Two new datasets, funded in part by NOAA Research’s Modeling, Analysis, Predictions, and Projections (MAPP) Program, now provide easy public access to 60 terabytes of climate forecasts containing predictions of rainfall, temperature, winds and other variables at the subseasonal level (two weeks to two months ahead).

New research, funded by CPO's Modeling, Analysis, Predictions, and Projections (MAPP) program, shows that the polar vortex has shifted towards more frequent weak states and fewer strong states over the past few decades, with subsequent cold extremes seen during Eurasian winters. 

As an important milestone for NOAA’s ongoing efforts, researchers from universities, NOAA OAR research laboratories and the National Weather Service (NWS) recently met to discuss efforts to improve S2S predictions.

A special issue on the interagency North American Multi-model Ensemble, a seasonal prediction system combining forecasts from the leading North American climate models, is now available. The papers in this special issue document a variety of different research uses of the NMME system database, which includes a 30-year set of hindcasts as well as real-time forecasts.  

Bridging the gap between short-term weather and long-term climate predictions has remained challenging for scientists, but public demand and promising research has focused NOAA's attention on this prediction problem. In an effort to further progress, researchers from universities, NOAA and other labs and centers will meet to highlight recent efforts to develop skillful predictions for the subseasonal to seasonal timescale.
