Recent secular variations in the extent of Northern Hemisphere snow cover

Abstract: Northern hemisphere snow cover during !988 and 1989 was at its lowest extent since the advent of reliable satellite snow-cover monitoring in 1972; running some 8-! 0% below the eighteen-year annual mean of 25.7 million km 2. Monthly minima for the period of record occurred six times during these two years. In general, the last nine years of the satellite record had less extensive cover than the 1972-80 interval. Negative anomalies during the 1980s were largest over Eurasia in all seasons, and in the Spring ove… Show more

“…During the most recent 27 years of the CDR, mean annual SCE has continued to exhibit lower snow extents relative to the data period ending in mid-1987. This step change in NH SCE was first identified by Robinson and Dewey (1990).…”

“…The extent of snow cover in the Northern Hemisphere has decreased significantly over the past decades because of global warming (Robinson and Dewey, 1990;Brown and Robinson, 2011). Snow cover showed the largest decrease in the spring, and the decrease rate increased for higher latitudes in response to larger albedo feedback (DĂŠry and Brown, 2007).…”
