WRF Regional Climate Model simulated meteorology associated with large streamflow events in the PNW


Project description


Large runoff events, or floods, are of critical importance to public safety, commerce, and infrastructure. The WRF regional climate model simulates atmospheric conditions. Large streamflow events in the PNW are produced by precipitation events and snowpack melt. West of the Cascades, floods are generally driven by large storms moving onshore from the Pacific Ocean from mid-October to May. East of the Cascades, the largest flooding generally occurs in late spring, when atmospheric temperatures warm sharply and accelerate the melting snowpack.

In this figure, daily rainfall maps show the evolution of rainfall that drove the simulation period (1972-2000) peak flow for a medium-sized basin of western Washington.
