Severe Weather Scientist - Investigating hazardous summer weather and techniques for forecasting/nowcasting
CURRENT S&T / RESEARCH
Contributing to Environment Canada’s mandate to protect the lives and property of Canadians against severe and extreme weather
- Low-level convergence boundaries (lake breeze fronts, thunderstorm gust fronts, drylines) and their relationship to severe weather (heavy rain, hail, damaging wind and tornadoes) and hazardous levels of air pollutants (ozone and particulate matter)
- Bridging the gap between meteorological research and operations via the Research Support Desk initiative at regional weather centres
- Development of advanced prototype tools and techniques for severe weather nowcasting such as the interactive Convective Analysis and Storm Tracking prototype
- Great Lakes lake breeze circulations / fronts and their climatology
- Tornadoes and their climatology
PROFESSIONAL ACTIVITIES / INTERESTS
Provide scientific reviews of journal manuscripts (e.g. Journal of Applied Meteorology and Climatology, Weather and Forecasting, Atmosphere-Ocean, Atmospheric Environment, Atmospheric Research, Boundary-Layer Meteorology, Journal of Wind Engineering and Industrial Aerodynamics, Alternatives)
Transfer of science knowledge to operational meteorologists through dynamic presentations (e.g., change of season workshops, damage survey training sessions) and real-time interactive learning (via the Research Support Desk)
Co-supervisor of the 1 PhD student and research work by other students via Dr. Peter Taylor at the Department of Earth and Space Science and Engineering, York University
