In addition, we observe the equinoctial irregularity in EIA crest with respect to annual, semiannual and equinox.
A question that remains, is why do we observe small-scale irregularities (< few km) along the west wall of an upwelling, at a time when EPBs appear to be suppressed?
We observed strong ionospheric irregularities in the topside ionosphere during the storm's main phase that were associated with storm-enhanced density (SED) formation at mid-latitudes and further evolution of the SED plume to the polar tongue of ionization (TOI).
However, in some of the cases, immediately after the onset of the storm, we observed the enhancement of irregularities.
Longitudinal distributions of post-midnight equatorial ionospheric irregularity occurrences observed by ROCSAT-1 (1st satellite of the Republic of China) during moderate to high solar activity years in two solstices are studied with respect to the vertical drift velocity and density variations.
The global seasonal/longitudinal (s/l) distributions of density irregularity occurrences observed by ROCSAT-1 from 1999 to 2004 are plotted in the upper panels of each season - March equinox, June solstice, September equinox, and December solstice.
The cost of irregularity observed for first position irregular word is likely to result from initiating articulation.
We found major differences between the shapes of irregularities' structures observed by these techniques.
We should also emphasize that the intense ionospheric irregularities were observed over Southern Europe at ~25°N 40°N geographic latitude during the main phase of the storm at 20-04 UT (Figs. 4; Additional file 2: S2, Additional file 3: S3).
The dash-dotted red vertical lines in the left plots mark the period when the F-region irregularity growth was observed.
It is interesting to note that most investigators, when considering the pathology of this disease, fail to evaluate the glenohumeral joint in its entirety but rather restrict themselves to some local irregularity observed in the labrum glenoidale, fibrous capsule or head of the humerus.
