Mechanisms of Projected Changes in Thunderstorm Downburst Environments Across the United States

Geophysical Research Letters
Responses of downdraft convective available potential energy (DCAPE) to global warming were investigated using the Community Earth System Model (CESM2) under a high‐emission scenario through the year 2100.

Characteristic Analysis of the Downburst in Greely, Colorado on 30 July 2017 Using WPEA Method and X-Band Radar Observations

Atmosphere, 2018
As a manifestation of low-altitude wind shear, a downburst is a localized, strong downdraft that can lead to disastrous wind on the ground surface.

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 ...

Explainable Reinforcement Learning Framework for Autonomous Windshear Escape with Policy Distillation

Aerospace
Low-altitude micro downbursts pose a severe threat to aviation safety, yet conventional control approaches and standard deep reinforcement learning (DRL) often fail due to explicit modeling difficulties and sparse reward constraints.

Downburst prediction applications of meteorological geostationary satellites

SPIE Proceedings, 2014
A suite of products has been developed and evaluated to assess hazards presented by convective storm downbursts derived from the current generation of Geostationary Operational Environmental Satellite (GOES) (13-15). The existing suite of GOES downburst prediction products employs the GOES sounder to calculate risk based on conceptual models of ...

Generation of downburst outflow in a traditional wind tunnel using multi-blade flow control device

Advances in Wind Engineering
The thunderstorm downbursts impose a great threat to civil engineering structures and the experimentation for such nonsynoptic winds plays a significant role in the characterization and quantification of relevant aerodynamic loading.

Toward the Codification of Thunderstorm/Downburst Winds

, 2020
Abstract Non-synoptic winds often exhibit rapid changes during a short period, which may be accompanied by changes in direction. This introduces non-stationarity both in the mean and the standard deviation of wind fluctuations. Thus, design loads in non-synoptic non-stationary winds obtained from conventional analysis frameworks included

Technical Feasibility of Simulating Thunderstorm-Related Microbursts–Case Studies

Applied Sciences
The alerting of a microburst at the Hong Kong International Airport (HKIA) is currently detection-based. The technical feasibility of forecasting microbursts in an operational environment was examined in this study through four examples: three cases of a
