This month, a research team, funded in part by CPO's Climate Observations and Monitoring Program and Modeling, Analysis, Predictions, and Projections Program, published an update to a weather “time machine” they’ve been developing since 2011. This third version of the 20th Century Reanalysis Project, or 20CRv3 for short, is a dauntingly complex, high-resolution, four-dimensional reconstruction of the global climate that estimates what the weather was for every day back to 1836.
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.
A new review paper describes how MAPP-funded and organized work has contributed to recent progress in understanding tropical cyclones.
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.
A new study shows significant potential in using atmospheric patterns to forecast coastal flooding that occurs without rainfall during high tides.
Americans’ health, security and economic wellbeing are tied to climate and weather. Every day, we see communities grappling with environmental challenges due to unusual or extreme events related to climate and weather.
