Characteristics of cyclones following different pathways in the Gulf Stream region
(Journal article; Peer reviewed, 2021)The Northwest Atlantic is a region of strong temperature gradients and hence is a favourable location for wintertime cyclone intensification co-located with the storm track. The temperature gradient is associated with both ... -
Coupled atmosphere–ocean observations of a cold-air outbreak and its impact on the Iceland Sea
(Journal article; Peer reviewed, 2023)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 ... -
Cyclone Intensification in the Kuroshio Region and its relation to the Sea Surface Temperature Front and Upper‐Level Forcing
(Journal article; Peer reviewed, 2021)The Northwest Pacific features strong sea surface temperature (SST) gradients providing favourable conditions for wintertime cyclone intensification in the midlatitudes. To estimate the relative contribution of the SST ... -
Dynamics of concurrent and sequential Central European and Scandinavian heatwaves
(Journal article; Peer reviewed, 2020)In both 2003 and 2018 a heatwave in Scandinavia in July was followed by a heatwave in Central Europe in August. Whereas the transition occurred abruptly in 2003, it was gradual in 2018 with a 12-day period of concurrent ... -
An evaluation of surface meteorology and fluxes over the Iceland and Greenland Seas in ERA5 reanalysis: The impact of sea ice distribution
(Journal article; Peer reviewed, 2021)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 ... -
Formation of maritime convergence zones within cold air outbreaks due to the shape of the coastline or sea ice edge
(Journal article; Peer reviewed, 2022)Maritime cold air outbreaks often feature convergence zones that provide a conducive environment for the development of polar mesoscale cyclones and polar lows. This study examines the formation mechanisms of these convergence ... -
Impact of sea spray-mediated heat fluxes on polar low development
(Journal article; Peer reviewed, 2024)Sea spray, originating from wave breaking under high wind conditions, can significantly affect turbulent heat fluxes at the air–sea interface. Even though polar lows (PLs) can become extreme weather features with gale-force ... -
Large‐scale regional model biases in the extra‐tropical North Atlantic storm track and impacts on downstream precipitation
(Peer reviewed; Journal article, 2019)Global climate models have circulation biases that the community aims to reduce, for instance through high‐resolution dynamical downscaling. We used the Weather Research and Forecasting model (WRF) to downscale both ... -
The link between eddy-driven jet variability and weather regimes in the North Atlantic-European sector
(Peer reviewed; Journal article, 2017-10)This study reconciles two perspectives on wintertime atmospheric variability in the North Atlantic–European sector: the zonal‐mean framework comprising three preferred locations of the eddy‐driven jet (southern, central, ... -
On the effect of nocturnal radiation fog on the development of the daytime convective boundary layer: A large-eddy simulation study
(Journal article; Peer reviewed, 2022)The potential effect of failing to predict nocturnal deep radiation fog on the development of the daytime convective boundary layer (CBL) is studied using large-eddy simulations. Typical spring and autumn conditions for ... -
The stable atmospheric boundary layer over snow-covered sea ice: Model evaluation with fine-scale ISOBAR18 observations
(Journal article; Peer reviewed, 2022)A realistic representation of the stable atmospheric boundary layer in numerical weather prediction (NWP) and climate models is still a challenge. We study the evolution of a stable boundary layer over snow-covered sea ice ... -
Unravelling the March 1972 northwest Greenland windstorm with high-resolution numerical simulations
(Peer reviewed; Journal article, 2019-08-07)Thule Air Base in northwest Greenland experienced an extreme windstorm during the night of 8/9 March 1972. The event is not among official WMO records because the anemometer broke after recording the highest gust of 93 m s−1. ...
