A balanced state consistent with planetary-scale motion for quasi-geostrophic dynamics
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]
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 ...

This review systematically summarizes recent advances in porosity engineering of MXenes, with a focused discussion on their structure‐governed energy storage properties. A critical analysis of structure–property relationships is presented across alkali‐ion batteries, multivalent‐ion batteries, and supercapacitors.

Reponses of middle atmospheric circulation to the 2009 major sudden stratospheric warming
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 ...

Radiative effects of ozone waves on the Northern Hemisphere polar vortex and its modulation by the QBO [PDF]
The radiative effects induced by the zonally asymmetric part of the ozone field have been shown to significantly change the temperature of the NH winter polar cap, and correspondingly the strength of the polar vortex.

Constraints on wave drag parameterization schemes for simulating the quasi-biennial oscillation. Part II: combined effects of gravity waves and equatorial planetary waves [PDF]
This study examines the effect of combining equatorial planetary wave drag and gravity wave drag in a one-dimensional zonal mean model of the quasi-biennial oscillation (QBO). Several different combinations of planetary wave and gravity wave drag schemes

A four‐year investigation is being made in the Pacific Ocean for unseen and elusive ocean waves that are thought to be about 1000 miles in length and take two weeks to a month to complete one cycle. Planetary waves are believed to be caused by the gravitational attraction of the sun and moon on the earth.

A wet ball‐milling method is presented to synthesize iron magnetic nanoparticles and evaluate their magnetic hyperthermia performance. Optimized particles (∼270 nm, Ms ∼114 emu/g) achieve ∼50°C heating under clinically safe alternating magnetic fields, while pulsed‐field operation enables controlled temperature regulation (∼30°C).

On the new modes of planetary-scale electromagnetic waves in the ionosphere [PDF]
Using an analogy method the frequencies of new modes of the electromagnetic planetary-scale waves (with a wavelength of 103 km or more), having a weather forming nature, are found at different ionospheric altitudes.
