The influence of mid-latitude cyclones on European background surface ozone.

ABSTRACT: The relationship between springtime mid-latitude cyclones and background ozone (O₃) is explored using a combination of observational and reanalysis data sets. First, the relationship between surface O₃ observations at two rural monitoring sites on the west coast of Europe - Mace Head, Ireland and Monte Velho, Portugal - and cyclone track frequency in the surrounding regions is examined. Second, detailed case study examination of four individual mid-latitude cyclones and the influence of the associated frontal passage on surface O₃ is performed. Cyclone tracks have a greater influence on the O₃ measurements at the more northern coastal European station, Mace Head, located within the main North Atlantic (NA) storm track. In particular, when cyclone
