Convection and Substorms Sufficient?
Dst and aa (~Kp) correlate differently with solar wind [Feynman, 1980].
Storms without SC are recurrent, result from CIRs [Feynman and Guo, 1986].
Storms require sustained SBz, convection in addition to substorms [Gonzalez et al., 1994].
Dipolarization or convection individually insufficient for storm [Fok et al., 1996, 1999].
- Storm = S(substorms) + SBz
However, no correlation of O+ in plasma sheet with AE and substorms [Lennartsson, 1993].
