Common Community Physics Package v6.0.0 released to the public

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,”...

NOAA wind forecasts result in $150 million in energy savings every year

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...
