Abstract
The medium-scale traveling ionospheric disturbances (MSTIDs) can be excited by many sources. Among those magnetic reconnection has been proposed as a potential driver for dayside MSTIDs, but direct evidence has been limited. Using ground-based radar data from the Super Dual Auroral Radar Network on 14 December 2012, we observed quasi-periodic multiple MSTIDs propagating from auroral latitudes to mid latitudes near magnetic local noon, which showed one-to-one correspondences to intermittent lobe reconnections with periodicities of about 20–30 min. Simultaneous EISCAT Svalbard incoherent scatter radar data revealed enhanced electric field and Joule heating within the cusp region following each lobe reconnection. These multi-instrument observations strongly suggest lobe reconnection as a possible driver for the dayside MSTID.
期刊介绍：
Geophysical Research Letters (GRL) publishes high-impact, innovative, and timely research on major scientific advances in all the major geoscience disciplines. Papers are communications-length articles and should have broad and immediate implications in their discipline or across the geosciences. GRLmaintains the fastest turn-around of all high-impact publications in the geosciences and works closely with authors to ensure broad visibility of top papers.
