  • Gulati, Ishita; Atul, Jyoti Kumar; Kravchenko, Oleg V.; Dlay, Satnam (2022)
    It has been established that polar cap patches are capable of triggering phase scintillation via various convective instabilities such as Gradient Drift, Gravitational Interchange, Current Convective, and Kelvin-Helmholtz ...
  • Shaikh, Zubair I.; Vichare, Geeta (2022)
    Small scale magnetic flux-rope (SSMFR) is ubiquitous in space plasma and contributes to several plasma processes such as; plasma transport, wave activity, acceleration, etc. Here, we have investigated the thermodynamics ...
  • Pooja; Dimri, Ashok Priyadarshan (2024)
    The Indian Himalayan region receives an enormous amount of precipitation due to synoptic weather systems known as Western Disturbances (WDs). WDs are east-ward propagating systems embedded in the Subtropical Westerly ...
  • Esman, Teresa; Halford, Alexa; Pettit, Joshua; Bhanu, Remya; Elliot, Sadie (2024)
    Electromagnetic ion cyclotron (EMIC) waves are waves generated through cyclotron instability and propagate at frequencies near the ion cyclotron frequency. These waves are frequent during geomagnetic storms and significantly ...
  • Arya, Neetasha; Kakad, Amar (2024)
    One of the most important diamagnetic current driven instability transverse to the magnetic field is lower hybrid drift instability (LHDI) which excites lower hybrid drift waves (LHDW). LHDI gives rise to anomalous resistivity ...
  • Shah, Trunali; Bhaskara, Veenadhari; Omura, Yoshiharu; Ojha, Biswajit; Singh, Satyavir; Ebihara, Yusuke (2024)
    The Earth's magnetosphere is a dynamic system subject to various disturbances, among which substorms play a significant role in influencing its impact on the surrounding plasma environment. Close to the substorm onset ...
  • Sharma, Akanksha; Dimri, Ashok Priyadarshan (2024)
    Precipitation has a significant degree of temporal and spatial variability over the Indian region. A small change in precipitation frequency and its distribution may affect agriculture and water resources and can lead to ...
  • Palcu, Dan V.; Braun, David R.; Advokaat, Eldert; Archer, Will S.; Bobe, René; Carvalho, Susana; Forrest, Frances; Hammond, Ashley S.; Kinyanjui, Rahab; Martini, Ana; Mason, Paul; Patterson, David B.; Sier, Mark; Srivastava, Priyeshu; Uno, Kevin; Villaseñor, Amelia; Wynn, Jonathan; Jovane, Luigi; Harris, John W. K.; Koobi Fora Research & Training Program (KFRTP) (2024)
    This study explores the emergence of Oldowan technology in the northeastern part of the Koobi Fora Formation, focusing on a poorly understood spatial and temporal context. It highlights the dynamic interplay between hominins, ...
  • Ahamed, Mohammad Rafijuddin Ali; Sharma, Akanksha; Wani, John Mohd; Dimri, Ashok Priyadarshan (2023)
    In this study, the performance of the output data from the latest high-resolution Coordinated Regional Climate Downscaling Experiment-Coordinated Output for Regional Evaluations (CORDEX-CORE) model simulations is assessed ...
  • Bagiya, Mala S.; Heki, Kosuke (2023)
    The ionospheric manifestations of geohazards of earthquakes and tsunamis are well documented based on the radio sounding of the medium.In particular, Global Navigation Satellite Systems (GNSS) based ionospheric monitoring ...
  • Tacza, José; Bozóki, Tamás; Satori, Gabriella; Bór, József; Neska, Anne; Raita, Tero; Beggan, Ciaran; Atkinson, Mike; Sinha, Ashwini Kumar; Rawat, Rahul (2023)
    Lightning has been declared as a new Essential Climate Variable by the World Meteorological Organization. Schumann resonance is a valuable parameter to monitor the global lightning activity, thus, the Atmospheric Observation ...
  • Pant, P.; Maurya, A. K.; Singh, Rajesh; Veenadhari, B.; Singh, A. K. (2010)
    Lightning generated radio atmospheric that propagates over long distances via multiple reflections through the boundaries of the Earth‐ionosphere waveguide (EIWG), shows sharp dispersion near the cut‐off frequency ∼1.8 kHz ...
  • Aravindakshan, Harikrishnan; Kakad, Amar; Kakad, Bharati (2019)
    Bernstein, Greene, and Kruskal (BGK) have developed the theory for one-dimensional stationary nonlinear electrostatic waves in a collisionless plasma [2]. It is a nonlinear kinetic theory formulated in the one-dimensional ...
  • Bhattacharyya, Archana (2012)
    Effects of space weather on the performance of satellite-based communication/ navigation systems have been studied for several decades. A major concern is the predictability of these effects. Apart from the effects produced ...
  • Singh, Satyavir; Ojha, Biswajit; Lakhina, G. S. (2019)
    Satellite observations in the magnetosphere have shown that Pc 1, 2 waves with frequencies (0.1-5Hz) below the hydrogen gyrofrequency have left-handed to linear polarization and are related to electromagnetic ion cyclotron ...
  • Steffy, S. V.; Ghosh, S. S. (2019)
    One of the natural laboratory for the study of solitary waves is the Earth's magnetosphere. The large gradient in particle properites at the magnetospheric boundary layers initiate the perturbation which leads to the ...
  • Singh, S. V.; Lakhina, G. S.; Bharuthram, R.; Pillay, S. R. (2002)
    The effect of a non-thermal ion velocity distribution is studied on linear and nonlinear dust-acoustic waves in an unmagnetized three component dusty plasma. For the linear theory, electrons are Boltzmann distributed, ions ...
  • Hui, Debrup; Vichare, Geeta (2019)
    Disturbed time prompt penetration electric fields are observed to transmit instantaneously from high to low latitudes and are believed to effect the global ionosphere similarly. However, some new observations claim that ...
  • Pickett, J. S.; Christopher, I. W.; Grison, B.; Grimald, S.; Santolík, O.; Décréau, P. M. E.; Lefebvre, B.; Engebretson, M. J.; Kistler, L. M.; Constantinescu, D.; Chen, L.‐J.; Omura, Y.; Lakhina, G. S.; Gurnett, D. A.; Cornilleau‐Wehrlin, N.; Fazakerley, A. N.; Dandouras, I.; Lucek, E. (2011)
    We present the results of a study of Electrostatic Solitary Waves (ESWs) in which propagation of a series of noncyclical ESWs is observed from one Cluster spacecraft to another over distances as great as tens of km and ...
