Abstract

This study presents an automated or so-called objective circulation pattern classification for the region of the Svalbard archipelago on the basis of gridded NCEP/NCAR-reanalysis data. Self-organizing maps were set up. After evaluating the results for all clusters, the AA. decided to use 9 circulation patterns for further analysis. They show that the different circulation patterns derived in this study nicely represent seasonal states of the atmosphere. Within seasons, significant deviations of surface air temperature and precipitable water content are associated with the different weather types. The latter fact points to a broad applicability of this circulation pattern classification for studies that address the impact of interannual atmospheric variability on other parts of the geo-system such as glaciers, ice caps and vegetational patterns
