Research Highlights

Research Interests

Airborne Doppler observations of tropical cyclones and convective phenomena.

Assimilation of the Doppler observations in simulations of tropical cyclones.

Methods to improve automated quality control of airborne Doppler observations, including the structure of first-guess fields used to improve real-time de-aliasing.

Observing System Simulation Experiments, particularly those designed to optimize collection of airborne data.

Dr. John Gamache was the leader of the HRD radar group, and continues to serve in the group, particularly as curator of the automated tail Doppler radar quality control and analysis software.  The primary purposes of the radar group are archiving and displaying the airborne radar data collected in hurricanes, evaluating their quality, and maintaining and developing software to quality-control, analyze, display, and transmit the data.  The two most significant contributions of the automated software are 1) real-time analyses for use by forecasters and quality-controlled data for assimilation in numerical models, and 2) the assistance to all who would use the data to improve basic understanding of tropical cyclones and other weather phenomena, by greatly reducing the workload to analyze the data.
