5th anniversary of Typhoon Vicente

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 […]

20th anniversary of the first operational synoptic surveillance mission with the NOAA G-IV

  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 […]

Two part paper on convective bursts in hurricanes published in Monthly Weather Review

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 […]

Paper on accounting for the location of dropwindsondes during measurements released online in the Journal of Atmospheric and Oceanic Technology

Summary: Hurricane Hunter aircraft have been releasing instruments called dropwindsondes to measure pressure, temperature, moisture, and wind speed and direction in hurricanes for two decades. Data from dropwindsondes released near the storms have led to better forecasts of where they will go, but improvements to forecasts of how strong they will get have lagged. Part […]
