Coupled atmosphere–ocean observations of a cold‐air outbreak and its impact on the Iceland Sea Open
Marine cold‐air outbreaks (CAOs) are vigorous equatorward excursions of cold air over the ocean, responsible for the majority of wintertime oceanic heat loss from the subpolar seas of the North Atlantic. However, the impact of individual C…

Linking Sub‐Tropical Evaporation and Extreme Precipitation Over East Antarctica: An Atmospheric River Case Study Open
We investigate an intense snowfall event between 15 and 18 February 2011 over the East Antarctic coastal region which contributed to roughly 24% of the annual snow accumulation. The event was previously associated with an atmospheric river…

Characteristics of Cold Air Outbreak events and associated Polar Mesoscale Cyclogenesis over the North Atlantic region Open
Equatorward excursions of cold polar air masses into ice-free regions, so-called Cold Air Outbreaks (CAO), are frequently accompanied by the development of severe mesoscale weather features. Focusing on two key regions, the Labrador Sea an…

Polar lows – moist-baroclinic cyclones developing in four different vertical wind shear environments Open
Polar lows are intense mesoscale cyclones that develop in polar marine air masses. Motivated by the large variety of their proposed intensification mechanisms, cloud structure, and ambient sub-synoptic environment, we use self-organising m…

An evaluation of surface meteorology and fluxes over the Iceland and Greenland Seas in <span>ERA5</span> reanalysis: The impact of sea ice distribution Open
The Iceland and Greenland Seas are a crucial region for the climate system, being the headwaters of the lower limb of the Atlantic Meridional Overturning Circulation. Investigating the atmosphere–ocean–ice processes in this region often ne…

Polar Lows Open
Polar lows are intense maritime mesoscale cyclones developing in both hemispheres poleward of the main polar front. These rapidly developing severe storms are accompanied by strong winds, heavy precipitation (hail and snow), and rough sea …

Characteristics of Cold Air Outbreaks and associated Polar Mesoscale Cyclones in the North-Atlantic region Open
<p>Geographically confined, equatorward excursions of cold air masses into ice-free regions account for the majority of oceanic heat loss in key regions for deepwater formation in the North Atlantic. These cold-air outbreaks (CAO) ar…

The Iceland Greenland Seas Project Open
The Iceland Greenland Seas Project (IGP) is a coordinated atmosphere–ocean research program investigating climate processes in the source region of the densest waters of the Atlantic meridional overturning circulation. During February and …

High-Latitude Dynamics of Atmosphere–Ice–Ocean Interactions Open
The workshop on Dynamics of Atmosphere–Ice–Ocean Interactions in the High Latitudes attracted 90 scientists who met to 1) identify challenges in polar prediction, 2) explore our understanding of the coupled climate system in the high latit…
