CLIMATHUNDERR: experimental database of buoyancy-driven downbursts

Earth System Science Data
Abstract. Thunderstorm downbursts are windstorms due to intense negatively-buoyant flows produced beneath cumulonimbus clouds. Their study has recently attracted significant scientific and media attention due to the current and projected impacts of climate change.

Added Value of Environmental Variables for Satellite Precipitation Retrieval: A Temporal Coevolution Perspective and a Machine Learning Integration Assessment

Geophysical Research Letters, Volume 52, Issue 11, 16 June 2025.
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 ...

Wind load impact on tall building facades: damage observations during severe wind events and wind tunnel testing

Frontiers in Built Environment
As global urbanization accelerates, the construction of tall buildings has surged, becoming a defining feature of modern cityscapes. Tall buildings, while contributing to economic growth and urban development, face substantial risks from extreme wind ...

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 ...

Exploring the Feasibility of Using Commercially Available Vertically Pointing Wind Profiling Lidars to Acquire Thunderstorm Wind Profiles

Frontiers in Built Environment, 2019
While multiple types of remote sensing instruments have been used to investigate wind profiles associated with thunderstorms, the use of profiling Lidars (LIght Detection And Ranging) has been mostly limited to the wind energy sector.

A refined empirical model of steady-state downburst based on high-resolution wind speed data obtained from wind tunnel tests

Advances in Wind Engineering
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 ...
