Performance of windshear/microburst detection algorithms using numerical weather prediction model data for selected tropical cyclone cases

Atmospheric Science Letters, 2023
Three windshear/microburst detection algorithms are used operationally at the Hong Kong International Airport. Their performance is studied in the present article by assuming the availability of the complete set of meteorological data from numerical ...

BARREL Observations of Microburst Events With a Slowly‐Varying Component

Geophysical Research Letters
Electron microburst precipitation has been shown to have significant potential for depletion of the outer radiation belt. We present observations from the Balloon Array for Radiation belt Relativistic Electron Losses (BARREL) of six (five unique and one ...

DART: A Dual Aperture Relativistic Electron Telescope for Smallsats

Journal of Geophysical Research: Space Physics, Volume 131, Issue 3, March 2026.
Abstract The precipitation of particles into the Earth's atmosphere is a primary loss mechanism of the radiation belt for which many unknowns remain. With the growing number of space mission concepts to solve them, less expensive alternatives such as CubeSats are being used.

Physical simulation of atmospheric microbursts [PDF]

Journal of Geophysical Research: Atmospheres, 2014
AbstractA laboratory simulation of atmospheric microbursts is presented. The physical model of the atmospheric phenomenon is reproduced at a reduced scale in a rotating tank (TURLab, Italy), the similitude is based on the Froude number. Different experiments were carried out varying the Rossby number, and the analysis of four significant cases is ...

Bursty Precipitation of Relativistic Electrons Unveiled by CIRBE/REPTile‐2 Measurements and Their Physical Implications

AGU Advances, Volume 7, Issue 1, February 2026.
Abstract Energetic electron precipitation plays a pivotal role in shaping Earth's radiation belt dynamics and drives significant physical and chemical changes in the upper atmosphere. However, the detailed mechanisms governing the loss of relativistic electrons have remained unclear, largely due to the limited energy coverage and coarse resolution of ...

Evidence of Microbursts Observed Near the Equatorial Plane in the Outer Van Allen Radiation Belt

Geophysical Research Letters, 2018
We present the first evidence of electron microbursts observed near the equatorial plane in Earth's outer radiation belt. We observed the microbursts on 31 March 2017 with the Magnetic Electron Ion Spectrometer and Radiation Belt Storm Probes Ion ...

Test Particle Simulations of Dual‐Component Microbursts Observed by BARREL: Effects of Atmospheric Backscattering and Chorus Elements

Journal of Geophysical Research: Space Physics, Volume 131, Issue 2, February 2026.
Abstract Electron microbursts are among the most important loss mechanisms for energetic electrons in the Earth's radiation belts and are often driven by wave‐particle interactions with discrete chorus wave elements. Observations from the Balloon Array for Radiation‐belt Relativistic Electron Losses (BARREL) mission have revealed microburst events with

Convective environments leading to microburst, macroburst and downburst events across the United States

Weather and Climate Extremes, 2022
Downbursts are strong downdrafts of negatively buoyant air associated with convective storms and are capable of producing severe near-surface winds. Microbursts and macrobursts are subcategories of downbursts with the horizontal extent of damaging winds ...
