New research debunks link between solar cycle and North Atlantic winter weather

The video discusses the North Atlantic Oscillation (NAO) and its influence on winter weather patterns in Europe. A positive NAO results in mild, wet winters, while a negative NAO leads to snowy, cold winters. A theory suggests a link between the NAO and the solar cycle, proposing that solar activity could predict NAO patterns up to a decade in advance. However, research from Columbia University and Lamont-Doherty Earth Observatory found no evidence of this correlation before 1960, attributing the perceived link to atmospheric variability rather than solar activity.

What is the significance of the 11-year solar cycle in relation to the NAO?

What did scientists at Lamont-Doherty Earth Observatory find regarding the correlation between the NAO and solar activity?
