Paper on the Doppler Wind Lidar, a new instrument to measure wind from hurricane hunter aircraft, published in the journal Sensors
Summary: A new instrument, called an airborne Doppler Wind Lidar (ADWL, for short), was flown on NOAA’s hurricane hunter aircraft into two storms during 2016. This instrument measures winds above and below the plane. The ADWL measures wind where radar on the aircraft cannot: the radar can measure the wind where there are clouds or … Continue reading Paper on the Doppler Wind Lidar, a new instrument to measure wind from hurricane hunter aircraft, published in the journal Sensors
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 low-level downdrafts and their impact on intensity published in Monthly Weather Review
Summary: In this study, we looked at radar, thermodynamic (temperature and humidity), and sea surface temperature data from the National Oceanic and Atmospheric Administration Hurricane Hunter and National Aeronautics and Space Administration aircraft in Hurricane Earl (2010). We found that there are different types of downdrafts (air moving downward) near the strongest part of the … Continue reading Paper on low-level downdrafts and their impact on intensity published in Monthly Weather Review
Paper on turbulence near the ocean surface in Hurricane Rita published in the Journal of the Atmospheric Sciences
Summary:Knowing what is happening in the boundary layer of a hurricane (the area from the ocean surface up to about 1 km height) is very important for making accurate forecasts of how strong the hurricane will get. But measuring temperature, moisture, and wind so close to the ocean surface is dangerous and difficult. In the … Continue reading Paper on turbulence near the ocean surface in Hurricane Rita published in the Journal of the Atmospheric Sciences
