Space weather research in Yakutia

The article reports on the studies of various manifestations of space weather (SW) on Earth, conducted by SHICRA SB RAS at the network of geophysical stations located in Yakutia. It is noted that the Institute researchers study various phenomena occurring in the solar wind and Earth’s magnetosphere such as magnetic clouds, Forbush effects, magnetic storms, substorms and associated subauroral glow, as well as high-latitude impulses in the dayside magnetosphere and sudden phase anomalies in the lower ionosphere. In addition to the data from the network of stations in Yakutia, data from other domestic and foreign stations, as well as direct measurements of the parameters of the interplanetary medium and magnetosphere, carried out on various spacecraft, are used to study these phenomena. The paper also describes physical models of magnetic clouds in the solar wind, high-latitude disturbed ionosphere, and methods for short-term forecasting of SW based on cosmic ray (CR) measurements developed at SHICRA SB RAS.
