Svalbard’s Mesoscale Environmental Factor Impact on the Wind Field

The mesoscale circulation along the west shore of Spitsbergen is largely controlled by difference in temperature between glaciers and surface sea temperatures. We describe how effect influences atmospheric patterns. conducted research was based on reanalysis data, model measurements; wind data from different sources scales were compared analysed. discuss situations wherein can be identified analysing direction or its velocity. This study shows role Svalbard region. Different according to patterns taken a catalogue 21 types for each day created are analysed with cases land-sea breeze type 20-year period 1994 2013. It proved that even if it not possible distinguish this local large-scale directions, factor observed studying speeds. claimed as long there Spitsbergen, will air over land water.
