Advances in Civil Engineering, Volume 2025, Issue 1, 2025.This study unveils novel vortex memory mechanisms governing unsteady aerodynamics of streamlined bridge decks under transient winds via CFD simulation with the SST k‐ω model (the acceleration magnitudes were set as ±5 m/s2 and ±10 m/s2, respectively).

Advances in Meteorology, Volume 2025, Issue 1, 2025.A microburst encounter near the ground was documented for the first time at Hong Kong International Airport (HKIA). Analysis of the flight data for the concerned aircraft revealed that it passed through at least three small vortices within the band of heavy rain. Most notably, the aircraft experienced an updraft–downdraft vertical velocity couplet when

Feasibility study of a procedure to detect and warn of low level wind shear [PDF]
A Doppler radar system which provides an aircraft with advanced warning of longitudinal wind shear is described. This system uses a Doppler radar beamed along the glide slope linked with an on line microprocessor containing a two dimensional, three ...

Problems pilots face involving wind shear [PDF]
, 1977 Educating pilots and the aviation industry about wind shears presents a major problem associated with this meteorological phenomenon. The pilot's second most pressing problem is the need for a language to discuss wind shear encounters with other pilots ...

Numerical Modeling of Thunderstorm Downbursts and Downburst Lines [PDF]
, 2010 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 ...

Investigation of Coastal Winds and Turbulence Characteristics Using Doppler Lidar
Journal of Geophysical Research: Atmospheres, Volume 129, Issue 19, 16 October 2024.Abstract Sea ports play a major role in the transport of goods worldwide, and knowledge of wind characteristics in these areas is vital to maintaining safety. However, coastal wind flow can be highly complex and turbulent, necessitating additional analysis.

Assessing Downburst Kinematics Using Video Footage Analysis
AtmosphereMeasurements of downburst outflows using standard meteorological instruments (e.g., anemometers) are rare due to their transient and localized nature. However, video recordings of such events are becoming more frequent.

A novel empirical model for vertical profiles of downburst horizontal wind speed
Wind Energy, Volume 27, Issue 4, Page 403-424, April 2024.Abstract This study proposes an empirical model for preliminary wind‐resist design of downburst flow. Existing empirical models were compared with field data and found to underpredict horizontal wind speed below the height corresponding to the maximum radial velocity, due to the neglect of viscous effects and the evolution of vertical wind profiles ...
