Webb20 mars 2024 · Recurrent storms are caused by features on the Sun called coronal holes that live for several months and generate corotating interaction regions (disturbances in the solar wind where the fast solar wind from the coronal holes catches up with the slow solar wind) that repeat on the 27-day solar rotation period. Webb9 juni 2012 · A geomagnetic storm is a temporary disturbance of the Earth magnetosphere caused by a solar wind shock wave associated with CMEs, coronal holes or solar flares. Many researchers [ 18 – 20] have suggested the CMEs are a possible cause of geomagnetic storms. CMEs are a relatively new phenomenon compared to the solar …
