Geomagnetism and Aeronomy Aims and scope Submit manuscript

Abstract

The station-ring method makes it possible to isolate and study the specific angular distributions of cosmic-ray variations that are poorly described by the sum of the first spherical harmonics. Examples of the use of the station-ring method are given and described in detail. The application of the method to study precursors of Forbush effects and the behavior of cosmic rays inside the perturbations of the solar wind is shown.
