The Predictability of the Southern England 23 October 2022 Severe Downbursts

Atmospheric Science Letters, Volume 27, Issue 3, March 2026.
Accurate prediction of damaging straight‐line wind events from convection helps keep people safe. Using four regional ensemble prediction systems, we determine the predictability of the different aspects of the microburst wind potential index (left), which can be used to estimate the spread in expected downburst speed (right).

Simulation of Atmospheric Microbursts Using a Numerical Mesoscale Model at High Spatiotemporal Resolution

Journal of Geophysical Research: Atmospheres, 2020
Atmospheric microbursts are low‐level meteorological events that can produce significant damage on the surface and pose a major risk to aircraft flying close to the ground.

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.

Analysis on Multi-Factor Synergistic Hazards Mechanism of Wet Micro-Downburst: a Multi-Source Data Fusion Analysis Based on Passenger Vessel Capsizing Accident in Qianxi, Guizhou on 4 May 2025 [PDF]

Natural Hazards and Earth System Sciences
The research on the multi-factor synergistic disaster-causing mechanism of wet microbursts, constrained by the scarcity of monitoring data, constitutes a crucial bottleneck restricting the early warning and prevention of major accidents such as water ...

What makes the Crab pulsar shine?

, 2007
Our high time resolution observations of individual pulses from the Crab pulsar show that the main pulse and interpulse differ in temporal behavior, spectral behavior, polarization and dispersion. The main pulse properties are consistent with one current

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 ...

Dynamical critical scaling of electric field fluctuations in the greater cusp and magnetotail implied by HF radar observations of F-region Doppler velocity [PDF]

Annales Geophysicae, 2006
Akasofu's solar wind ε parameter describes the coupling of solar wind energy to the magnetosphere and ionosphere. Analysis of fluctuations in ε using model independent scaling techniques including the peaks of probability density ...

Microburst precipitation phenomena.

Journal of geomagnetism and geoelectricity, 1978
Auroral zone microburst electron precipitation is reviewed. It can be shown from existing data that microbursts represent a major precipitation form on the dayside magnetosphere. Balloon X-ray data indicate that microbursts are periodic and they are small-scaled. Rocket and sattellite data indicate that microbursts may consist of substructures and that

Observation of Downburst Associated with Intense Thunderstorms Encountered by an Aircraft at Hong Kong International Airport

Applied Sciences
In situ observational data from aircraft within microbursts is rather rare in Hong Kong, and such a case is documented in this paper by comparison with the large amount of meteorological data in the vicinity of Hong Kong International Airport, in ...

Global Morphology of Chorus Waves in the Outer Radiation Belt and the Effect of Geomagnetic Activity and fpe ${f}_{pe}$/fce ${f}_{ce}$

Journal of Geophysical Research: Space Physics, Volume 131, Issue 2, February 2026.
Abstract Whistler‐mode chorus waves play a key role in driving radiation belt dynamics by enabling both acceleration of electrons to relativistic energies as well as their loss into the atmosphere via pitch‐angle scattering. The ratio between the electron plasma frequency (fpe ${f}_{pe}$) and the electron gyrofrequency (fce ${f}_{ce}$) significantly ...
