Last week NOAA introduced the newest weather and climate supercomputers with an operational run of the National Blend of Models.


The new supercomputers will provide a significant upgrade to computing capacity, storage space and interconnect speed of the system.


The new supercomputers will allow forecasters to better forecast small-scale features like severe thunderstorms.


Additionally, there will be an upgrade to the U.S. Global Forecast System (GFS) this fall and the launch of a new hurricane forecast model that is expected to be in operation for the 2023 hurricane season.


These new computers are three times faster than the older system.
