While no clear trends are evident from the climate projections over the study period, the timing,
or ‘seasonality’, of precipitation is another important part of the story because of its
influence on snowpack and timing of peak flows. These impacts are addressed later on in this storyline.
Precipitation, both amount and timing, is a critical factor in the water supply equation for the Big
Wood Basin. In particular, it heavily influences stream flows and determines snow and snow accumulation
- Precipitation has historically been highly variable and with continued variability projected into
- The warmer/wetter scenario seems to predict amplified wet years and dry years compared to the historical
- The other two climate scenarios show no clear trends in the amount of precipitation expected over
the course of a year.
The following chart show a summary of the basin average precipitation change for the entire Big
Wood Basin. You can "turn on" and "turn off" particular models by clicking on the
legend entries near the top of the chart. Clicking the buttons at the bottom of the chart also filter
the chart display by scenario. You can further filter the data displayed on the chart by entering a search
string in the "Filter" box near the bottom of the chart.
