英文摘要	Trends in the duration or extent of snow cover are expected to feedback to temperature trends. We analyzed trends in dates of onset and termination of snow cover in relation to temperature over the past 27 years (1980-2006) from over 636 meteorological stations in the Northern Hemisphere. Different trends in snow duration are observed over North America and Eurasia. Over North America, the termination date of snow cover remained stable during the 27 years, whereas over Eurasia it has advanced by 2.6 +/- 5.6 d decade(-1). Earlier snow cover termination is systematically correlated on a year-to-year basis with a positive temperature anomaly during the snowmelt month with a sensitivity of -0.077 degrees C d(-1). These snow feedbacks to air temperature are more important in spring, because high net radiation is coupled with thin snow cover.; Environmental Sciences; Meteorology & Atmospheric Sciences; SCI(E); EI; 9; ARTICLE; 1; 8
