Oral presentation Towards seamless prediction


David Turner (NOAA Global Systems Laboratory)


The HRRR model is an operational storm-scale numerical weather prediction forecast system that has been updated approximately every 2 years since it was first introduced in 2014. This seminar gives a brief update on the evolution of the HRRR, with a focus of what is new for version 4 which will become the operational model in December 2020. I will also give an update of the future of operational storm-scale modeling in the US as NOAA moves towards a unified forecasting system.
