New study helps track seasonal shifts in North Atlantic storm track
By Summit Voice
FRISCO — Just as weather forecasters in the western U.S. look at El Niño and La Niña to help get a handle on season outlooks, European meteorologists are carefully analyzing the North Atlantic Oscillation for climate clues. The job is easier in some years, according to a new study carried out by the National Oceanography Centre.
The research shwoed that the relationship between our winter weather and the strength of the airflow coming in from the Atlantic – one of the factors used by forecasters to predict the weather – is stronger in some years than others. The results were recently published in the Royal Meteorological Society publication Weather.
“There are two major atmospheric pressure systems centred around Iceland and the Azores that are very influential for the weather in Europe. Air flows between these two systems, bringing mild air from the North Atlantic to Europe,” said co-authors Joël Hirschi and Bablu Sinha from the National Oceanography Centre.
