Projected change in winter and summer rain and snowfall for the late 21st century (2070-2090 relative to 1960-1990)
All models and scenarios project that Arctic rain and snowfall will increase throughout the 21st century. These increases are larger than projected for the rest of the world. There are distinct regional patterns within the Arctic. There will be somewhere between 5% and 70% more rain or snowfall in the period 2080-2099, depending on where you are in the Arctic and which emissions scenario is used. The greatest relative increases in rain or snowfall will be in winter and autumn, and the smallest in summer.
Despite the increases in rain and snowfall, Arctic land areas are generally expected to dry out more during summer. This is partly because warmer air results in more evaporation from the surface.
