Characteristics of Cold-Air Outbreak Events and Associated Polar Mesoscale Cyclogenesis over the North Atlantic Region
Terpstra, Annick; Renfrew, Ian A.; Sergeev, Denis (Journal article; Peer reviewed, 2021)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, ... -
Dynamical Perspectives on the Formation and Intensification of Polar Lows
Terpstra, Annick (Doctoral thesis, 2014-11-25)This thesis consists of a collection of scientific publications addressing dynamical aspects of the formation and intensification of polar lows. Polar lows are small scale, intense, short-lived cyclones developing over ... -
An evaluation of surface meteorology and fluxes over the Iceland and Greenland Seas in ERA5 reanalysis: The impact of sea ice distribution
Renfrew, Ian A.; Barrell, C.; Elvidge, A.D.; Brooke, J.K.; Duscha, Christiane; King, J.C.; Kristiansen, Jørn; Cope, T. Lachlan; Moore, George William Kent; Pickart, Robert S.; Reuder, Joachim; Sandu, I.; Sergeev, Denis; Terpstra, Annick; Våge, Kjetil; Weiss, A. (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 ... -
The Iceland Greenland seas project

Linking Sub-Tropical Evaporation and Extreme Precipitation Over East Antarctica: An Atmospheric River Case Study
Terpstra, Annick; Gorodetskaya, Irina V.; Sodemann, Harald (Journal article; Peer reviewed, 2021)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 ... -
Polar lows – moist-baroclinic cyclones developing in four different vertical wind shear environments
Stoll, Patrick; Spengler, Thomas; Terpstra, Annick; Graversen, Rune (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 ...
