While large swathes of the planet are warmer than normal this March, there are some exceptions. One of those exceptions being Antarctica and Greenland where it’s been colder than normal.

Following the crazy warmth of February, March has unsurprisingly produced little winter thanks to a strong jet stream throwing one low after another across Ireland and the UK. A strong, cold polar vortex and MJO has driven the positive-neutral NAO with the Western Europe door wide open. This aided Northern Ireland, Denmark and Sweden to […]
Northern Ireland gets wettest March in first 18 days of the month thanks to strong polar vortex, MJO
The combination of strong/cold polar vortex, an increased thermal gradient over North America coinciding with phases 2, 3 and 4 of a strong MJO has driven a highly active Atlantic storm pattern across Ireland, UK and Denmark. Northern Ireland, Denmark and Sweden have witnessed their wettest March on record. Unusually strong and cold polar vortex. […]

This storm could […]
