30TH INTERNATIONAL COSMIC RAY CONFERENCE Effect of high-speed solar wind streams on cosmic ray nucleonic intensity during low amplitude days

چکیده
There are two types of high-speed solar wind streams classified in two categories: coronal hole associated and flare generated streams. These two types of streams are classified in two categories base on magnetic field and solar wind plasma parameters. We studied the dependence of cosmic ray depressions due to high-speed solar wind streams during low amplitude days. Cosmic ray intensity data was subjected to superposed epoch analysis with respect to high-speed solar wind streams start time. The two types of solar wind streams (corotating streams and flare-generated streams) produce significant deviations in cosmic ray intensity during low amplitude anisotropic wave train events. On the onset of both types of streams the cosmic ray intensity reaches to its minimum during low amplitude events and then increases statistically.

Role of high-speed solar wind streams on cosmic ray nucleonic intensity and solar/interplanetary/geomagnetic parameters during low amplitude days
There are two types of high-speed solar wind streams classified in two categories: coronal hole associated and flare generated streams. These two types of streams are classified in two categories based on magnetic field and solar wind plasma parameters. In the present work we have studied the characteristic of cosmic ray nucleonic intensity along with solar/geomagnetic parameters and their inte...
متن کاملSignificance of two types of high-speed solar wind streams in modulating cosmic ray intensity
One of the most dynamical interplanetary phenomena of solar terrestrial physics is definitely the passage of solar wind streams near the Earth environment. In this work, we have identified the two types of high-speed solar wind streams using the spacecraft data during high amplitude days. The behaviour of high-speed solar wind streams during high amplitude anisotropic wave trains is investigate...
متن کاملCosmic ray anisotropy along with interplanetary transients
Abstract The present work deals with the study of first three harmonics of low amplitude anisotropic wave trains of cosmic ray intensity over the period 1991-1994 for Deep River neutron monitoring station. It is observed that the diurnal time of maximum remains in the co-rotational direction; whereas, the time of maximum for both diurnal and semi-diurnal anisotropy has significantly shifted tow...

Abstract This work deals with the time evolution of the three harmonics of the unusual diurnal variation of cosmic ray intensity during high amplitude anisotropic wave trains. The relation of these harmonics to interplanetary parameters such as Dst-index, Ap-index, solar wind speed and interplanetary magnetic field (Bz) is investigated in order to found the possible origin of these anisotropic ...
متن کاملObservations of galactic cosmic rays and the anomalous helium during Ulysses passage from the south to the north solar pole
We compare observations of the modulated intensities and spectra of galactic cosmic ray nuclei and anomalous heliumabove 30MeV/nmeasured by theCOsmic andSolar Particle INvestigations (COSPIN) High Energy Telescope (HET) on Ulysses with similar observations from the IMP-8 earthorbiting satellite between September 1994 and August 1995. During this interval Ulysses made a rapid scan of solar latit...
