Research

 

Images and explanations from my research, newest at top. All images made with MATLAB (various versions) unless otherwise noted.

 
 

Atlantic 2009-2011

 

Real storms! Best track data gives the best after-the-fact estimate of TC track and intensity, and also archives the guidance given at the time (the forecasts). ATCF best track and guidance data courtesy of NOAA/NHC.

TC best track and guidance Igor (2010)
 

CM1 Model

 

Work using long (100-day) TC simulations from George Bryan's cloud resolving model CM1 (r15). Figures from AMS Tropical Meteorology Conference April 15-20 Ponte Vedra, FL. Manuscript with same work submitted to J. Atmos. Sci.

Last WRF run

 

WRF v3.2 run completed in Oct. 2010
Adaptive timestep: Fixed!
Moving nests: not moving as much!
Storm death: absent!
