Paper on how small-scale changes in winds in hurricanes impact hurricane forecasts released online in Weather and Forecasting

Summary: Forecasters and researchers use the Hurricane Weather Research and Forecasting (HWRF) model to forecast where a hurricane will go, how strong and large it will be, and where the strongest winds will be. Wind in hurricanes are different over very short distances like 100 m, or the length of a football field, what is …

Paper on the difference between rapidly intensifying storms and those that don’t intensify as fast published in Journal of the Atmospheric Sciences

Summary: The main model that forecasters use to predict what a hurricane will do is the Hurricane Weather Research and Forecast (HWRF) model. Because we cannot measure what is currently happening in the hurricane exactly, we run the model many times at once with different measurements to get an idea of the different forecasts that …

HRD Seminar – Dr. Javier Delgado and Lisa Bucci, UM/CIMAS & HRD – 18 August 2017

Dr. Delgado and Ms. Bucci presented a seminar on "A 2 km Basin Scale Nature Run for a Hurricane Regional OSSE System". Abstract: A realistic Nature Run is the foundation to a useful Observing System Simulation Experiment (OSSE) framework.  A high-resolution, Basin Scale Nature Run (BSNR) using the Non-hydrostatic Multiscale Model on the B grid …

HRD Debrief for missions into Hurricane Franklin – 15 August 2017

HRD researchers discussed the results from the two P-3 and one Global Hawk mission into Hurricane Franklin (8-9 August 2017). The agenda for the discussion was: Mission Overview (Reasor) Science Discussions 20170808H1 (Zawislak) 20170809H1 (Rogers) EMC input (Sippel) Additional field program issues Slides from the debrief are available at: ftp://ftp.aoml.noaa.gov/pub/hrd/blog/meetings/2017/HFP/franklin17_debrief_main.pptx  

Mini-Dropwindsonde data from Global Hawk used in forecast models for the first time during Hurricane Franklin

For the first time, data from mini-dropwindsondes released by the Global Hawk aircraft were used by NOAA Global Forecast System to predict where Franklin might track, how strong it would get, and other weather around the globe.  A total of 48 mini-dropsondes were released by the Global Hawk on the morning and afternoon of 9 …
