Researchers have for years been working to tackle the subseasonal to seasonal (S2S) prediction problem to improve forecasts. The Subseasonal Experiment, SubX, is an interagency research-to-operations project designed to help tackle this problem. The results of the project were recently published in BAMS. 

New research, funded by CPO's Climate Variability and Predictability Program, shows that warming of the Indo-Pacific Ocean is altering rainfall patterns from the tropics to the United States, contributing to declines in rainfall on the United States west and east coasts.

A research team funded in part by CPO's MAPP and CVP Programs investigate the effect of global warming on the MJO. 

MAPP's Fall 2019 Newsletter is here! Read up on what's happening in the program this quarter, including research highlights! 

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.
