Properties of internal planetary-scale inertio gravity waves in the mesosphere [PDF]
Annales Geophysicae, 2004 At high latitudes in the upper mesosphere, horizontal wind oscillations have been observed with periods around 10h. Waves with such a period are generated in our Numerical Spectral Model (NSM), and they are identified as planetary-scale inertio ...

Arctic amplification: does it impact the polar jet stream?
Tellus: Series A, Dynamic Meteorology and Oceanography, 2016 It has been hypothesised that the Arctic amplification of temperature changes causes a decrease in the northward temperature gradient in the troposphere, thereby enhancing the oscillation of planetary waves leading to extreme weather in mid-latitudes. To

Tropopause-level planetary wave source and its role in two-way troposphere–stratosphere coupling [PDF]
Weather and Climate Dynamics, 2020 Atmospheric planetary waves play a fundamental role in driving stratospheric dynamics, including sudden stratospheric warming (SSW) events. It is well established that the bulk of the planetary wave activity originates near the surface.

A model of mid-latitude E-region plasma convergence inside a planetary wave cyclonic vortex [PDF]
Annales Geophysicae, 2002 Recently, Shalimov et al. (1999) proposed a new mechanism for large-scale accumulation of long-lived metallic ions in the mid-latitude ionosphere driven by planetary waves in the lower thermosphere.

Giant Electrostriction in Halide Perovskites Revisited With Double‐Modulation Interferometry
Advanced Functional Materials, EarlyView.A giant electrostrictive effect in lead halide perovskites had been reported previously. This work uses sensitive interferometry to measure the electromechanical response of various halide perovskite samples. The results reveal no intrinsic electrostrictive compression. Instead, the materials expand primarily under an applied electric field as a result

A balanced state consistent with planetary-scale motion for quasi-geostrophic dynamics
Tellus: Series A, Dynamic Meteorology and Oceanography, 2020 The role of planetary-scale zonally-asymmetric thermal forcing on large-scale atmospheric dynamics is crucial for understanding low-frequency phenomena in the atmosphere. Despite its paramount importance, good theoretical foundation for the understanding

Method for assessing the amplitude modulation of the stationary planetary waves [PDF]
Annales Geophysicae, 2009 This short-communication presents a new method for assessing the amplitude modulation of the stationary planetary waves (SPWs). The suggested procedure allows estimating the contribution of the amplitude modulated SPWs to the field of the zonally ...

Miniature Soft Robot With Magnetically Reprogrammable Surgical Functions
Advanced Materials, EarlyView.Miniature soft robots have great prospects to revolutionize minimally invasive treatments. Here we present a miniature soft robot, which can be reprogrammed to perform five surgical functionalities with six‐degrees‐of‐freedom motions. This soft robot can prospectively make minimally invasive surgery considerably safer and painless, and enable ...

Reponses of middle atmospheric circulation to the 2009 major sudden stratospheric warming
Earth and Planetary Physics, 2020 In this research, the roles of gravity waves and planetary waves in the change to middle atmospheric residual circulation during a sudden stratospheric warming period are differentiated and depicted separately by adopting the downward control principle ...
