Quiet time F2-layer disturbances: seasonal variations of the occurrence in the daytime sector [PDF]

Annales Geophysicae, 2009
Earlier revealed seasonal/latitudinal variations of the occurrence for positive and negative F2-layer Q-disturbances have been interpreted in the framework of the present-day concept of the thermosphere-ionosphere interaction. The basic process is the

The lower hybrid wave cutoff: A case study in eikonal methods

, 2010
Eikonal, or ray tracing, methods are commonly used to estimate the propagation of radio frequency fields in plasmas. While the information gained from the rays is quite useful, an approximate solution for the fields would also be valuable, e.g., for ...

Relation of daily periods of vlf radiation with X-ray sources

E3S Web of Conferences, 2016
Spectral analysis of electromagnetic noise radiation in the VLF range at three fixed frequencies for the period from 1997 to 2015 have been carried out. Periodograms with diurnal components associated with the periods of the Earth rotation relatively the

Analysis of a global Moreton wave observed on October 28, 2003

, 2009
We study the well pronounced Moreton wave that occurred in as- sociation with the X17.2 are/CME event of October 28, 2003. This Moreton wave is striking for its global propagation and two separate wave centers, which implies that two waves were launched ...
