Comparative study of tall building response to synoptic and non-synoptic wind action

REM: International Engineering Journal
Until the beginning of the 21st Century, the characteristics of wind for purposes of structural analysis and design, as reflected in wind codes worldwide, were based on the behavior of wind currents in the vicinity of the ground surface observed in so ...

Review of Wind Field Characteristics of Downbursts and Wind Effects on Structures under Their Action

Buildings
Downbursts belong to sudden, local, and strong convection weather, which present significant destruction for structures. At any given time, there are approximately 2000 thunderstorms occurring on the Earth.

Effect of surface roughness on large-scale downburst-like outflows

, 2022
Downbursts are negatively buoyant descending winds coming from thunderstorm clouds that spread on the horizontal upon impinging the ground. Surface roughness is known to govern the characteristics of synoptic-scale atmospheric boundary layer (ABL) winds.

CFD and experimental modelling of an impinging jet for thunderstorm downburst simulation

, 2006
A thunderstorm downburst in its simplest form can be modelled as a steady flow impinging air jet. Although this simplification neglects some important atmospheric and physical parameters it has proven to be a useful tool for understanding the kinematics ...
