Relation between the snow accumulation on glaciers of North-West Spitsbergen and the atmospheric circulation, precipitation and air temperature in the winter seasons

Abstrakty
This work attempts to determine connections between glaciers' winter mass balance and meteorological factors of winter seasons. Detailed analysis was carried out between the snow accumulation of Austre Broggerbreen and the meteorological data from Ny-Alesund station (Kongsfjord region) from 1975 to 1998. Relation has been found between the snow accumulation and warm and humid air masses frequency in winter seasons (X - V). Those masses are mainly from southerly and southwesterly directions for Svalbard. The winter mass balance shows very clear connection with air temperature and precipitation factors of winter seasons (sum of winter precipitation, number of days with precipitation intensity >= 5 mm per day, winter mean air temperature, and number of days with maximum daily air temperature >= 0°C). A particularly close connection is observed between winter mass balance and number of days with precipitation intensity >= 5 mm per day at the positive daily maximum air temperature (LPTmax) (r = 0.81) - Fig. 8. The winter mass balance multiply regression (Wb) was worked with the use of the elementary meteorological factors: the average winter temperature (T) and the sum of precipitation in the same period (P). On the basis of the multiply regression of winter balance it is possible to predict snow accumulation changes. Over the next 50 years the winter snow accumulation of Austre Broggerbreen could increase about 15% if the scenario of climatic changes by Hanssen-Bauer (2002b) is used. If, in addition, one assumes the stability of ablation, the mass balance of glaciers will rise by 24%, but the mass balance will still be negative.
