Dr. George (Trey) Alvey’s research is currently focused on tropical cyclone intensification, particularly during the early stages of tropical cyclone development. This includes subtopics such as vortex scale dynamics and vortex alignment. Other current research projects involve process based studies using Time-Resolved Observations of Precipitation structure and storm Intensity with a Constellation of Smallsats (TROPICS) and modeling studies with the Hurricane Analysis and Forecast System (HAFS).

Current Work

  • Radar analysis of tropical cyclone intensification and vortex-scale dynamics
  • Utilization of Time-Resolved Observations of Precipitation structure and storm Intensity with a Constellation of Smallsats (TROPICS) for thermodynamic information in relation to intensity change processes like vortex alignment
  • Early stage tropical cyclone dynamical studies using HAFS and investigations of track and intensity errors
  • Radar scientist and Lead Project Scientist for Advancing the Prediction of Hurricanes Experiment (APHEX)
