The Solar Wind Effect on Cosmic Rays and the Solar Activity
Abstract
The relation of cosmic ray intensity to solar wind velocity is investigated, using neutron monitor data from Kiel and Deep River. The analysis shows that the regression coefficient of the average intensity for a time interval to the corresponding average velocity is negative and that the absolute effect increases monotonously with the interval of averaging, tau, that is, from 0.5% per 100km/s for tau = 1 day to 1.1% per 100km/s for tau = 27 days. For tau 27 days the coefficient becomes almost constant independently of the value of tau. The analysis also shows that this taudependence of the regression coefficiently is varying with the solar activity.
