Common Community Physics Package v6.0.0 released to the public
NOAA’s current high-resolution weather model operates on a 3km grid, but how do we program the model to describe a 100-meter-wide cumulus cloud that grows into a thunderstorm? The cloud is too small for the model to represent it with equations of motion. The answer is by developing “physical parameterizations,” that make assumptions to describe ...

Major milestone: UFS Short-Range Weather Application 2.0.0 released on June 23 2022
Sample plot from the release version of the SRW application from test cases -- this example is from a high-resolution (3km) forecast over the CONUS on July 1, 2019 and shows how the updraft helicity and reflectivity coincide.Code sharing enables innovations in numerical weather prediction scienceThe Global Systems Laboratory (GSL) was a co-lead ...

GSL smoke products will transition to new NOAA supercomputer
The National Center for Environmental Protection (NCEP) is set to transition their suite of smoke forecast products to use NOAA Global Systems Laboratory’s Rapid Refresh (RAP) smoke model(RAP Smoke). The change will take place effective June 28th as a result of NCEP’s transition to a new supercomputer system.NOAA GSL’s Rapid Refresh has been ope...

Experimental forecast of dust from the Sahara Desert
The coupled global weather and chemistry research model, dubbed FV3-Chem, produces seven-day forecasts for a host of air quality impacts, including where dust will deliver hazy days and colorful sunsets, as well as potential breathing problems and other respiratory issues for sensitive populations. This video shows a forecast of dust from the Sa...

NOAA wind forecasts result in $150 million in energy savings every year
As electricity providers increasingly add renewable energy to their portfolio, a new study shows that more accurate wind forecasts generated by a NOAA weather model is saving the utilities, and hence the consumers, big money. While wind is abundant, it is also intermittent. Utilities need accurate wind forecasts in order to gauge electricity pro...

GSL innovations selected for new forecast model prototype
By Michael Toy, Shan Sun, Ning Wang, and Ligia BernardetNew versions of the Global Forecast System (GFS) and Global Ensemble Forecast System (GEFS) will be implemented in operations at the National Weather Service (NWS) in 2024. The GFS and GEFS are numerical weather prediction models widely used by forecasters in the NWS and private companies t...
