Existence of small-scale Rossby waves points to low convective velocity amplitudes in the Sun
Inertial waves occur naturally in rotating fluids such as the Sun and the Earth's atmosphere. Rossby waves in the Sun have the potential to shed fresh light on interior turbulence and convection that prior seismic methods, reliant on sound waves, have ...

Large Eddy Simulations of the Atmospheric Boundary Layer Over Satellite‐Sensed Sea Ice Maps
Abstract Surface heterogeneity in the marginal ice zone (MIZ) causes multiscale secondary atmospheric circulations that are challenging to model or observe. The absence or inadequate representation of these circulations in ocean‐atmosphere exchange schemes in climate models is partially responsible for the underestimation of Arctic sea ice loss ...

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.

The interaction of free Rossby waves with semi-transparent equatorial waveguide – wave-mean flow interaction [PDF]
Nonlinear interactions of the barotropic Rossby waves propagating across the equator with trapped baroclinic Rossby or Yanai modes and mean zonal flow are studied within the two-layer model of the atmosphere, or the ocean. It is shown that the equatorial

Abstract Mesoscale eddies are crucial for global heat and tracer transport, yet the mechanisms underlying their meridional movement remain unclear. Here, we combine satellite observations, idealized numerical experiments, and theoretical modeling to investigate these mechanisms. We demonstrate that the meridional eddy movement is strongly linked to the

Enhanced Interdecadal Variability in the WACE and Its Oceanic Drivers
Abstract As the Earth warms, the “warm Arctic–cold Eurasia” (WACE) has changed noticeably, with enhanced interdecadal variability as the Arctic heats up, particularly over the Barents–Kara Sea region. Before the early 1980s, when Arctic warming was relatively weak, WACE was mainly influenced by Pacific temperature patterns (the Pacific Decadal ...

Predictability and dynamics of potential vorticity streamers and connections to high impact weather [PDF]
Narrow potential vorticity (PV) intrusions across the tropopause (PV streamers) are interconnected with surface high- and low- pressure systems and frequently present during high-impact weather in the mid-latitudes. They often form during the breaking of

Intermittently Forced Vortex Rossby Waves
Wavelike spiral asymmetries are an intriguing aspect of Tropical Cyclone dynamics. Previous work hypothesized that some of them are Vortex Rossby Waves propagating on the radial gradient of mean–flow relative vorticity.
