Aerodynamic characteristics of the train traversing the thunderstorm downburst wind field
To investigate the aerodynamic characteristics of the high-speed train as it traverses the thunderstorm downburst wind, a special test device was used to simulate the thunderstorm downburst wind field.

An observational study of a circular gust front over the Yangtze Delta, China
Concentric gust fronts are formed when a thunderstorm’s downdraft reaches the ground and the outflow from the cold pool spreads uniformly outwards into the surrounding warm and humid air mass. Observational evidence presented here show the case of narrow‐band echoes forming a ring around a thunderstorm.

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.

The Bayesian sinking in Porticello: a predictable convective windstorm?
The meteorological phenomenon that led to the Bayesian yacht sinking in Sicily at 0206 utc on 19 August 2024 is here investigated. A thunderstorm occurred during the sinking, but uncertainties exist regarding whether a waterspout or a downburst affected the ship. An in‐depth analysis of available observations highlighted that the ship was likely struck

Abstract A new high‐spatial resolution camera on the International Space Station used OH nightglow in the H‐band to image the ground at an ∼ ${\sim} $70 m pixel footprint over an ∼ ${\sim} $280 km swath and maintained this resolution during its 1.5 s exposure.

Despite most weather-related failures of high-voltage transmission lines (HVTLs) being attributed to the downbursts accompanied by heavy rainfall, research works mainly focused on the behaviors of the high-voltage transmission tower-line structures under

Effects of the urban land use on a severe convective windstorm
Numerical simulations with the Weather Research and Forecasting model coupled with the Building Effect Parametrization–Building Energy Model multilayer canopy model were conducted to investigate the impact of urban land use on a severe convective windstorm in Milan, northern Italy, on July 25, 2023.

Idealised simulation of downburst winds [PDF]
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 ...

A study of the 23 October 2022 southern England damaging MCS
During the afternoon of 23 October 2022, a mesoscale convective system (MCS) developed and intensified over the English Channel and tracked north‐northeastward into southern England, producing widespread damaging winds and at least three moderate to strong tornadoes in Hampshire.

Reconstruction of near-surface tornado wind fields from forest damage [PDF]
Tornado intensity is usually inferred from the damage produced. To foster postevent tornado intensity assessments, the authors present a model to reconstruct near-surface wind fields from forest damage patterns. By comparing the structure of observed and
