Gravitational instability in partially ionized plasmas: A two-fluid approach
A. P. Misra, V. Krishan
We propose a new two-fluid model for a partially ionized magnetoplasma under gravity, in which electrons and neutrals are treated as a single fluid, while singly charged positive i…

Thermoacoustic internal gravity wave turbulence in the Earth's lower atmosphere
S. Das Adhikary, A. P. Misra
We propose, for the first time, a two-dimensional model for the nonlinear coupling of internal gravity and thermal waves in the presence of temperature-dependent density inhomogene…

Rayleigh-Bénard convective motion of stratified fluids in the Earth's troposphere
A. P. Misra, T. D. Kaladze, D. T. Kaladze +1
Recently, Kaladze and Misra [Phys. Scr. 99 (2024) 085013] showed that the tropospheric stratified fluid flows may be unstable by the effects of the negative temperature gradient an…
