Paper on the accuracy of surface windspeed analyses published in Monthly Weather Review

Summary:  Sometimes, the wind at the surface around a hurricane is the same around the storm center (what we call a symmetric pattern), and at other times, it is different (what we call an asymmetric pattern). In addition, sometimes the wind pattern stays the same, and sometimes it changes quickly. This study looks at how […]

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 how the region near the ocean surface impacts hurricane forecasts released online in Monthly Weather Review

 Summary: Forecasters and researchers use the Hurricane Weather Research and Forecasting (HWRF) model to forecast where a hurricane will go, how strong it will be, how large it will be, and where the strongest winds are. This paper looks at how winds close to the surface in hurricanes are transferred upward and how changes […]
