The State Department warning said that embassy personnel had seen "an increase in the number of irregularities appearing in orphan petitions and visa applications," and "significant increases in the number of abandoned children" in two provinces, including Thai Nguyen, where the three contested babies were adopted.
In the stagnation and base regions, the surface irregularities appeared to dominate.
Ionospheric irregularities appear as scattered echoes in high-frequency (HF) band ionograms that are known as spread-F events.
Decameter-scale irregularities appear as diffuse echoes in the ionograms (e.g. Abdu et al., 1983), which is related to the name, Equatorial Spread-F (ESF).
Therefore, the linear theory predicts unstable conditions only below the F peak altitude, but density irregularities appear throughout the F region.
Here we used all ascending passes corresponded to the evening sector (~20.3 LT), when in the post-sunset period the equatorial irregularities appear normally.
We have already shown how small-scale irregularities appear along the west wall (Tsunoda 1981; Tsunoda et al. 2011) during the growth phase ('Growth phase: amplification of upwellings' section).
For this spots were weighted based on feature flagging in Genepix: weak signal and feature irregularity appeared to be the main source of discrepancy therefore features were flagged to avoid these spots.
Irregularities may appear in the fibula, in some adolescents [4].
Irregularities can appear in a specific region or can be created over wide areas by global-scale processes such as magnetic storms.
