JEDI: The Future of Data Assimilation

The process by which observational data is brought into models is called data assimilation (DA). The Joint Effort for Data assimilation Integration (JEDI) is the next generation, unified DA framework under collaborative development between NOAA and cross-agency partners through the Joint Center for Satellite Data Assimilation (JCSDA). JEDI will allow for a faster development and…

Saildrones Track Hurricanes to Gather Data for Forecast Improvement

In partnership with NOAA, Saildrone Inc. is deploying seven ocean drones to collect data from hurricanes during the 2022 hurricane season with the goal of improving hurricane forecasting.  For the first year, two saildrones will track hurricanes in the Gulf of Mexico. One of the biggest challenges to hurricane forecasting is predicting rapid intensification, when hurricane…

NOAA Awards $5.7 Million to Improve Hazardous Weather Forecasts

Research to focus on improved prediction of tornadoes, hurricanes, floods, snow NOAA Administrator Kathryn Sullivan announced today $5.7 million in cooperative research agreements and grants to improve the forecasting of hazardous and extreme weather including tornadoes, hurricanes, heavy rainfall, floods and snowstorms. The funding, provided by NOAA Research, will support collaborative work between NOAA and 27…

NOAA’s Investments in Weather Models and Partnerships Paying Off

As the Northeast digs out from this week’s blizzard, a new NOAA-led effort to improve the forecasting of such high impact weather events is reaching an important early benchmark. One of the first major improvements – upgrading the resolution of three global forecast models — has already shown its effectiveness. One of these models, the newly upgraded Global Forecast System (GFS) model, provided one of the most precise forecasts of the track, intensity, precipitation, and distribution of the Nor’easter.
