Atmospheric river landfall-latitude changes in future climate simulations
The latitude of landfall for atmospheric rivers (ARs) is examined in the fully coupled half-degree version of the Community Climate System Model, version 4 (CCSM4) for warm future climate simulations. Specifically, two regions are examined: U.S. West Coast/North Pacific ARs and United Kingdom/North...
