Gravity wave activities in Tibet observed by COSMIC GPS radio occultation

Geodesy and Geodynamics, 2018
The Gravity waves activities in the Tibetan Plateau are very complex with different effects and natures that are not clear due to the lack of high resolution data from space and also from ground. In this paper, using COSMICGPS radio occultation data from

Interplanetary frontiers: terraforming from an invasion science perspective

Oikos, EarlyView.
The pursuit of a multi‐planetary existence represents one of humanity's greatest frontiers. If applied justly, it offers an opportunity to extend its civilization's lifespan amid escalating sustainability crises on Earth. One approach increasingly gaining traction is terraforming, a hitherto theoretical ecological and evolutionary experiment revolving ...

Time–space fractional (2+1) $(2+1)$ dimensional nonlinear Schrödinger equation for envelope gravity waves in baroclinic atmosphere and conservation laws as well as exact solutions

Advances in Difference Equations, 2018
In this article, nonlinear propagation of envelope gravity waves is studied in baroclinic atmosphere. The classical (2+1) $(2+1)$ dimensional nonlinear Schrödinger (NLS) equation can be derived by using the multiple-scale, perturbation method.

Experimental Investigation of Moisture Movement During Freeze–Thaw Cycles and Its Effect on Physical Rock Weathering in Low‐Porosity Alpine Limestone

Permafrost and Periglacial Processes, EarlyView.
ABSTRACT The progressive weakening of alpine rockwalls through subcritical cracking, driven by repeated low‐magnitude stress processes, plays a key role in alpine rock weathering. Laboratory studies using acoustic emission (AE) monitoring have shown that thermal stresses from freeze–thaw cycling induce crack propagation, with recent work highlighting ...
