Prior to joining the University of Manitoba in 2001, I was an operational meteorologist with Environment and Climate Change Canada (formerly Environment Canada, when I was there) at the Prairie and Arctic Storm Prediction Centre (PASPC).
My Research Program
My work deals with convection processes, severe/extreme weather and climate, storms, and surface-atmosphere interactions. I use field measurements and numerical modelling to better understand the processes and interactions within these areas.
Field measurements consist of ground-based / satellite-based remote sensing along with rawinsondes for atmospheric profiling and examining cloud characteristics as well as fixed and mobile meteorological basic state variable measurements. Specialized equipment include: (1) profiling microwave radiometers and Doppler wind Lidars, (2) Atmospheric Mobile Measurement Observing Systems (AMMOS), (3) laser precipitation measurements, and (4) portable automatic weather stations.
A variety of numerical models are used in-house and in collaboration with other researchers including RDPS/HRDPS (Canadian models) and WRF (a U.S. mesoscale atmospheric model).
Students get the benefit of working with World-class research equipment and collaborate with researchers within Canada and abroad to expand their experience and training.
A combination of field measurements, remote sensing and numerical modelling are used to:
(1) understand the coupled nature of weather and climate processes;
(2) ensure the models simulate the environment properly (model validation);
(3) improve the physical processes within the models (physics and internal parameterizations).
University of Manitoba Weather Central Weather Information
I teach/co-teach the following
Atmospheric Thermodynamics, Clouds and Precipitation
Atmospheric Dynamics, Storms and Radar
/ GEOG 7780
/ GEOG 7420
Synoptic Meteorology and Weather Analysis (every 2nd year, alternates with 4330
/ GEOG 7332
Concepts in Atmospheric Modelling (every 2nd year, alternates with 4300
(grad course also available) Selected Issues: Severe Thunderstorms—storm chasing & field techniques (every 2nd year, summer)
The last course is Canada’s only for-credit storm chasing course - it is offered to UofM (and other university qualified) students and the general public - ask me about it if interested!
