Paper on the impact of using Hurricane Hunter data in the HWRF model released online in Monthly Weather Review

We studied how Hurricane Hunter aircraft observations can improve tropical cyclones forecasts from the National Oceanic and Atmospheric Administration's Hurricane Weather Research and Forecast (HWRF) model. Important Conclusions: Hurricane Hunter aircraft data generally improve HWRF forecasts. These improved forecasts are mainly in weak storms, since, without the data, HWRF often forecast storms that are too … Continue reading Paper on the impact of using Hurricane Hunter data in the HWRF model released online in Monthly Weather Review

HRD Seminar – Dr. Andrew Kren, CIMAS and AOML/HRD – 27 June 2018

Dr. Kren presented a seminar titled “Observing System Simulation Experiments (OSSEs) and Observing System Experiments (OSEs) to evaluate the impact of current and future observing systems in the NCEP GDAS”. ABSTRACT: Observing System Experiments (OSEs) test the impact of current observing system platforms on analyses and forecasts, while Observing System Simulation Experiments (OSSEs) can evaluate … Continue reading HRD Seminar – Dr. Andrew Kren, CIMAS and AOML/HRD – 27 June 2018
