To the question about perturbations of solar-terrestrial characteristics

TL;DR

This study analyzes data from three solar cycles to explore how solar magnetic field variations relate to interplanetary magnetic fields, solar wind perturbations, and geomagnetic parameters, revealing distinct short-term and long-term response groups.

Contribution

It provides new insights into the relationship between solar magnetic field structures and heliospheric and geomagnetic responses over multiple solar cycles.

Findings

Heliospheric and geomagnetic data split into two response groups.

Distinct short-term and long-term variability patterns identified.

Correlations between photospheric magnetic field and interplanetary parameters established.

Abstract

Data obtained over the last three solar cycles have been analysed to reveal the relationships between the intensity of the photospheric field measured along the line of sight by the WSO group at heliolatitudes from -75 to 75 degrees and the intensity of the interplanetary magnetic field and absolute values of the perturbations of the different characteristics of the solar wind at the Earth orbit, and geomagnetic parameters. provided by the OMNI team. The heliospheric and geomagnetic data are found to be divided into two groups characterized by their response to variability of the solar magnetic field latitudinal structures on short and on long time scales.
