Atmospheric analysis of the cold late February and early March 2018 over the UK
A strong blocking anticyclone developed over Scandinavia through the last week of February and persisted into early March 2018, driving a bitter easterly wind from Siberia and bringing a severe cold outbreak and significant snowfall to the UK. A second spell of severe weather and low temperatures th...
