According to an article on arstechnica.com, NOAA (National Oceanic and Atmospheric Administration) is making big changes to its global weather model. Recently, NOAA just appointed Brian Gross the new director of the Environmental Modeling Center, which deals with the forecasting models of the agency. The primary model used is the Global Forecasting System, which provides 7-10 day forecasts. The new model will implement an F3 core, which is a more computationally efficient model that allows the supercomputers to process the models more quickly, provide more rapid results, and allow the model to run at a higher resolution. The F3 model has been running in the background at the NOAA for the past year and it overall performs a bit better than the GFS model. There have been some problems with the F3 model, like its accuracy with predicting hurricane tracks and the amount of precipitation hurricanes have the potential of producing. Regardless, the change is very exciting and is projected to be better at predicting weather.
