Advancing scientific understanding of climate, improving society’s ability to plan and respond
The research aims to measure unusual intensities and frequencies of pre-industrial and recent El Nino events, providing insight into changes in the climate of North America.
The study, recently published in Nature Communications, will provide insight into the sensitivity of climate models to volcanic forcings.
During the winter of 2014 and 2015, the US west coast (USWC) experienced record high temperatures extending from Baja California to the Gulf of Alaska. This record warming, as high as 3°C in some areas, greatly impacted the California Current System (CCS) and Gulf of Alaska marine ecosystems. However, tropical Pacific sea surface temperature anomalies were weak during 2014, calling into question their role in the USWC warming period.
The MAPP-funded study finds that ENSO, PDO, and other sources of abnormal sea surface temperatures serve as predictors for U.S. seasonal mean precipitation and that these sources change seasonally and decadally.
Research led by MAPP supported PI, Dr. Suzana Camargo, examined the impact of volcanic aerosols on recent global tropical cyclone activity in observations, reanalysis, and models (including the CMIP5 multi-model).
The Madden-Julian Oscillation (MJO) is responsible for major shifts in tropical weather on weekly and monthly timescales with impacts around the earth.
In a paper published on the Journal of Climate, Chiodi (University of Washington) and Harrison (PMEL) analyze the value of wind stress information from the TAO/TRITON array, which has been deployed for over two decades.
The Modeling, Analysis, Predictions, and Projections and Climate Variability and Predictability programs will co-sponsor the Forecasting ENSO Impacts on Marine Ecosystems of the US West Coast workshop on August 10 and 11 in San Diego, California.
A multimedia report is now available for the 2015 El Niño Conference held November 17-18, 2015 in Palisades, NY. NOAA’s Climate Program Office co-sponsored this conference, in partnership with the World Meteorological Organization (WMO), the International Research Institute for Climate and Society (IRI) and the US Agency for International Development (USAID).
