CA Drought Emergency

California Governor Edmund G. Brown Jr. Declares Drought Emergency.

SAN FRANCISCO – With California facing water shortfalls in the driest year in recorded state history, Governor Edmund G. Brown Jr. today proclaimed a State of Emergency and directed state officials to take all necessary actions to prepare for these drought conditions.

“We can’t make it rain, but we can be much better prepared for the terrible consequences that California’s drought now threatens, including dramatically less water for our farms and communities and increased fires in both urban and rural areas,” said Governor Brown. “I’ve declared this emergency and I’m calling all Californians to conserve water in every way possible.”

Researchers find climate link to atmospheric river storms

Climate Oscillations Linked to Atmospheric River Events

November 25, 2013

Climate Oscillations

High and low-pressure anomalies on the map (red=high, blue=low) are typical of combined negative phases of the Arctic Oscillation and Pacific/North American teleconnection.

A new research study has found a link between large-scale climate features and the occurrences of atmospheric river events. The research team was led by Bin Guan from UCLA and NASA’s Jet Propulsion Laboratory. They discovered that the occurrence of a negative phase in both the Arctic Oscillation (AO) and the Pacific/North American (PNA) teleconnection is associated with an increase of atmospheric river events over California. The paper was recently published in the journal Water Resources Research and can be accessed here.

CW3E Hosts Strategic Planning Meeting with Sonoma County Water Agency

CW3E Hosts Strategic Planning Meeting

October 10, 2013


CW3E and SCWA Meeting

The new CW3E at Scripps Institution of Oceanography (SIO) hosted a strategic planning meeting with the SCWA to identify common interests between SCWA’s needs for targeted science, technology and applications development and the CW3E mission. The meeting focused on current SCWA issues such as reservoir operations and a discussion of planned and ongoing projects such as the NOAA Regional Integrated Sciences and Assessment (RISA) program at SIO (the California-Nevada Climate Applications Program CNAP) and the HydroMeteorology Testbed (HMT). Strategic directions and specific next steps were addressed at the meeting.

The photo above shows several of the meeting attendees (from left to right): Brad Sherwood (SCWA), Jay Jasperse (SCWA), Rob Cifelli (NOAA), Grant Davis (SCWA), Marty Ralph (Scripps), Dave Reynolds (CIRES) and Carl Morrison (SCWA).

CW3E Director Addresses DWR/NWRI Drought Workshop

CW3E Director Addresses Drought Response Workshop

October 08, 2013

Dr. Ralph

High and low-pressure anomalies on the map (red=high, blue=low) are typical of combined negative phases of the Arctic Oscillation and Pacific/North American teleconnection.

Dr. Marty Ralph, Director of the Center for Western Weather and Water Extremes, briefed the Drought Response Workshop organized by the California Department of Water Resources (DWR) and the National Water Research Institute (NWRI) in Irvine, CA. The purpose of the workshop was to review and provide updates on drought planning, response and mitigation measures. Dr. Ralph introduced the new CW3E and discussed it’s mission as well as providing insight on the topic of drought.

A PDF document of Dr. Ralph’s presentations slides can be downloaded here.

A video of the talk is available here.

An overview of the conference and links to other presentations is available at the NWRI website.
