HRD scientists Eric Uhlhorn and Lisa Bucci participated in the 9th annual CBS4 Weather Day Thursday before the Miami Marlins vs. Philadelphia Phillies game at Marlins Park. Local elementary- and middle-school students participated in the fun-filled, science-focused field trip. The program is designed to teach the kids basic concepts of weather and climate and how these […]
Frank presented a seminar on “Understanding Hurricane Sandy’s Track and Intensity Changes” Abstract Between 24-29 October 2012 Hurricane Sandy developed and moved northward out of the central Caribbean Sea, across eastern Cuba, over the eastern Bahama Islands and just off the east coast of the United States, and finally re-curving westward until making landfall in southern […]
On May 20, 1999 a severe tropical cyclone made landfall at Shah Bunder, Pakistan, near Karachi. The cyclone was at its peak with estimated 1-minute sustained winds near 110 kt (127 mph, 204 kph). Heavy rains and a tremendous storm surge caused most of the damage, with the approximate $6 million devastation done to the […]
Jun presented a seminar on “Asymmetric hurricane boundary layer structure relative to the wind shear from dropsonde composites” Abstract: This talk presents the asymmetric structure of the hurricane boundary layer in relation to the environmental vertical wind shear in the inner core region. GPS dropsonde data deployed by research aircraft in 19 hurricanes are analyzed in […]
Paul and Altug each presented a seminar: “Evaluation of shear-relative hurricane structure from the HWRF model” – Paul Reasor Abstract: This talk will present a composite-based analysis of shear-relative hurricane structure from the HWRF model. The model’s representation of shear-relative precipitation and kinematic structure are evaluated using a recently-published composite of such structure diagnosed from airborne […]
Tomi presented a seminar on “What is parameterization uncertainty and how to evaluate it for ensemble prediction?” Abstract: It is widely accepted that parameterizations of sub-grid scale processes in Numerical Weather Prediction (NWP) models are uncertain and that this leads to forecast errors. The impacts of parameterization uncertainty have been demonstrated by numerous sensitivity studies in […]
The HRD Model Development Team (pictured above) was recognized by the South Florida Federal Executive Board with the Scientific Employee of the Year award at their annual May meeting. They were praised for their contributions in developing the advanced high-resolution Hurricane Weather Research and Forecasting (HWRF) model that is used operationally to provide forecast guidance to the […]
Eric presented a seminar on: “Hurricane Wind Speed Asymmetries and Relationships to Motion and Environmental Shear” Abstract: Wavenumber-1 wind speed asymmetries in 35 hurricanes are quantified in terms of amplitude and phase, based on aircraft observations from 128 individual flights between 1998 and 2011. The impacts of motion and 850-200 mb environmental vertical shear are examined […]
May’s Science meeting had 1 presentation: Paul Reasor: Comparison of G-IV and P-3 TDR Analyses from Gabrielle (2013) The presentation is available on the anonymous ftp site at: ftp://ftp.aoml.noaa.gov/hrd/pub/blog/meetings/2014/science/HRD_SciMeet_20140508.pptx
BOMEX logo On May 1, 1969, the Barbados Oceanographic and Meteorological EXperiment (BOMEX) was launched. The three month-long experiment was carried out in and around the West Indian island of Barbados. Seven U.S. Government agencies cooperated in gathering weather and ocean data in an effort to measure the exchange rate of heat, moisture, and […]
