Reduced ERA‐I Forecasting Skill During Forbush Decreases

Geophysical Research Letters
Correlations between week‐long cosmic ray flux perturbations and terrestrial cloud cover have previously been identified. Still, uncertainty persists on whether the cloud response is due to a physical link involving cosmic rays or caused by random ...

On the Magnetosphere‐Ionosphere Coupling During the May 2021 Geomagnetic Storm

Space Weather, 2022
On 12 May 2021 the interplanetary doppelgänger of the 9 May 2021 coronal mass ejection impacted the Earth's magnetosphere, giving rise to a strong geomagnetic storm.

Forbush Decrease Data with a Simple Model

, 2006
On October 28, 2003 an earthward-directed coronal mass ejection (CME) was observed from SOHO/LASCO imagery in conjunction with an X17 solar flare. The CME, traveling at nearly 2000 km/s, impacted the Earth on October 29, 2003 causing ground-based particle detectors to register a counting rate drop known as a Forbush decrease.

Starving for Data: Eating Disorders Prevalence and Research Gaps in Southern Africa

International Journal of Eating Disorders, Volume 59, Issue 4, Page 682-699, April 2026.
ABSTRACT Objective Studies reporting prevalence estimates of eating disorders in Southern Africa are scarce. To fill this gap, the present Research Forum reviews existing literature on the prevalence of eating disorders, including as assessed by clinical interviews, screeners, and self‐reported behaviors, among individuals in Southern Africa.

Shock drift mechanism for Forbush decreases

The Astrophysical Journal, 1990
Consideration is given to the way in which Forbush decreases can arise from variable drifts in nonuniform shocks, where the variation in shock strength along the shock front causes both the shock drift distance and the energy gain to become variable.

Observation of Forbush Decreases and GLE‐74 Recorded During Ground‐Level Neutron Monitoring Survey From Various Sites

Space Weather, Volume 24, Issue 4, April 2026.
Abstract Ground‐level neutron monitors (NMs) are essential tools for monitoring space weather events, including the detection and alerting of ground‐level enhancement (GLE) events. This study presents findings from a neutron monitoring survey using two compact N50L neutron slab‐based subsystems deployed across various field sites in the United Kingdom (

High-energy cosmic ray intensity increase of nonsolar origin and the unusual Forbush decrease of August 1972

, 1974
A series of spectacular cosmic ray events, which included two relativistic solar particle enhancements and three major Forbush decreases, was registered by ground-based cosmic ray monitors beginning on August 4, 1972.

Estimation of Global Increase of Radiation Dose Rates During the Ground Level Enhancement on 11–12 November 2025 Using WASAVIES

Space Weather, Volume 24, Issue 4, April 2026.
Abstract WArning System for AVIation Exposure to Solar energetic particles (WASAVIES) is a physics‐based nowcasting system designed to support warning operations for aviation exposure to solar energetic particles (SEPs) by providing near‐real‐time global SEP dose‐rate estimates.

Recurrent and sporadic Forbush decreases during solar cycles 23–24

Solar-Terrestrial Physics, 2019
A comparison has been made between recurrent (associated with high-speed streams from coronal holes) and sporadic (caused by interplanetary coronal mass ejections (ICMEs)) Forbush decreases (FDs) in solar cycles 23 and 24 (as well as in the maxima of ...

Report of Cosmic-Ray Neutron Observation in the 9th Japanese Antarctic Research Expedition 1968-1969 (Reports of the Japanese Antarctic Research Expedition)

Antarctic Record, 1971
From February 1968 to January 1969, cosmic ray nucleonic component was observed at Syowa Station, Antarctica (69°00'S, 39°35'E), using a duplicate set of 5-NM-64 super neutron monitor with a multiplicity meter.
