| heal.abstract | In this study a methodology for grouping seasonal circulation types occurring over an area is introduced. This procedure combines the surface air mass characteristics affecting the area with the synoptic conditions prevailing over it. Factor Analysis and Cluster Analysis are used to derive the circulation types, based on surface meteorological data and surface pressure grid data. The methods are applied to Athens, Greece, using data over the period 1954-1999 for winter (December, January, February) and summer (June, July, August) seasons. The daily circulation types are analyzed at surface level and their temporal evolution is examined via transition matrices. 315 grid points are used covering the area between 25degrees N to 60degrees N and 10degrees W to 40degrees E. This analysis derives 8 circulation types for the winter and 4 for the summer. A reduction in cyclonic activity and an increase in anticyclonic activity in the Central Mediterranean are detected in the late 1980s and early 1990s during the winter period. During summer the etesian winds and the local flows are dominant over Athens. | en |
