A numerical model of the ionospheric signatures of time-varying magnetic reconnection: III. Quasi-instantaneous convection responses in the Cowley-Lockwood paradigm

Using a numerical implementation of the Cowley and Lockwood (1992) model of flow excitation in the magnetosphere–ionosphere (MI) system, we show that both an expanding (on a _12-min timescale) and a quasiinstantaneous response in ionospheric convection to the onset of magnetopause reconnection can be accommodated by the Cowley–Lockwood conceptual framework. This model has a key feature of time dependence, necessarily considering the history of the coupled MI system. We show that a residual flow, driven by prior magnetopause reconnection, can produce a quasi-instantaneous global ionospheric convection response; perturbations from an equilibrium state may also be present from tail reconnection, which will superpose constructively to give a similar effect. On the other hand, when the MI system is relatively free of pre-existing flow, we can most clearly see the expanding nature of the response. As the open-closed field line boundary will frequently be in motion from such prior reconnection (both at the dayside magnetopause and in the cross-tail current sheet), it is expected that there will usually be some level of combined response to dayside reconnection.

Mrs. J. Palmer Lockwood Journal - Accession 34 - M10 (20)

The Mrs. J. Palmer Lockwood Journal consists of a 76 page journal kept by Mrs. J. Palmer (Leize) Lockwood concerning how the poem Carolina by Henry Timrod became the South Carolina state song. There is also a description of how Mrs. Lockwood worked to popularize the song, three copies of Timrod’s poem, and a copy of a poem titled “Carolina” by Mary Frances Wickliffe, Winthrop faculty member from 1895 to 1919.
