Scientific paper
Midlatitude irregularities in F-region electron density have been previously observed in-situ by the Atmosphere Explorer-E satellite [Hanson and Johnson, 1992]. These authors noted the similarity of the irregularities to equatorial spread-F, which is commonly observed at much lower latitudes (within 20 degrees of the magnetic equator). They coined the term midlatitude disturbances (MLDs), and postulated that the irregularities resulted from the Perkins instability in a region where the east-west velocities of the ions differs from that of the neutrals. We present ionosonde observations of range spread-F made over Wallops Island, VA that may show signatures of similar MLD events. The data show evidence of an apparent correlation between the occurrence of the irregularities and the passage of hurricane Dennis over the magnetic meridian of Wallops Island. Based on this evidence, we examine the possibility that the Perkins instability and/or MLD events can be triggered by gravity waves spawned by the hurricane. Reference: Hanson, W.B., and F.S.
