Mike Dettinger, Marty Ralph, Paul Neiman, and several compadres have done a great job illustrating the importance of atmospheric rivers in the weather and climate of the west coast. In Dettinger et al. (2011) they present a fantastic analysis of the contribution of atmospheric rivers to the hydroclimate of the western United States.

From Dettinger et al. (2011).
Thus, we have just submitted a short paper to Atmospheric Sciences Letters expanding the Dettinger et al. (2011) analysis to include those atmospheric rivers. Indeed, this does result in a substantial increase in precipitation related to atmospheric rivers over the southwest especially southern Arizona. Compare the results of our gridded analysis below to their analysis above based on station data (for details, see the paper).
