HRD Seminar – Dr. Jeff Kepert, Bureau of Meteorology, Melbourne, Australia – 23 April 2018

Dr. Kepert presented a seminar titled “Bias correction of tropical cyclone size and structure in the ECMWF global ensemble prediction system". ABSTRACT: Global EPS systems provide very valuable warning of severe weather risk, including tropical cyclones. One limitation arises because the spatial resolution of the EPS is necessarily too coarse to capture the fine details …

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 …
