A turbulence in the F region of the ionosphere, usually due to a sudden burst of radiation from the sun; it is accompanied by a decrease in the density of ionization and an increase in the virtual height of the region.

The disappearance of the crests corresponds to the negative ionospheric storm observed in the [DELTA]VTEC maps of Figure 5.
Finally, a localized TEC decrement (or negative ionospheric storm) was also identified.
This period coincided with a severe ionospheric storm caused by a "solar bullet" of charged particles emitted by the sun.

This is connected with creation of global model of ionospheric storms and providing stable navigation in polar region.
There are no grooves, no words and no obvious framework: just an ominous, dynamic texture with occasional ionospheric storms or a muffled scream.
The F1 layer exists only during the daytime and is more noticeable during the summer months, during periods of high sunspot activity and during ionospheric storms. When utilizing the F1 layer for propagation of radio waves, it is necessary to increase frequency to extend the broadcast range.
