AB: This study examines the relationships between the frequency of snowfall, rainfall, mixed solid and liquid, and wet days (including all forms of precipitation) and the air temperature at 80 stations over northern Eurasia during 1936-89 to understand potential changes in precipitation frequency and types under a warming climate over high- latitude land areas. The results suggest that both the snowfall and rainfall days increase as air temperature increases during winter, but decreases during spring. While in the fall, the snowfall day decreases but rainfall day increases and overall less precipitation days as air temperature increases. The study also show that snowfall day would suddenly switch to decrease with air temperature when winter air temperature reach a certain threshold.
