Snow Cover

Note: Global warming is increasing the moisture content of the atmosphere due to warmer oceans. This could manifest as an increase in snow extent. The warmer atmospheric temperatures altering season lengths should melt the snow faster in the spring. The data does indicate this to be true. We will add to this section if direct attribution studies are conducted.

Arctic Oscillation GEFS Forecasts

The ensemble mean forecasts of the AO index are obtained by averaging the 11 GFS ensemble members (blue lines), and the observed AO index (black line) is superimposed on each panel for comparison. For the forecasted indices (lower 3 panels), the yellow shading shows the ensemble mean plus and minus one standard deviation among the ensemble members, while the upper and lower red lines show the range of the forecasted indices, respectively.

Global_Annual_MB Fig. 1 Annual mass balance of reference glaciers with more than 30 years of ongoing glaciological measurements. Annual mass change values are given on the y-axis in the unit meter water equivalent (m w.e.) which corresponds to tonnes per square meter (1,000 kg m-2).
