Rice Convection Model simulation of the substorm-associated injection of an observed plasma bubble into the inner magnetosphere: 2. Simulation results

摘要: [1] We present results from a Rice Convection Model simulation of the early expansion phase substorm that occurred 22 July 1998. The theoretical basis is idea plasma injected into inner magnetosphere during primarily consists low-content bubble, which made up flux tubes with lower values entropy parameter PV5/3 than their neighbors. As discussed in an accompanying paper, to simulate this event, we carefully tailor model inputs fit Geotail observations bubble at XGSM ≈ −9 RE. We find both potential and induction electric fields play important roles transporting energizing particles event. field associated Birkeland currents flow along east west sides (i.e., current wedge) characterized by localized strengthening westward auroral ionospheric within as well production region enhanced just Equatorward diffuse electron aurora. edge modeled sheet assumes dented-in form similar shape injection boundary proposed many years ago on observational grounds. Flux are pushed earthward ahead onset sharp pressure peak near local midnight geosynchronous orbit, those contribute significantly magnetosphere.
