What is it about?
In January/February 2012, eastern Europe experienced persistent cold temperatures and snowstorms. The occurrence of a cold wave is not unusual in this region, but this period was remarkable for its duration and intensity.

Why is it important?
Large-scale cold extremes can cause high-impact weather, and they can pose a big challenge to societies and ecosystems as they are more difficult to cope with than changes in the mean temperature of a geographic region. This study investigates the salient features of the winter 2012 cold wave and the influence of large-scale atmospheric patterns. For this purpose: (i) a cold wave detection method which is based on spatially and temporally varying minimum temperature threshold is used; and (ii) two-dimensional atmospheric blocking detection method is employed.
Perspectives
I hope this artcile may give some insights into high-impact cold waves and climate variability.
