HRD Seminar – Dr. Andrew Hazelton (CIMAS/HRD) – 9 February 2022

Dr. Hazelton presented a seminar titled “Examining Hurricane Dorian's Early Intensification and Long-term Track Evolution Through an Ensemble of the Hurricane Analysis and Forecast System”. ABSTRACT: Hurricane Dorian (2019) was one of the strongest hurricanes on record in the Atlantic basin, and caused significant devastation across the northern Bahamas as it stalled out as a … Continue reading HRD Seminar – Dr. Andrew Hazelton (CIMAS/HRD) – 9 February 2022

Study on how Hurricane Dorian organized before rapidly intensifying published in Monthly Weather Review

This study showed that a weak, disorganized tropical system in an environment that is not primed for intensification can develop a new center where conditions are more favorable for intensification.  The ability to observe the center of circulation, the tilt of the vortex with height, the depth of the vortex, the wind shear, and locations … Continue reading Study on how Hurricane Dorian organized before rapidly intensifying published in Monthly Weather Review

Paper about how a new forecast model for hurricanes performed during 2019 published in Weather and Forecasting

This paper summarizes forecasts from an experimental forecast model called the Hurricane Analysis and Forecast System (HAFS) made during the 2019 Hurricane Season. HAFS is being developed for future use as an operational hurricane model to help forecasters predict what a hurricane is going to do. HAFS forecasts the weather on a set of points … Continue reading Paper about how a new forecast model for hurricanes performed during 2019 published in Weather and Forecasting

Study on the rapid intensification of Hurricane Dorian near the Eastern Caribbean published in Atmosphere

Summary:  We look at why Hurricane Dorian was able to intensify in the Eastern Caribbean when many forecasts suggested that it would stay weak and perhaps die out. To help answer this question, we use a forecast model called the Hurricane Analysis and Forecast System (HAFS).  Specifically, we use an ensemble, a group of forecasts … Continue reading Study on the rapid intensification of Hurricane Dorian near the Eastern Caribbean published in Atmosphere
