Paper on getting the best TC forecasts using NOAA’s G-IV released online in Monthly Weather Review

Summary: During each hurricane season, NOAA’s Gulfstream-IV (G-IV) Hurricane Hunter aircraft measures wind, temperature, humidity, and pressure in and around hurricanes threatening the United States.  An instrument called the dropwindsonde is released from the G-IV to collect the data as it falls to the ocean surface.  The plane currently flies where we expect observations from the … Continue reading Paper on getting the best TC forecasts using NOAA’s G-IV released online in Monthly Weather Review

AOML & HRD Seminar – Dr. Bo-Wen Shen, San Diego State University – 25 February 2019

Prof. Shen presented a seminar titled "Butterfly Effects and Chaos: New Insights Revealed by a Generalized Lorenz Model". Abstract Is weather chaotic? A view that weather is chaotic was proposed and is recognized based on the pioneering work of Prof. Lorenz who first introduced the concept of deterministic chaos. Chaos is defined as the sensitive … Continue reading AOML & HRD Seminar – Dr. Bo-Wen Shen, San Diego State University – 25 February 2019

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
