PPT-What are Geomagnetic Storms?

Whitney Q Lohmeyer MIT AeroAstro GEM 2013 Gonzalez et al 1994 define geomagnetic storms as An interval of time when a sufficiently intense and longlasting interplanetary convection electric field leads to an intensified ring current strong enough to exceed some key threshold of the quantifying storm time . January 2013 Empower Results TM (1) The analysis of the power system and electric fields calculates a total value ual results may arise from the following factors: i.
