Influence of geomagnetic storms on the mid latitude D and F2 regions
Naidu, Pyla; Madhavilatha, Tirumalaraju; Devi, Malladi; Published by: Annals of Geophysics Published on: |
order to examine if the variations in the TEC were caused by thermospheric composition changes in the southern high-latitude regions, we present O/N 2 maps obtained from the GUVI Shreedevi, PR; Choudhary, RK; Thampi, Smitha; Yadav, Sneha; Pant, TK; Yu, Yiqun; McGranaghan, Ryan; Thomas, Evan; Bhardwaj, Anil; Sinha, AK; Published by: Space Weather Published on: YEAR: 2020   DOI: 10.1029/2019SW002383 |

Morphological features of the quiet/disturbed time variations in the Total Electron Content (TEC) at the polar cusp station Bharati (76.69\textdegreeS MLAT) during a period of 5 years starting from February 2013 to December 2017 has been studied using GPS TEC measurements. The TEC at Bharati follows a diurnal pattern with its peak appearing close to local noon/magnetic noon during the summer/winter months. A nighttime enhancement in the TEC is seen around the magnetic midnight during winter. The plasma density at Bharati ...

Influence of Geomagnetic Storms on Ionospheric F2-Layer at Low and Mid Latitudes in 300 E Meridian
Naidu, Peddi; Latha, Madhavi; Devi, Indira; Published by: Geomagnetism and Aeronomy Published on: |
The paper presents atmospheric coupling physics through identifying a few significant features imprinted on the ionosphere by certain unique seismic environments when a number of successive cluster of earthquakes ranging from 7.1 to 8.2 magnitudes occurred within about two weeks period, over the East-West Pacific zone covering Devi, M; Barbara, AK; Patgiri, S; Depueva, A; Oyama, K; , Depuev; Ruzhin, Yu; , others; Published by: Geomagnetism and Aeronomy Published on: YEAR: 2019   DOI: 10.1134/S0016793219080036 |

We show evidence of a positive ionospheric storm occurring simultaneously at the equatorial, low-latitude and mid-latitude ionospheric regions in the Indian sector in response to an intense geomagnetic storm on 17 March 2013. The storm had its onset time coinciding with the local noon. An on-site digisonde at Trivandrum (dip equator) recorded a sharp decrease in the height of F\ region peak in the afternoon, which is a signature of westward electric field associated with a counter electrojet (CEJ). Coupled w ... Published by: Journal of Geophysical Research: Space Physics Published on: 10/2017 YEAR: 2017   DOI: 10.1002/2017JA023980 |

A case of the westward disturbance dynamo (DD) electric field, influencing the daytime equatorial and low-latitude ionosphere, during a geomagnetic storm that occurred on 28\textendash29 June 2013 is presented. The GPS total electron content (TEC) observations from a network of stations in the Indian equatorial, low and middle latitude regions along with the radio beacon TEC, ionosonde, and magnetic field observations are used to study the storm time behavior of the ionosphere. Negative ionospheric storm effects were seen ...

The relative contributions of the composition disturbances and the disturbance electric fields in the redistribution of ionospheric plasma is investigated in detail by taking the case of a long-duration positive ionospheric storm that occurred during 18\textendash21 February 2014. GPS total electron content (TEC) data from the Indian Antarctic station, Bharti (69.4\textdegreeS, 76.2\textdegreeE geographic), the northern midlatitude station Hanle (32.8\textdegreeN, 78.9\textdegreeE geographic), northern low-latitude statio ...
