Rainfalls during great Forbush decreases

Il Nuovo Cimento C, 1995
The changes of rainfall values during great Forbush decreases recorded by the low-latitudinal neutron monitor of Huancayo (47 events from 1956 through 1992) were examined. The data on precipitations were taken from the State of Sao Paulo and from the Amazonian region, Brazil.

Forbush decreases and $

2019
Non-recurrent short term variations of the galactic cosmic-ray (GCR) flux above 70 MeV n$^{-1}$ were observed between 2016 February 18 and 2017 July 3 aboard the European Space Agency LISA Pathfinder (LPF) mission orbiting around the Lagrange point L1 at 1.5$\times$10$^6$ km from Earth.

Rigidity Dependence of Forbush Decreases

Publications of the Astronomical Society of Australia, 1992
AbstractIna recent paper, Lockwood et al. (1991) have used IMP spacecraft and Neutron Monitor data to consider the rigidity dependence of three large Forbush Decreases over the energy range 50 MeV to 30 GeV. Some of their conclusions are extrapolated to higher energies.

Diurnal variation and Forbush decrease

Il Nuovo Cimento, 1961
In this work we discuss the depressions often preceding the most important Forbush decreases by less than 24 h, and certain features of a Forbush decrease such as the rarity of onsets during morning hours, the greater amplitude when they happen during the evening as well as the small increases that sometimes happen during the main decrease.

Interplanetary disturbances during Forbush decreases

Il Nuovo Cimento C, 1984
The interplanetary perturbations associated with Forbush decreases (FDs) during the period 1965–1974 are studied. The systematic appearance of the results obtained confirms once again that type-IV solar flares are the origin of these perturbations. The front perturbation is a wide (∼100° in longitude) driven shock followed by a magnetic blob and a high-

An Anomalous Forbush Decrease

Publications of the Astronomical Society of Australia, 1968
Ground level detectors observed several major changes in the primary cosmic-ray flux during November 4960. Large increases, of solar origin, occurred on November 12 and 15, and a smaller one on November 20. The galactic flux in the region of the Earth was severely reduced by a Forbush decrease on November 12, and remained notably depressed until ...

Observing Forbush decreases in cloud atShetland

Journal of Atmospheric and Solar-Terrestrial Physics, 2010
Abstract Meteorological measurements from Lerwick Observatory, Shetland (60°09′N, 1°08′W), are compared with short-term changes in Climax neutron counter cosmic ray measurements. For transient neutron count reductions of 10–12%, broken cloud becomes at least 10% more frequent on the neutron minimum day, above expectations from sampling. This suggests

Forbush decreases and interplanetary disturbances

Il Nuovo Cimento B, 1973
The correlation between perturbations of the interplanetary medium and Forbush decrease events is studied by using interplanetary-magnetic-field and cosmic-ray data for the period March to November 1968, with the purpose of investigating the particular mechanism responsible for this type of modulation of the cosmic-ray intensity.

Forbush decreases and geomagnetic storms

Geomagnetizm i aèronomiâ
Forbush decreases in galactic cosmic rays (according to data from a network of neutron monitors) and accompanying geomagnetic disturbances over a long period from 1957 to 2022 have been identified and studied. Statistical relationships between various parameters of cosmic ray flux and geomagnetic activity indices are analyzed.

Flares, Forbush decreases, and geomagnetic storms

Journal of Geophysical Research, 1969
Geomagnetic storms and Forbush decreases accounted for by interplanetary solar corpuscular streams effects described by interplanetary magnetic field structure, noting independence of ...
