A digital archive of the historical Tiksi meteorological station data (1934 to present) has recently been created for air surface temperature, surface pressure, wind velocity, and cloudiness. A detailed analysis of the Tiksi data has been performed showing the influences of synoptic systems and cloudiness on temperature trends and shore fast ice cycles (presented as a companion paper in this session). In this study, the identical statistical methods are applied to the Barrow, Alaska meteorological data sets. Although the data sets for Barrow started at the beginning of the 20th century, the data were not collected with the same temporal regularity as the Tiksi data (4 times/day) until the 1960s; so this latter period is the focus of comparisons
