Forbush-storm classification of the events as a device for the solar wind diagnostics

The geoeffectiveness of the solar wind is usually determined on Earth by such phenomena in the geomagnetic field as storms and substorms. The second, no less significant effect is a sharp decrease in the intensity of galactic cosmic rays (GCR) Forbush effects. A joint examination of these effects in the geomagnetic field and in the GCR makes it possible to obtain additional diagnostic features, since they carry different information. The behavior of the geomagnetic field reflects changes in the magnetosphere, while the GCR intensity depends on the spatial configuration of the magnetic field in the heliosphere. To carry out such work, it is proposed to use the Forbush-Storm classification — a catalog of geophysical events in the geomagnetic field and cosmic rays. The catalog shows the dates and time of the beginning of the events of a decrease in the Dst geomagnetic field index and in GCR intensity from 1996 to 2017, for 2 cycles of solar activity. It is shown that these two types of terrestrial manifestations of interplanetary disturbances can occur simultaneously or separately.
