Typhoon Vicente made landfall in Southern China late on 23 July, 2012, as a category-4 typhoon, the strongest to hit southern China in recent years. Six days earlier, an area of cloudiness east of the northern Philippines started to slowly organize. As it passed into the South China Sea, it gained enough intensity and organization […]
On 14 July, 1997, Tropical Storm Claudette was moving northeastward offshore the east coast of the US. Eager to test the new Gulfstream-IV (G-IV) jet aircraft and the new Global Positioning System dropwindsonde, the National Hurricane Center tasked the first-ever operational synoptic surveillance mission geared toward improving track forecasts. Initial condition differences in the […]
Dr. Brammer presented a seminar titled “Tropical Cyclogenesis from African Easterly Waves: Observations and Predictability”. A recording of the presentation is available on the anonymous ftp site: ftp://ftp.aoml.noaa.gov/pub/hrd/blog/seminars/2017/Brammer_HRD_Seminar_20170718.mp4
Intensity Forecast Experiment (IFEX) Program Director Paul Reasor and HRD Director Frank Marks briefed the Aircraft Operations Center (AOC) personnel at their brand new facility at Lakeland Linder Regional Airport on IFEX plans for 2017 and Hurricane Forecast Improvement Project progress, respectively. The two presentations are available in a .zip archive on the anonymous ftp […]
These two papers analyze extreme upward air currents, called “convective bursts,” in hurricanes that have been believed to be important for hurricane intensification. We use the Weather Research and Forecasting (WRF) model to look at convective bursts in two hurricanes: Hurricane Dean from 2007 and Hurricane Bill from 2009. In the first paper, we study […]
NOAA’s Hurricane Research Division is beginning its daily map discussions on Monday, July 17th in support of its 2017 Hurricane Field Program. These discussions are led by scientists that report on the tropical weather and any features that are of interest for flight missions. We invite our remote collaborators to attend our daily discussions weekdays at […]
In July of 1847, William Reid, Royal Governor of Barbados, inaugurated a hurricane warning system on that island. As a colonel of the Royal Engineers, Reid had been assigned to Barbados to rebuild barracks destroyed by a hurricane in 1831. Seeing the vast destruction left by the storm spurred an interest in Reid, and he […]
July’s science meeting consisted of 6 presentations: Steve Guimond (NASA) – “Reviving the Imaging Wind and Rain Airborne Profiler (IWRAP) for Hurricane Research: A Case Study of Hurricane Rita (2005)” Mu-Chieh (Laura) Ko – “Preliminary Review – HWRF-B 2016 Retrospective Dataset” Robert Rogers – “The Challenge of Intensity Forecasting in Moderate Shear” Emily Paltz (Hollings […]
On June 30, 1502, during his fourth voyage to the New World, Christopher Columbus and his fleet sought shelter from a hurricane. While his fleet survived, a Spanish treasure fleet heading for home fared far worse. During his previous voyages to the Caribbean, Columbus had learned of the terrible storms that frequented the area. The […]
