Subseasonal to Seasonal Research (S2S) significantly aids decision support across industries and also provides the knowledge necessary for forecasters and emergency managers to keep the public informed and prepared for weather phenomena.
Subseasonal to Seasonal Research (S2S) is a priority area for NOAA and the US congress due to its ability to fill emerging forecast needs in various economic sectors. This is reflected in two primary goals identified by NOAA and in the Weather Research and Forecasting Innovation Act of 2017 (the Weather Act). The S2S program works to:
With new advances in forecasting, traditional weather models are pushed to predict further and further into the future. Global climate models are implemented at broader spatial and temporal resolution. This leaves a gap for prediction timescales of two weeks to two years, commonly referred to as the Subseasonal to Seasonal timescale.
The S2S program works to improve forecasts models by funding projects that:
The S2S program additionally funds and coordinates aspects of the ongoing North American Multi-Model Ensemble (NMME), an interagency/intergovernmental ensemble of coupled models from centers in the US and Canada, providing data for global, 12-month forecasts of 13 key variables. NMME data is used for multiple forecast needs.
Mark Olsen, the S2S Program Manager at WPO, is serving as the Co-Chair for a poster session at the Ocean Sciences Meeting in New Orleans. The poster session D044A – Recent Progress in Advancing Global Coupled Ocean Models Poster will be held Thursday, February 22 from 4 to 6 p.m. in the Poster Hall, First Floor (NOLACC).
This project aims to enhance the realism of global ocean and sea ice simulations by implementing a version of the Modular Ocean Model version 6…
The 12th Symposium on Weather, Water, and Climate Enterprise will be held at the American Meteorological Society (AMS) 104th Annual Meeting. The Subseasonal to Seasonal…
WPO is proud to share the news that seven members of our team have been recognized as recipients of the OAR 2023 awards.
The primary objectives are to review and evaluate the current capabilities and advancements of the NMME in addressing the challenges of seasonal climate predictability; and…
The Ocean Prediction Center (OPC) rolled out its experimental Week 2 Marine Hazards Outlook in mid-March, providing guidance about the chance of certain wave heights and wind speeds at longer lead times. Because of the demand for information about wind and wave hazards beyond the upcoming week, OPC meteorologists researched…
A presentation given at NOAA’s 46th Annual Climate Diagnostics and Prediction Workshop used cluster analysis methods to investigate and forecast circulation regimes impact on weeks 3/4 predictions. This study demonstrates that the dominant circulation regimes over North America are combinations of teleconnections where the clusters are related to temperature and…
A recent study uses novel diagnostics to evaluate the ability of 11 state-of-the-art Subseasonal to Seasonal (S2S) forecast systems to represent the teleconnections of the Madden-Julian Oscillation (MJO) and the impact on mid-latitude weather systems and prediction. Several S2S program funded projects contributed to this work. While highlighting where model…
