The storm is mainly characterized by a decrease in the horizontal component H of the geomagnetic field, which encompasses the entire planet during a geomagnetic storm. They argue that a storm results from the extended interaction of the solar wind/magnetosphere when a strong convection electric field is generated, which is able to perturb the ring current above some threshold level, triggering the event. The authors present a review of geomagnetic storm research. The US government's space weather tracking body has warned the public about the possibility of a of geomagnetic storm, which is different from a solar storm. The magnetosphere is affected by the solar wind flow, and in the normal state, the pressure of the magnetic shell of our planet . After a brief review of magnetospheric and interplanetary phenomena for intervals with enhanced solar wind-magnetosphere interaction, an attempt is made to define a geomagnetic storm as an interval of time when a sufficiently intense and long-lasting interplanetary convection electric field leads, through a substantial energization in the magnetosphere-ionosphere system, to an intensified ring . Magnetometers measure the strength of Earth's magnetic field to determine the K-index, which is tied to a specific station.
