Atmospheric Rivers (ARs) are narrow regions of extratropical water vapor transport, situated in the lower troposphere. They are responsible for a large proportion of poleward vapor transport from the tropics …
In many sea ice models, a single-category, zero layer thermodynamic scheme is employed, in which sea ice albedo is prescribed based on surface types depending on snow cover, surface temperature, …

As Earth system models (ESMs) grow in complexity and in volume of output data, there is an increasing need for rapid, comprehensive evaluation of their scientific performance. The upcoming Assessment …

Sea ice dynamics in numerical models are discretized on a spatial grid, with variables defined at grid cell vertices, edges, or centers. The CD-grid discretization places the velocity vector on …
The vast majority of studies examining the impact of freshwater from ice sheet melting on the Atlantic Meridional Overturning Circulation (AMOC) use climate models that cannot resolve mesoscale ocean processes …
Mesoscale eddies are abundant features in the Arctic Ocean, influencing ocean dynamics and stratification, transporting heat, salt, and nutrients, and modulating sea ice melting. In this study, we detect and …
Arctic freshwater is exported to the North Atlantic through Fram Strait and the Canadian Arctic Archipelago, and its partitioning influences subpolar ocean stratification. How climate warming will alter these export …
The ocean and sea ice are central to Earth’s climate system, influencing global heat and carbon cycles, weather patterns, and sea level rise. Recent decades have seen rapid advances in …

Mesoscale convective systems (MCSs) are large, long-lived thunderstorms that produce much of the rainfall in the tropics and subtropics, yet their role in southern African rainfall and lightning has remained …
Ocean eddies are ubiquitous in the ocean. Characterizing and quantifying their impact on the large-scale ocean circulation is key. Here we compute eddy-mean interactions for Conservative Temperature variance, including temperature …
