Paper on turbulence near the ocean surface in Hurricane Rita released online 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 …

Paper on the direct measurement of important air-sea interaction parameters in tropical cyclones published in the Journal of Geophysical Research

Summary:Friction is what happens when two things rub up against each other; when this happens, they release heat. When this happens in the atmosphere, we call it “dissipative heating.” Tropical cyclones (TCs) mainly gather energy from the warm ocean at the boundary layer, the region from the surface of the ocean to an altitude of …

Paper on the new Doppler Wind Lidar on the NOAA Hurricane Hunters published in Remote Sensing

Summary: The warm ocean provides the energy for tropical cyclones to form and intensify. Knowing what is happening in the air immediately above this warm ocean (called the boundary layer) tells us how that energy gets into the air. So, it is important to know what is happening there to accurately predict how strong a …

AOML and HRD researchers at 33rd AMS Conference on Hurricanes and Tropical Meteorology, Ponte Vedra, FL – 15-20 April 2018

Thirty-one AOML and HRD scientists participated in the recent 33rd AMS Conference on Hurricanes and Tropical Meteorology in Ponte Vedra, FL, as authors or co-authors on 65 presentations and 19 posters. Roughly 783 presentations (507 oral presentations in 67 sessions and 276 posters in 2 session) were submitted to the conference. Of the 567 TC-related presentations …

Paper on how small-scale changes in winds in hurricanes impact hurricane forecasts published 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 …
