The NOAA flight season began early this year with an operational flight into a system, known as Potential Tropical Cyclone 2, that may soon develop into a tropical depression east of the Windward Islands. The plan for the season was recently released and is available online at https://www.aoml.noaa.gov/2022-hurricane-field-program/, and a kickoff meeting to discuss plans … Continue reading NOAA Hurricane Field Program begins with flights into Potential Tropical Cyclone 2 in the Tropical Atlantic
Dr. Leighton presented a seminar titled “Characterizing Raindrop Size Distributions Observed in Hurricanes”. ABSTRACT: One of the main applications of radar measurements is to estimate rainfall rate based on its power-law relationships with radar reflectivity. Different relationships have been obtained for different weather scenarios. Hurricanes, in comparison with other severe weather systems, have a much longer … Continue reading HRD Seminar – Dr. Hua Leighton (CIMAS/HRD) – 24 March 2022
April's science meeting consisted of four presentations: Xiaomin Chen: "Boundary Layer Recovery and Precipitation Symmetrization Preceding Rapid Intensification of Tropical Cyclones under Shear" Andy Hazelton: "HAFS Ensemble of Hurricane Dorian (2019): Early Intensity and Long-Term Track" Jon Zawislak: "Accomplishments of NOAA's Airborne Hurricane Field Program and a Broader Future Approach to Forecast Improvement" Kathryn Sellwood: … Continue reading HRD Monthly Science Meeting of April 2021
HRD scientists Frank Marks, Hua Leighton, and Sundararaman Gopalakrishnan worked on making this system reality.
The Annual Meeting is the world’s largest yearly gathering for the weather, water, and climate community. It brings together great minds from a diverse set of scientific disciplines – helping attendees make career-long professional contact and life-long friends while learning from the very top people in the atmospheric sciences. The 101st AMS Annual Meeting took place virtually … Continue reading HRD scientists participate in the 101st American Meteorological Society Annual Meeting
Summary: In order to accurately forecast the weather, models must accurately represent how liquid water and ice particles in cloud form, grow, and disappear, how big and how many of each there are. To do that, we must know how this all works in real clouds. The NOAA P3 Hurricane Hunter Aircraft have instruments called … Continue reading Paper on ice particles in tropical cyclones and how they are represented in forecast models published in Geophysical Research Letters
