In this study, a numerical examination of the significance of rotation and changeable gravitational field on the start of nanofluid convective movement in an anisotropic porous medium layer is shown. A model that accounts for the impact of Brownian diffusion and thermophoresis is used for nanofluid, while Darcy’s law is taken for the porous medium. The porous layer is subjected to uniform rotat...

Abstract Gravity waves (GWs) and their associated multi‐scale dynamics are known to play fundamental roles in energy momentum transport deposition processes throughout the atmosphere. We describe an initial machine learning model—the Compressible Atmosphere Model Network (CAM‐Net). CAM‐Net is trained on high‐resolution simulations by state‐of‐the‐art model Complex Geometry (CGCAM). Two applicat...

Photonics enables to develop simple lab experiments that mimic water rogue wave generation phenomena, as well as relativistic gravitational effects such as event horizons, gravitational lensing and Hawking radiation. The basis for analog gravity experiments is light propagation through an effective moving medium obtained via the nonlinear response of the material. So far, analogue gravity kinem...

Some results are presented of the Earths microseismic background. It is assumed that background peaks should correspond to the resonance gravity-wave exchange in the system of two gravity-connected bodies. The microseismic spectrum is compared with the distribution of gravity potential of the nearest stars. A close peak-to-peak correspondence is found. This correspondence and resonance conditio...

Recently, the possibility has emerged of an early detection of astrophysical gravity waves. In certain astronomical configurations, and through a new light-deflection effect, gravity waves can cause apparent shifts in stellar angular positions as large as 10arcsec. In these same configurations, the magnitude of the gravity-wave-induced time-delay effect can exceed 10. Both these figures lie jus...

Atmospheric gravity waves play fundamental roles in a broad-range of dynamical processes extending throughout the Earth’s neutral atmosphere and ionosphere. In this paper, we present a modified form for the acoustic-gravity wave equation and its dispersion relationships for a compressible and non-stationary atmosphere in hydrostatic balance. Importantly, the solutions have been achieved without...

One of the primary objectives of MAP was to understand the generation of gravity waves from high complex terrain, and the breakdown of those waves. Several weak to moderate gravity wave events during the MAP field phase were studied with a remarkable fleet of research aircraft equipped with GPS navigation, gust probes, dropsondes and downlooking LIDAR. These data sets have been carefully analyz...
