The Effect of Forbush Decreases on the Polar-Night HOx Concentration Affecting Stratospheric Ozone

open access: yesFrontiers in Earth Science, 2021
It is well-known that energetic particle precipitations during solar proton events increase ionization rates in the middle atmosphere enhancing the production of hydrogen oxide radicals (HOx) involved in the catalytic ozone destruction cycle.

Investigating Effects of Solar Proton Events and Forbush Decreases on Ground‐Level Potential Gradient Recorded at Middle and Low Latitudes and Different Altitudes

open access: yesSpace Weather, 2022
High‐energetic charged particles, such as solar protons, and phenomena such as Forbush decreases are eligible candidates to affect the global electric circuit.

SOLAR ACTIVITY AND EARTH SEISMICITY

open access: yesSolar-Terrestrial Physics, 2021
Using the results of continuous long-term observations over 50 years (including solar cycles 20–24), we study the relationship between Earth’s seismicity and solar activity.

Forbush Decrease Characteristics in a Magnetic Cloud

open access: yesSpace Weather, 2020
Based on the new mechanism, the Forbush decrease characteristics are calculated for eight magnetic cloud types. It is shown that the Forbush decrease amplitude does not depend on the magnetic cloud type, while the anisotropy strongly does.

Solar Energetic Particle Events and Forbush Decreases Driven by the Same Solar Sources

open access: yesUniverse, 2022
The characteristics of Forbush decreases (FDs) and solar energetic particle (SEP) events driven by the same solar source (i.e., coronal mass ejection and associated solar flare) are investigated.

Topside ionosphere during solar cosmic ray bursts and Forbush decreases in galactic cosmic rays

open access: yesSolar-Terrestrial Physics, 2022
The paper considers the behavior of the upper ionosphere at heights of the F2 layer during Forbush decreases in galactic cosmic rays (GCR FDs) and solar cosmic ray (SCR) bursts.

Severe geomagnetic storms and Forbush decreases: interplanetary relationships reexamined [PDF]

open access: yesAnnales Geophysicae, 2010
Severe storms (Dst) and Forbush decreases (FD) during cycle 23 showed that maximum negative Dst magnitudes usually occurred almost simultaneously with the maximum negative values of the Bz component of interplanetary magnetic field B, but the maximum ...

Low Latitude Lightning Activity Responses to Cosmic Ray Forbush Decreases

open access: yesGeophysical Research Letters, 2020
The relation between low latitude lightning activity and Forbush decreases (FDs) of galactic cosmic rays was studied, with flash rates observed by the Lightning Image Sensor aboard the Tropical Rainfall Measuring Mission satellite and FDs selected from ...

Spectral Features of Forbush Decreases during Geomagnetic Storms

open access: yesJournal of Atmospheric and Solar-Terrestrial Physics, 2023
Geomagnetic storms and Forbush decreases (FD) on Earth are primarily caused by interplanetary coronal mass ejections (ICMEs) and stream/corotating interaction regions (SIRs/CIRs) originating in the Sun, which are propagated as a low-energy plasma disturbance through the interplanetary magnetic field (IMF).

Properties of Forbush Decreases with AMS-02 Daily Proton Flux Data

open access: yesThe Astrophysical Journal, 2023
A Forbush decrease (FD) is a sudden reduction of Galactic Cosmic Rays (GCRs) that is usually caused by intense solar wind transients, such as Interplanetary Coronal Mass Ejections (ICMEs) and Corotating Interaction Regions (CIRs).
