The variable here is that the Arctic area of the North Atlantic has a lack of observational data anyway and this has been commented on previously by NOAA, the upcoming pattern relies on the models calling this area correctly, they could overplay or underplay the extent of blocking in those regions.
Als ik het goed versta wil dit zeggen dat de blokkade boven de oceaan/Groenland onderschat kan zijn? Maar evengoed overschat.:)
