DOI: 10.1007/s00382-019-04642-2
Abstract: Marine Cold-Air Outbreaks (MCAO) can be used as a large-scale measure of the potential for development of Polar Lows in the Northern North Atlantic Ocean during NH winter. We applied an MCAO index to 30… read more here.

DOI: 10.1175/mwr-d-16-0333.1
Abstract: AbstractRepresentation of polar lows in the new high-resolution Arctic System Reanalysis (ASR) was for the first time assessed and compared to that in the ERA-Interim. Substantial improvements were found in the 850-hPa relative vorticity and… read more here.
