Short summary
The 2013–2014 winter sea surface temperature (SST) was anomalously cool in the mid-North Atlantic region. We investigate the processes by which cyclones can lead to SST cooling and their contribution towards the 2013–2014 SST anomaly. We find that cyclones induce a cold wake, which extends along the cyclones' cold front. Cyclones account for over 40 % of the observed cooling in the mid-North Atlantic. Thus, cyclones play a major role in determining the extreme 2013–2014 winter SST cooling.
