Warm Waves in North-Western Spitsbergen
Abstract In this study, weather conditions causing warm waves in north-western Spitsbergen, exemplified by Ny-Ålesund station, were analyzed. Between 1981 and 2010, 536 days with the maximum temperature exceeding 8.3°C (the value of 95 percentile) were selected. 37 warm waves, which altogether laste...
