Paper on how getting turbulence correct in forecast models can improve intensity forecasts in sheared storms released online in Monthly Weather Review
Summary: Though tropical cyclones (TCs) are usually hundreds of miles across, the strongest wind occurs in gusts that can be smaller than 100 yards across, or the size of a football field. We call features that cover such a small area the “turbulent scale.” Other features that are important in forecasting TCs can be as … Continue reading Paper on how getting turbulence correct in forecast models can improve intensity forecasts in sheared storms released online in Monthly Weather Review

HRD Seminar – Kyle Ahern, Florida State University – 4 September 2018
Mr. Ahern presented a seminar titled “Observed and Simulated Boundary Layer Structures in the Hurricane Inner-core During Intensity Change”. ABSTRACT: GPS dropwindsonde data from Atlantic basin aircraft reconnaissance missions (Hock and Franklin 1999) between 1998 and 2015 are gathered to construct composites of the hurricane inner-core boundary layer during modes of intensity change. Sounding information … Continue reading HRD Seminar – Kyle Ahern, Florida State University – 4 September 2018

Paper on how eyewall replacement cycles start published in The Journal of the Atmospheric Sciences
Summary: When hurricanes become strong, they sometimes form a second eyewall around the main eyewall. This second ring of strong winds and heavy rain means that strong, damaging winds could cover a larger area than before. However, it also means that the storm might temporarily weaken. Understanding and predicting this process is therefore very important. … Continue reading Paper on how eyewall replacement cycles start published in The Journal of the Atmospheric Sciences
