Semiempirical Models of Speedup Effect for Downburst Wind Field over 3-D Hills
Atmosphere, 2023 Downbursts occur frequently in mountainous regions, such as the southwest of China, and causing extensive damage to engineering structures. While some researchers have developed semiempirical models for the speedup effect, most are based on the wind ...
