The ionospheric footprint of antiparallel merging regions on the dayside magnetopause

The antiparallel merging hypothesis states that reconnection takes place on the dayside magnetopause where the solar and geomagnetic ®elds are oppositely directed. With this criterion, we have mapped the predicted merging regions to the ionosphere using the Tsyganenko 96 magnetic ®eld model, distinguishing between regions of sub-Alfve nic and super-Alfve… CONTINUE READING
