HRD Seminar – Dr. Dave Raymond, New Mexico Institute of Mining and Technology – 12 December 2018

Prof. Raymond presented a seminar titled “Control of Convection in High-Resolution Simulations of Tropical Cyclogenesis”. ABSTRACT: Three idealized high-resolution simulations of tropical storm formation from a weak vortex are analyzed. The three simulations include a case using warm rain microphysics, a case in which surface friction is omitted, and a case in which ice microphysics … Continue reading HRD Seminar – Dr. Dave Raymond, New Mexico Institute of Mining and Technology – 12 December 2018

Paper on the tropical cyclone diurnal cycle as seen in a forecast model released online in Monthly Weather Review

Summary: As tropical cyclones (TCs) move across the oceans, they begin to expand each day around sunset, with clouds reaching hundreds of miles from the center by the following afternoon. This daily “exhale” of the clouds is a feature of what we call the TC diurnal cycle. This study looks at the this cycle in … Continue reading Paper on the tropical cyclone diurnal cycle as seen in a forecast model released online in Monthly Weather Review

Paper on possible improvements to forecasts from additional radio-occultation satellite data published in Monthly Weather Review

Summary: The Constellation Observing System for Meteorology, Ionosphere, and Climate (COSMIC) are a set of satellites that were launched in 2006 and 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 measure temperature and moisture with high accuracy every 100 … Continue reading Paper on possible improvements to forecasts from additional radio-occultation satellite data published in Monthly Weather Review
