WebAug 15, 2024 · In addition to substorms, the magnetosphere can respond to solar wind forcing by entering into steady magnetospheric convection (SMC) periods (e.g., Sergeev et al., 1996; Kissinger et al., 2012 ). Hence, a type B process would imply weaker substorms and/or less frequent SMC events for opposite signs of IMF B y and Ψ.
