AbstractA simulation of projected changes in December to February precipitation
from the period 1975 to 1995 to the period 2080 to 2100 is presented here. On
average, precipitation increases, but it is not evenly distributed geographically.
There are marked regions of decreasing, as well as increasing precipitation,
over both land and ocean. Annual average precipitation generally increases over
northern continents, and particularly during the winter. Warmer surface temperature
would speed up the hydrological cycle at least partially, resulting in faster
evaporation and more precipitation. The results are based on climate change
simulations made with the Coupled Global Climate Model developed by Environment
Canada.
