wind fields present quite different characteristics at different time during the whole formation and diffusion process. The computational simulation method supplies a promising solution to study the thunderstorm downburst-induced wind characteristics for structural wind engineering.
