Snow water equivalent variability and forecast in Lithuania
Atmosphere circulation is the most important modulator of snow cover parameters. This study deals with the relation between the dominant Northern Hemisphere circulation mode, called the Arctic Oscillation (AO), and the spatial distribution of the snow water equivalent (SWE) within the territory of L...
