abstract = "Using the global ionospheric map of total electron content in
2002-2009, this paper investigates anomalous, midlatitude electron
density enhancement (MEDE) bounded by a tropical electron density
trough and the usual midlatitude electron density trough at all
times (24h) of the day for the first time. The diurnal, seasonal,
and longitudinal variations in the occurrence and strength of MEDE
are studied at solar maximum (2002) and long deep solar minimum
(2009), and latitude-longitude dependence is examined using the
data in 2002-2009. The results show that the MEDE occurs at all
times of the day though pronounced at night (2200-0400LT), and in
some cases the daytime occurrence could be more frequent than the
corresponding nighttime occurrence. The strength maximizes at
around 0400LT and is weak during daytime. Both the occurrence and
strength are, in general, predominant in winter at low solar
activity and exhibit significant longitudinal dependence. The ExB
drift, strength, and direction of neutral wind and
ionosphere-plasmasphere plasma flow and their day-to-day
variations are suggested to account for the existence of MEDE at
all times of the day.",
