Spatial distribution and interannual variability of precipitation (snowfall and rainfall). Spatial distributions of the mean annual trends during the study period are represented in the study area (illustrated in Fig. 1) for a snowfall and b rainfall, in which hatching indicates statistically significant trends at the 90% confidence level. Panel c corresponding interannual variability for total precipitation, snowfall, and rainfall. The mean annual trends (values indicated in the figure with the associated p values) were calculated as area-weighted averages in each grid cell of the Arctic circumpolar river basins
