Dr. Ron McTaggart-Cowan

Research Scientist - Numerical modelling and atmospheric dynamics

CURRENT S&T / RESEARCH - Research in numerical weather prediction from the local to the global scale, and for time scales ranging from minutes to seasons

  • Research on the use of high resolution models to produce forecast guidance
  • Development of coupled modelling systems for environmental prediction
  • Research into tropical/extratropical interaction, particularly in relation to the development of tropical cyclones from extratropical precursors
  • Research on the ability of mid and high resolution modelling systems to accurately predict the cyclogenesis and intensity of tropical cyclones
  • Evaluation of high resolution numerical guidance, particularly in regions of steep terrain


Lead of the Canadian contribution to the Mesoscale Alpine Project (MAP) Demonstration of Probabilistic Hydrological and Atmospheric Simulation of flood Events in the Alpine region (D-PHASE), a WMO Forecast Demonstration Project based in Switzerland

Member of the thesis committee for a doctoral student in tropical/extratropical interaction and tropical cyclogenesis
