Stratosphere–Troposphere Coupling During Cold Air Outbreaks in the Eastern United States
Abstract Cold air outbreaks (CAOs) are extreme weather events characterized by the equatorward displacement of polar air. This study investigates CAOs occurring along the East Coast of the US and establishes that approximately 16% are driven by stratosphere‐troposphere coupling through wave dynamics.

Abstract Atmospheric rivers (ARs) influence weather and climate along the North American west coast, yet their effects on Pacific Northwest (PNW) surface temperatures remain unclear across seasons and synoptic configurations. Motivated by the 2021 PNW heatwave—which was preceded by a poleward‐tracking AR—we analyze how ARs modulate daily maximum ...

Slow magnetic Rossby waves in the Earth's core
The westward drift component of the secular variation is likely to be a signal of waves riding on a background mean flow. By separating the wave and mean flow contributions, we can infer the strength of the “hidden” azimuthal part of the magnetic field ...

Abstract Anthropogenic warming is expected to substantially modify the hydroclimate of South America, a region in which low‐level jets (LLJs) and mesoscale convective systems (MCSs) are key components of moisture transport and precipitation. However, the responses of these systems to future climate change, including the relative roles of thermodynamic ...

Detecting an Ocean Inside Callisto With Geodetic Measurements From Europa Clipper and Juice
Abstract Determining whether Callisto hosts a subsurface ocean, and the implications for material and energy transport through its hydrosphere, is of high interest to NASA's Europa Clipper and ESA's Juice missions. A recent reanalysis of Galileo magnetometer data strengthens the ocean hypothesis, but definitive confirmation awaits new measurements.

In this paper, the theoretical model of Rossby waves in two-layer fluids is studied. A single quasi-geostrophic vortex equation is used to derive various models of Rossby waves in a one-layer fluid in previous research.

The linearized shallow water equations, when applied to a rotating annulus of homogeneous fluid with a free surface, and depth proportional to radius squared, have solutions expressible in elementary functions. The low frequency “second-class” part of the spectrum obeys an equation similar to Haurwitz's formula for Rossby waves on the earth.

Abstract Despite global warming, China continues to experience record‐breaking cold extremes. However, the extent to which internal atmospheric circulation variability offsets anthropogenic warming effects on cold extremes remains poorly quantified. Here, a nonstationary GEV is used to quantify the relative influences of anthropogenic warming and the ...

Doppler and Non-Doppler Shifts in Dispersion Relations for Rossby Waves and Galilean Invariance
The purpose of this work is to draw the reader's attention to a paradoxical fact – the existence of two different dispersion relations for linear Rossby waves: with Doppler and nonDoppler shifts.
