Dr. David Sills, PhD

 
Professional ​
Overview
Executive Director - Northern Tornadoes Project
Department of Civil and Environmental Engineering
University of Western Ontario, London, ON

 

Research Interests

 

  • Tornadoes and other summer severe weather

  • Low-level mesoscale boundaries (including Great Lakes lake-breeze fronts and Alberta drylines)

  • Severe thunderstorm nowcasting
Research and Projects

Contributing to the protection of the lives and property of Canadians against severe and extreme weather

  • Tornadoes and their climatology via the Northern Tornadoes Project

  • Development of advanced techniques for severe thunderstorm nowcasting

  • 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)

 

Professional activities / interests

 

  • Serve on the WMO Nowcasting and Mesoscale Research Working Group

  • Serve on the ASCE EF-Scale Standards Committee

  • Serve as Associate Editor for the scientific journals Atmosphere-Ocean and Monthly Weather Review

  • Provide scientific reviews of journal manuscripts (e.g. Journal of Applied Meteorology and Climatology, Weather and Forecasting, Atmospheric Environment, Atmospheric Research, Boundary-Layer Meteorology, Journal of Wind Engineering and Industrial Aerodynamics, Hydrological Processes, Journal of Climatology, Quarterly Journal of the Royal Meteorological Society, Alternatives)

  • Transfer of science knowledge to meteorologists and engineers through dynamic presentations (e.g., change of season workshops, damage survey training sessions) and real-time interactive learning

  • Supervise and serve on defence committees for graduate students: York University, University of Manitoba, McMaster University, University of Western Ontario

  • Served on scientific committees for various professional meetings (e.g., 2017 CMOS Congress in Toronto, ON; 2016 and 2010 Great Lakes Operational Meteorology Workshops, Toronto, ON; 2007 UNSTABLE Science Workshop, Edmonton, AB; 2006 BAQS-Met Science Workshop, Toronto, ON; 2005 3rd MSC Forecasters Forum, Montreal, PQ)
