25th Anniversary of Hurricane Andrew striking South Florida

In the early morning hours of August 24, 1992, Category-Five Hurricane Andrew roared across southern Florida leaving behind a trail of devastation that stunned the nation.  Andrew was the first hurricane of this ferocity to hit the continental United States since Hurricane Camille in 1969, and repercussions of its landfall were felt in the world …

HRD Seminar – Dr. Jason Dunion, CIMAS and AOML/HRD – 4 May 2017

Dr. Dunion presented a seminar titled  “The Tropical Cyclone Diurnal Cycle: The Great Hurricane Exhale". Abstract: New geostationary infrared satellite imagery has revealed a curious diurnal pulsing pattern in tropical cyclones (TCs) that may represent an unrealized, yet fundamental process of mature TCs.  These diurnal pulses begin forming in the storm's inner core near the time …

Paper on forecast improvements due to dropsonde data from the Global Hawk aircraft published in Monthly Weather Review

Starting in 2010, the National Aeronautic and Space Administration and the National Oceanic and Atmospheric Administration have used the Global Hawk, an unmanned aircraft that can fly at 65,000 feet for 24 hours at a time, to make observations in tropical cyclones. The Global Hawk can release dropsondes that measure temperature, humidity, pressure, and wind …
