Local strong winds such as tornadoes and downbursts are rare in terms of measured wind speed data due to their rapid formation and strong destructive power.

Abstract Large eddy simulations (LES) can aid the prediction of wind loading on buildings, provided that representative inflow turbulence properties are prescribed. This study conducts LES to assess the sensitivity of the mean, root mean square (rms) fluctuation, and peak pressure coefficients (Cp) on building surfaces to the uncertainties in the ...

A slice of research pertinent to the analytical or empirical models of downburst winds was available, but the current validation was usually based on sampled wind velocities at several typical positions in the experimental measurements rather than the ...

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 ...

Applications of vortex gas models to tornadogenesis and maintenance [PDF]
Processes related to the production of vorticity in the forward and rear flank downdrafts and their interaction with the boundary layer are thought to play a role in tornadogenesis.

Numerical Modeling of Thunderstorm Downbursts and Downburst Lines [PDF]
Large eddy simulations have been used to compare the near surface outflow of the commonly used transient impinging jet to that of the physically realistic cooling source downburst model. This has shown that the transient impinging jet is incapable of capturing the buoyancy driven features of an actual downburst, due to its non-physical forcing ...

The evolution of wind gusts is difficult to observe because gusts are short‐lived phenomena that can originate at higher altitudes. During the Field Experiment on Sub‐mesoscale Spatio‐Temporal Variability in Lindenberg (FESSTVaL), novel ground‐based remote‐sensing methodologies were applied to measure wind with Doppler lidars in order to provide the ...

A simple, analytic 3-dimensional downburst model based on boundary layer stagnation flow [PDF]
A simple downburst model is developed for use in batch and real-time piloted simulation studies of guidance strategies for terminal area transport aircraft operations in wind shear conditions.
