HRD Seminar – Dr. Jon Poterjoy, HRD/NRC – Post-Doc Fellow – 30 March 2017
Dr. Poterjoy presented a seminar on “Progress and Lessons Learned During a Six-Month Collaboration with NOAA NSSL on Convective-Scale Data Assimilation”. ABSTRACT The nonlinear evolution of model forecast errors in convective weather regimes presents a major obstacle for predicting severe weather events. Ensemble forecasts provide an effective means of characterizing this uncertainty, which is a crucial step […]
105th Anniversary of the SS Koombana disaster
On 20 March, 1912, the passenger, cargo, and mail-carrying ship SS Koombana encountered a tropical cyclone off Western Australia, killing 74 passengers and 76 crew members. Most of the tale is known from the captain of the SS Bullarra that survived the disaster. Despite a falling barometer and a strong northeasterly wind, the Koombana departed Port Hedland […]
New and Improved SFMR data set
The technique to process data from the Stepped Frequency Microwave Radiometer (SFMR), which observes surface wind speeds and rain rates within tropical cyclones, was upgraded prior to the 2015 hurricane season on all NOAA and Air Force Reserve Command hurricane reconnaissance aircraft. The processing method improves the observations across all wind speeds and rain rates. Brad […]

HRD Seminar – Prof. John Molinari, University of Albany/SUNY – 7 March 2017
Prof. Molinari presented a seminar on “Outflow Layer Influences on Tropical Cyclones”. A recording of the presentation (audio begins 1 min into recording) is available on the anonymous ftp site: ftp://ftp.aoml.noaa.gov/hrd/pub/blog/seminars/2017/Molinari_HRD_Seminar_20170307.mp4
Paper on easterly waves in the Eastern Pacific that can form into tropical cyclones published in The Journal of the Atmospheric Sciences
“Easterly waves” are areas of low air pressure in the tropics that move westward and may become tropical cyclones. The most well-known type of easterly wave is the “African easterly wave,” which moves from West Africa north of the equator into the Atlantic Ocean and sometimes into the Pacific. Although almost all Northeast Pacific tropical […]
HRD researchers contribute to new textbook on recent advances in tropical cyclone research
The book, co-edited by HRD scientist Sundararaman Gopalakrishnan, is based on a series of lectures by scientists from the US, India and Australia, at a workshop held in Bhubaneswar, India on 9-14 July 2012. It provides information on recent advances in tropical cyclone (hurricane and typhoon) observations, data assimilation (the process of getting these observations […]
HRD Seminar – Kelly Ryan, CIMAS and AOML/HRD, NSSL, Norman, OK – 10 February 2017
Kelly Ryan presented a seminar titled “OSSE Evaluation of the Impact of Aircraft Observations on Hurricane Analyses and Forecasts” at the NOAA National Severe Storms Laboratory NSSL. ABSTRACT Each year, NOAA/AOML’s Hurricane Research Division (HRD) conducts its Hurricane Field Program in which observations are collected via NOAA aircraft to improve the understanding and prediction of hurricanes.
