Mesoscale Numerical Simulation of a Downburst

Abstract:

Downburst winds with their great destructive power have caused destruction of numerous engineering structures around the world. Study on wind loadings of downburst is essential and hot in the wind engineering field. But various meteorological factors of downburst formulation are not considered in existing research methods in the wind engineering field. In this paper, a downburst case is simulated by using a numerical weather prediction model ARPS from the meteorological point of view. The simulation results successfully reproduce the wind field characteristics while downburst occurring. The study in this paper aims at introducing meteorological method and knowledge to the wind engineering field, and the results of mesoscale numerical simulation in this study will be used in the small-scale numerical simulation as initial data in further study.
