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.

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).

Relationship between solar activity and myocardial infarctions in Mexico City [PDF]

open access: yesGeofísica Internacional, 2000
Daily incidence of 2290 myocardial infarctions in Mexico City at the National Institute of Cardiology from 1992-1996 shows that the most prominent periodicity in the infarction rate is seven days.

Impact of Forbush Decreases and Geomagnetic Storms on the Atmospheric Ozone Profiles

open access: yesEarth and Space Science, 2023
The sensitivity of atmospheric ozone to geomagnetic storms and reduced cosmic rays' (CRs) intensity (called Forbush decrease [FD]) has been noticed for many years.

The Frequency‐Domain Characterization of Cosmic Ray Intensity Variations Before Forbush Decreases Associated With Geomagnetic Storms

open access: yesSpace Weather, 2022
Nonrecurrent geomagnetic storms caused by Coronal Mass Ejection (CME) can induce serious impacts on space‐ and ground‐based equipment. However, these nonrecurrent geomagnetic storms are hard to predict since CMEs are not periodic.

Forbush decreases and turbulence levels at CME fronts

open access: yes, 2008
We seek to estimate the average level of MHD turbulence near coronal mass ejection (CME) fronts as they propagate from the Sun to the Earth. We examine the cosmic ray data from the GRAPES-3 tracking muon telescope at Ooty, together with the data from ...

Airplane radiation dose decrease during a strong Forbush decrease [PDF]

open access: yesSpace Weather, 2004
An important decrease of onboard air crew exposure level was registered at the Forbush decrease observed during the period of disturbed solar conditions at the end of October 2003. The onboard dosimetry and geophysical data are presented and compared. Comparable decrease is observed for onboard measurements and geographically nearby cosmic ray neutron ...
