Characterization of thunderstorm downburst winds through CFD techniques
The characteristic wind field of a certain region is mostly governed by the climatology of its larger scale area. In the case of mid-latitude regions (e.g.

Simulation of the Flow Field Characteristics of a Downburst [PDF]
Wind load on a structure is usually investigated in turbulent boundary layer flow simulated in a boundary layer wind tunnel. However, the strong wind that causes damages on structures is usually transient wind, for instance, downburst wind, whose statistics are different with the general atmospheric boundary layer.

Observations of a frontal–trough merger over a wildfire, Queensland, Australia
Observations are presented of the meteorology of a frontal–trough merger in subtropical Australia which impacted a wildfire. An elevated nocturnal mixed layer above approx. 2500 m with increasing moisture with height was identified as the source of instability that resulted in the formation of elevated storms along a 300‐km frontal–trough boundary ...

Abstract Satellite precipitation retrieval is inherently an underdetermined inverse problem where additional physical constraints could substantially enhance accuracy. While previous studies have explored static (pixel‐based/spatial‐context‐based) environmental variables at discrete satellite observation times, their temporal dynamic information ...

Idealised simulation of downburst winds
Convectively driven downburst winds pose a threat to structures and communities in many regions of Australia not subject to tropical cyclones. Extreme value analysis shows that for return periods of interest to engineering design these events produce ...

Three-Dimensional Numerical Simulation of Downburst Wind Occurrded in Wuhan
Downburst is a strong downdraft generated below a cumulonimbus cloud, which hits the ground rapidly and causes significant low-level wind shear. It is a strong destructive regional weather phenomenon, which is the main reason for the transmission towers.

Experimental Modelling of Downburst and Downburst line Outflows
The outflow velocity vector fields of simulated stationary thunderstorm downbursts and downburst lines were resolved in two plane orientations, vertical and horizontal, using a dense fluid release system and Particle Image Velocimetry. Single event releases were scaled to show agreement with past studies based on radial velocity magnitude and location ...

Analysis of the Dynamics and Microphysics of a Wet Downburst Case Using Dual-Polarization Radar Data [PDF]
A significant, wet downburst affected Norman, Oklahoma, on 14 June 2011. Surface winds in excess of 35 m/s (>80 mph) and hailstones in excess of 4 cm diameter occurred during the downburst.

Downburst Flow Simulation and Evaluation of Downburst Wind Effects on Buildings
Downbursts are non-stationary, non-Gaussian, transient, localized high wind events that constitute considerable damage to structures. Five different downburst simulator designs were tested and assessed in a 1:15 small-scale replica of the Wall of Wind ...
