Northern Ireland gets wettest March in first 18 days of the month thanks to strong polar vortex, MJO

Written by on March 22, 2019 in Rest of Europe, United Kingdom & Ireland with 0 Comments

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 of course is OPPOSITE of last March!

The NAO has been consistently on the positive side of neutral likely due to the phase 3 and 4 of the MJO.



As well as rain. It’s also been rather windy at times.
