Some ionospheric storm effects at an antarctic station
(Elsevier, 2016-03)
In this paper, the ionospheric response of a high latitude station to some intense geomagnetic storms occurred in 2000 and 2001 is analyzed. For that, data of the critical frequency of the F2-layer foF2 and the virtual ...
Validation of the STORM model in IRI-2001 at a high latitude station
(Elsevier, 2009-09)
The International Reference Ionosphere IRI-2001 model contains geomagnetic activity dependence based on an empirical storm time ionospheric correction (STORM model). An extensive validation of the STORM model for the middle ...
Longitudinal variations of positive dayside ionospheric storms related to recurrent geomagnetic storms
(American Geophysical Union, 2013-10-31)
We have performed an analysis of case events and statistics of positive ionospheric storms in the dayside region of the equatorial ionization anomaly during recurrent geomagnetic storms (RGSs), which dominate in geomagnetic ...
Solar Cycle and Seasonal Distribution of Geomagnetic Storms with Sudden Commencement
(Canadian Center of Science and Education, 2014-02)
In this brief paper the seasonal and solar cycle distribution of storms with sudden commencement is presented. A correlation between the number of geomagnetic storms by month and monthly sunspot numbers is observed. Also, ...
Some ionospheric storm effects at equatorial and low latitudes
(Elsevier, 2014-04)
In this paper, the response of the equatorial and low latitude ionosphere to three intense geomagnetic storms occurred in 2002 and 2003 is reported. For that, critical frequency of F2-layer foF2 and the peak height hmF2 ...
Relative effects of electric field and neutral wind on positive ionospheric storms
(SpringerOpen, 2009-05-14)
The paper studies the relative importance of penetrating eastward electric field (PEEF) and direct effects of equatorward neutral wind in leading to positive ionospheric storms at low-mid latitudes using observations and ...
Some ionospheric storm effects at equatorial and low latitudes
(Elsevier, 2014-03-04)
In this paper, the response of the equatorial and low latitude ionosphere to three intense geomagnetic storms occurred in 2002 and 2003 is reported. For that, critical frequency of F2-layer foF2 and the peak height hmF2 ...
Disturbances at F2-region heights of equatorial anomaly during geomagnetic storms
(Elsevier, 2003-12)
Neutral gas composition and ionospheric measurements taken by the Dynamic Explorer 2 satellite at F2-region heights during two geomagnetic storms are used to analyze the role of some possible physical mechanisms responsible ...
Peculiar features of the low‐latitude and midlatitude ionospheric response to the St. Patrick's Day geomagnetic storm of 17 March 2015
(American Geophysical Union, 2016-07-25)
The current study aims at investigating and identifying the ionospheric effects of the geomagnetic storm that occurred during 17–19 March 2015. Incidentally, with SYM‐H hitting a minimum of −232 nT, this was the strongest ...
Moderate geomagnetic storms and their ionospheric effects at middle and low latitudes
(Elsevier, 2011-08)
This paper reports the global response of the mid high and low latitude ionosphere in four longitudinal sectors to two moderate geomagnetic storms that occurred during 2007 (the more intense storms occurred that year). The ...
