Dynamical drivers of Greenland blocking in climate models
(Journal article; Peer reviewed, 2021)Blocking over Greenland is known to lead to strong surface impacts, such as ice sheet melting, and a change in its future frequency can have important consequences. However, as previous studies demonstrated, climate models ... -
Front–orography interactions during landfall of the 1992 New Year's Day Storm
(Journal article; Peer reviewed, 2020)Although following a common synoptic evolution for this region, the 1992 New Year's Day Storm was associated with some of the strongest winds observed along the Norwegian west coast. The narrow wind band along its bent-back ... -
High-resolution stable isotope signature of a land-falling atmospheric river in southern Norway
(Journal article; Peer reviewed, 2021)Heavy precipitation at the west coast of Norway is often connected to elongated meridional structures of high integrated water vapour transport known as atmospheric rivers (ARs). Here we present high-resolution measurements ... -
Intermittency of Arctic–mid-latitude teleconnections: stratospheric pathway between autumn sea ice and the winter North Atlantic Oscillation
(Journal article; Peer reviewed, 2020)There is an observed relationship linking Arctic sea ice conditions in autumn to mid-latitude weather the following winter. Of interest in this study is a hypothesized stratospheric pathway whereby reduced sea ice in the ... -
Polar lows – moist-baroclinic cyclones developing in four different vertical wind shear environments
(Journal article; Peer reviewed, 2021)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 ... -
Reconstructing winter climate anomalies in the Euro-Atlantic sector using circulation patterns
(Journal article; Peer reviewed, 2021)The efficacy of Euro-Atlantic circulation regimes for estimating wintertime climate anomalies (precipitation and surface temperature) over Europe is assessed. A comparison of seasonal climate reconstructions from two ... -
Relative importance of tropopause structure and diabatic heating for baroclinic instability
(Journal article; Peer reviewed, 2021)Misrepresentations of wind shear and stratification around the tropopause in numerical weather prediction models can lead to errors in potential vorticity gradients with repercussions for Rossby wave propagation and ... -
Resampling of ENSO teleconnections: accounting for cold-season evolution reduces uncertainty in the North Atlantic
(Journal article; Peer reviewed, 2021)We re-examine the uncertainty of the El Niño–Southern Oscillation (ENSO) teleconnection to the North Atlantic following the investigation of Deser et al. (2017) (DES2017). Our analyses are performed on the November–December ...
