Evaluating the Feasibility of Phased Array Radar‐Derived Quantitative Precipitation Estimation Using the NSSL's Advanced Technology Demonstrator

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract The Weather Surveillance Radar–1988 Dopplers (WSR‐88Ds) are an operational network of S‐band, dual‐polarization radars in the United States. Currently, replacement options are being considered for the next generation of weather radars. One option is dual‐polarization phased array radar (PAR), which employs electronic beam steering to provide ...

Cobalt‐Based Metal Hybrid Encapsulated Micro‐Aluminum for Tailoring Combustion in Composite Solid Propellants

Rare Metals, Volume 45, Issue 4, April 2026.
ABSTRACT To address the issues of aluminum (Al) powder agglomeration during combustion and low oxidizer decomposition efficiency in composite solid propellants, this study utilized in situ self‐assembly technology to prepare cobalt‐based hybrid‐coated modified Al powder (Al@CZ).

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).

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 ...

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 ...

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.

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 ...

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 ...

Microbursts in the Eastern United States and Their Predictability

, 2022
Microbursts are thunderstorm outflows that impinge vertically onto the ground and then diverge horizontally. Although they represent less than 10% of severe wind reports across the eastern United States, microbursts are responsible for approximately 25 ...
