Statistical Characterization of the Magnetic Field in Space during Magnetic Storms

Atmosphere, 2022
Magnetic storms are an important type of space weather and are usually caused by large streams of charged elementary particles (ions, for example) generated during solar wind production. The occurrence of magnetic storms can pose a threat to the internal
