magnetic reconnection
Quick Summary
Magnetic reconnection is a fundamental process in atmospheric science where the Sun's magnetic field, carried by the solar wind, links with Earth's magnetic field. This interaction occurs within Earth's magnetosphere, a region shaped by the solar wind.
When these magnetic fields connect, energy is released through dynamic reconfigurations of the magnetosphere, known as geomagnetic substorms. This process often leads to energetic particles precipitating into the ionosphere, causing visible auroral displays. Magnetic reconnection also generates a magnetospheric electric field and drives magnetospheric convection, influencing phenomena like magnetic storms and the Van Allen radiation belts.12

…magnetosphere through the process of magnetic reconnection—the same process responsible for the formation of CMEs. If the IMF or the magnetic field inside a CME has a strong southward component, it can efficiently couple with the northward-pointing geomagnetic field, releasing much energy, transferring the mass and momentum of the solar…
