This study examines the impact of assimilating Doppler Wind Lidar (DWL) data on hurricane prediction in the operational Hurricane Weather Research and Forecasting system. A series of experiments were conducted to identify the best way to assimilate the DWL data in comparison to assimilation of Tail Doppler radar data. A new data thinning method was … Continue reading Paper on assimilating Doppler wind lidar and Doppler radar data into a hurricane model published in Remote Sensing
The study introduces a new database that is freely available and consists of over 900 airborne Doppler radar analyses collected between 1997–2020. We demonstrate the capabilities of the database by identifying how the structure of hurricanes changes depending on the strength of the storm, which provides a foundation for future research avenues and computer model … Continue reading Paper describing large new airborne Doppler radar dataset in tropical cyclones released online in Monthly Weather Review
This paper explores the effect of mountainous terrain on the structure of a tropical cyclone eyewall by using a numerical model to simulate the landfall of a typhoon in the Central Mountain Range (CMR) of Taiwan and its reemergence over water after crossing the CMR. It was found that the presence of the CMR disrupted … Continue reading Study on the impact of mountains on rainfall and intensity of tropical cyclones published in Monthly Weather Review
April's science meeting consisted of two presentations: Sim Aberson: The polygonal eyewall of Hurricane Fabian Robert Rogers: Characteristics of Aligning Weak Tropical Cyclones Copies of the four presentations are available here.
This study uses NOAA airborne Doppler radar data to tie together the many different characteristics of convective rainband updrafts that have been documented, both by observations and from modeling studies. The results help shed light on how these updraft circulations are organized and what underlying dynamics might contribute to the observed organization. You can access … Continue reading Paper on observations of updrafts in hurricanes from NOAA Hurricane Hunter aircraft published in The Journal of Geophysical Research
The document aligns with AOML's three goals: Goal 1: Empower Our Team. Create an inclusive and cutting-edge environment that fosters discovery, exploration, and success. Goal 2: Observe the Earth System: Collect and evaluate ocean, atmosphere, and marine ecosystem observations that contribute to the body of scientific knowledge of the Atlantic Ocean region to improve the ability to … Continue reading AOML releases Accomplishments for 2021

February's science meeting, co-hosted by the National Hurricane Center (NHC), provided an update on developments of the Hurricane and Ocean Testbed (HOT), a new facility at NHC dedicated to facilitating the transition of research and development projects to operations in a physical space. For many years, NHC partnered with NOAA’s Office of Oceanic and Atmospheric Research via … Continue reading HRD Monthly Science Meeting of 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
