An Objective Classification of Synoptic Types over Europe
A synoptic classification scheme is developed for Europe based on an automated two-step cluster analysis. It employs daily NCEP-NCAR reanalysis data over 62 years (1948–2009) in creating synoptic types from surface and upper air (1,000, 850, 700 and 500 hPa) temperature and humidity data as well as geopotential height and winds aloft. The synoptic types that have been created exhibit distinct seasonal preferences.
