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.

Long-term Statistical Analysis of the Simultaneity of Forbush Decrease Events at Middle Latitudes [PDF]

open access: yesJournal of Astronomy and Space Sciences, 2015
Forbush Decreases (FD) are transient, sudden reductions of cosmic ray (CR) intensity lasting a few days, to a week. Such events are observed globally using ground neutron monitors (NMs).

Magnetic Cloud and Its Interplanetary Shock Sheath as a Modulator of the Cosmic Ray Intensity [PDF]

open access: yesJournal of Astronomy and Space Sciences, 2008
Forbush Decreases (FDs) are representative events of abrupt decrease in galactic cosmic ray intensity. They are known to be strongly associated with solar wind events such as interplanetary shock (IP shock) and magnetic cloud (MC).

The amplitude and phase distributions of cosmic ray variation at different conditions of Forbush decrease

open access: yesResults in Physics, 2022
The Forbush effect is one of the striking examples of irregular variations in the cosmic ray (CR) flux. It is a heliospheric phenomenon that includes a decrease and a recovery of the CR intensity and small changes in the CR density and anisotropy before ...

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.

Forbush-storm classification of the events as a device for the solar wind diagnostics [PDF]

open access: yesE3S Web of Conferences, 2020
The geoeffectiveness of the solar wind is usually determined on Earth by such phenomena in the geomagnetic field as storms and substorms. The second, no less significant effect is a sharp decrease in the intensity of galactic cosmic rays (GCR) Forbush ...

A new model describing Forbush Decreases at Mars: combining the heliospheric modulation and the atmospheric influence

open access: yesEarth and Planetary Physics, 2020
Forbush decreases are depressions in the galactic cosmic rays (GCRs) that are caused primarily by modulations of interplanetary coronal mass ejections (ICMEs) but also occasionally by stream/corotating interaction regions (SIRs/CIRs).

Implications of Solar Wind Disturbances on Forbush Decrease [PDF]

open access: yesPhysics Access
This study investigated the role of solar wind disturbances on variations in cosmic ray intensity. To conduct the study, use was made of the data on cosmic rays from the SOPO, CLMX, and MOSC neutron stations, as well as solar wind speed data from 2000 ...

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.
