A new study in the Nature Partner Journal Climate and Atmospheric Science describes a breakthrough in accurately predicting atmospheric river behavior several weeks ahead.

The SARP-funded work improved water utilities' ability to make decisions despite extreme conditions

Thanks to a team of scientists led by Nat Johnson, an Associate Research Scholar at NOAA’s Geophysical Fluid Dynamics Laboratory (GFDL) and the Cooperative Institute for Climate Science at Princeton University, NOAA’s forecasters at the Climate Prediction Center (CPC) now have a new tool that provides week 3-4 guidance for their precipitation outlooks, and even better guidance for their temperature outlooks — all while helping them understand what drives the weather we see several weeks from now.
