HRD Seminar – Dr. Sean PF Casey, CIMAS and AOML/HRD – 15 February 2018

Dr. Casey presented a seminar titled “Geostationary Hyper-Spectral Sounder (Geo-HSS) Constellation:  A Global Observing System Simulation Experiment (OSSE) Assessment”. Abstract Observing System Simulation Experiments (OSSEs) can provide quantitative assessments of potential impacts of new observation sources, without the instrument actually being built in some cases. This presentation describes the set-up of global-scale OSSEs, from the […]

HRD Seminar – Scott B. Sieron, Pennsylvania State University – 12 February 2018

Scott presented a seminar titled  “Mesoscale tropical cyclone model EnKF data assimilation of all-sky satellite radiances: advancing from IR to microwave”. Abstract Development with the WRF tropical cyclone configuration and EnKF data assimilation system at Penn State is ongoing towards supporting the direct assimilation of top-of-atmosphere microwave emission observations in all sky conditions. These observations relate […]

Paper on the difference between rapidly intensifying storms and those that don’t intensify as fast published in Journal of the Atmospheric Sciences

Summary: The main model that forecasters use to predict what a hurricane will do is the Hurricane Weather Research and Forecast (HWRF) model. Because we cannot measure what is currently happening in the hurricane exactly, we run the model many times at once with different measurements to get an idea of the different forecasts that […]

Lisa Bucci named NOAA Team Member of the Month

Lisa Bucci was honored this month for her courageous work last year during Hurricane Irma. Hurricane Irma was an extremely powerful and catastrophic hurricane — the most intense storm to strike the U.S. coastline since Hurricane Katrina in 2005. On the morning of September 7, 2017, the NOAA National Hurricane Center (NHC) issued hurricane watches […]
