Study: Warming brings more precip to VC, less to NorCal

Kim Lamb Gregory for the Ventura County Star reports on a new study based on an almost unimaginably vast dataset that looks at precipitation records from around the continental U.S. over the last sixty years. It's called When It Rains It Pours: Global Warming and the Increase in Extreme Precipitation from l948-2011. Lamb writes that it finds global warming is now bringing more and wetter storms to most of the country, especially New England, and most definitely including Ventura County. She talked to Bernadette del Chiaro, who speaks for the state's climate change research and policy center':

Heavy downpours that used to happen once every 12 months on average now happen every 10.7 months statewide, Del Chiaro said.

The snowstorm that closed the Grapevine in 2011, the La Conchita
mudslide in 2005 and the numerous floods and uprooted trees in Ventura
County can be linked to global warming, Del Chiaro said.

The story then goes into solutions and politics, but there's more to the science that isn't much discussed in the story, and actually not so much in the study either. Fortunately, the study includes some interesting graphs and tables.

That large increase in the lower central coast area must be the Santa Barbara/La Conchita/Ventura County region the spokesperson mentioned. The study also graphs the increase in precip against a statistical control without global warming:

And perhaps most interesting of all, if not especially visual, it puts the results in table form, and reveals that Northern California and especially Oregon have seen a striking decrease in precipitation.

This comes as a surprise. Would like to figure out why that might be.
