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 …

HRD Seminar – Michael Fischer, University of Albany/SUNY – 9 February 2018

Michael presented a seminar titled  “Normalized Convective Characteristics of Tropical Cyclone Rapid Intensification Events in the North Atlantic and Eastern North Pacific”. Abstract The relationship between tropical cyclone (TC) convective characteristics and TC intensity change is explored using infrared and passive microwave satellite imagery of TCs in the North Atlantic and eastern North Pacific basins from …

Paper on the likely impact of the new COSMIC satellites on weather forecasts published in Monthly Weather Review

The Constellation Observing System for Meteorology, Ionosphere, and Climate COSMIC) is a set of satellites launched in 2006 that orbit the earth about 500 miles above ground. They use radio signals from Global Positioning System (GPS) satellites in a process called “radio occultation” to accurately measure temperature and moisture at a large number of points in …

HRD Seminar – Dr. David Ryglicki, Naval Research Laboratory – 17 August 2017

Dr. Ryglicki presented a seminar titled  “The Kinematics of Rapidly Intensifying Hurricanes in Moderate Vertical Wind Shear”. Abstract: A select group of tropical cyclones (TCs) which unexpectedly undergo rapid intensification in moderate vertical wind shear are identified, analyzed, and modeled. Geostationary satellite and reanalysis data are used to identify features and environmental parameters of these TCs. …
