The study focus on the influence on COLs interannual variability, of larger scale phenomena such as blocking events and other main circulation modes defined over the Euro-Atlantic region. It is shown that there is a very large interannual variability in the COLs occurrence at the annual and seasonal scales, although without significant trends. The influence of larger scale phenomena is seasonal dependent, with the positive phase of the NAO favoring autumn COL development, while winter COL occurrence is mostly related to blocking events. During summer, the season when more COLs occur, no significant influences were found. 0177-7971 10.1007/s00703-006-0222-7 https://hdl.handle.net/20.500.14352/50978 http://dx.doi.org/10.1007/s00703-006-0222-7 http://link.springer.com/ Interannual variability of cut-off low systems over the European sector: The role of blocking and the Northern Hemisphere circulation modes
