Why StormCaster

A new tool for understanding climate change in your community

In the last 50 years, there has been a 5% increase in average rainfall in the United States.

On a regional scale, the changes are substantial. In the Northeast, for example, there has been a 25% increase in average annual rainfall, while in the desert Southwest, there is a drop by as much as 40%. What’s more, the changes we have seen in rainfall are most pronounced in the extreme events. The size of large storms (the 100-year storm) has increased by as much a 66% over that timeframe (NOAA, 2010).

In light of these changes, a critical question is how will storms change in the future? StormCaster is a new online tool for forecasting storms, which affects your community in the 21st century. Using state-of-the-art general circulation models (GCMs) and historic rainfall observations, the tool allows you to select a location and generate a forecast from 2010-2100. Using the forecast can help you understand the projected trend in average rainfall in your community, and the projected changes in storms you experience every day.
