Director
Professor Roland Stull

I am a Professor of Atmospheric Science. As director of the Weather Forecast Research Team (WFRT), my goal is to improve numerical weather prediction and apply it to the benefit of society. I also have extensive experience in atmospheric boundary layers, turbulence, dispersion, and air quality. I am a Certified Consulting Meteorologist, and fellow of both the Canadian Meteorological & Oceanographic Society (CMOS) and the American Meteorological Society (AMS).

Our 20-member team focuses on making high-resolution, real-time daily, operational ensemble numerical weather forecasts (NWP) for all of Canada, with emphasis on the complex terrain of western Canada. We use both dedicated in house computer clusters and remote cloud computing for our forecasts. This work is sponsored by a wide range of agencies and clients, including the Canadian federal government, provincial and territorial governments, regional and local governments, national and regional nonprofit organizations, energy industries, transportation industries, a wide range of consulting companies.

In addition to operational daily NWP, we do extensive research, including field work utilizing suites of specialized sensors including new instruments we have devised (rocketsonde buoy system, expendable smoke and weather sensors), theoretical work on atmospheric behavior and smoke dispersion, development of machine learning algorithms for big data analysis, and research on ensemble NWP. Our productivity can be seen in our roughly 120 journal publications and extensive participation in technical conferences.

As a professor, I also have fun teaching courses at all levels. Our newest course ATSC 413 is on Forest Fire Weather & Climate. I also led the development of ATSC 313 Renewable Energy Meteorology and ATSC 113 Weather for Sailing, Flying, and Snow Sports. Each year I teach ATSC 201 Meteorology of Storms, and I help teach EOSC 114 Natural Disasters. In the past I’ve taught ATSC 303 on weather instruments, and ATSC 212 on Computer Programming for Atmospheric & Oceanic Sciences. On alternating years I teach grad courses ATSC 507 Numerical Weather Prediction Meteorology, and ATSC 595D Atmospheric Dispersion Modeling. I am also the author of two textbooks: “Practical Meteorology: An Algebra-based Survey of Atmospheric Science” which is free online, and “An Introduction to Boundary Layer Meteorology.”

But I am most proud of my research team. See their bios below.

Dr. Henryk Modzelewski

I have been with WFRT since the beginning. I started as a PhD student doing research in turbulence modelling and, after completing my PhD in 2004, I stayed with the team as Research Associate. I have been interested in modelling aspects of atmospheric physics from the very beginning of my research journey. First in modelling of air-pollution transport and expanding to broader aspects of numerical weather prediction with focus on turbulence models. Over the years my duties moved from research towards end-user application aspects of weather forecasting. Currently, I work part-time for the team and I am mostly involved in special projects for users of our forecasts as well as in maintaining our real-time forecast operations.

I joined the WFRT in September 2021 as a PhD student. I am from Edmonton, AB where I completed my BSc (Hon.) in Atmospheric Science from the University of Alberta and completed an undergraduate thesis focused on shoaling internal solitary waves. I then went on to complete a MSc where I studied sea ice model sensitivities in the Canadian Arctic. I have had a passion for weather from a young age and have enjoyed following and predicting severe weather on the prairies. My interest in weather prediction grew when I obtained an undergraduate position with Environment and Climate Change Canada. Here, I assisted in tracking and gathering reports of severe weather across the prairies to be used for weather warnings and bulletins. During this time, I grew my love for numerical weather prediction and boundary layer processes. My research interests are primarily focused on mountain meteorology, boundary layer parameterizations, as well as turbulent orographic form drag and physically based stochastic parameterizations. In my free time I love to run, hike, and read novels; I am also growing my mountaineering skills for future trips to the mountains.

I am a PhD candidate in Atmospheric Science, working under Prof. Stull as a researcher specializing in numerical weather prediction (NWP). Much like many of the other researchers on this team, my interest in weather started from a young age. However, my focus started narrowing towards NWP when I first worked under Roland as an undergraduate research assistant in 2014. After having graduated with a BSc. (Hon.) in Atmospheric Science at UBC, I joined the team full-time as a graduate student. My research is on improving multi-scale weather prediction on unstructured meshes, specifically on spherical centroidal Voronoi tessellations (SCVT). I have expertise with installing and running the Weather Research and Forecasting (WRF) model and the Model for Prediction Across Scales (MPAS), and leveraging cloud-computing technologies such as the Google Cloud Platform to run such models within a high-performance computing (HPC) context. I also serve as an assistant sys admin on the team, and have experience working with a variety of weather- and air-quality-related software. Outside of work, I enjoy hiking, reading, and video games (though, unlike what most people would expect, I have not played Heavy Rain).

In May 2021 I had the pleasure of joining UBC’s Atmospheric Science master’s program. As of December 2020, I received a Bachelor of Science from Virginia Polytechnic Institute and State University in Blacksburg, Virginia. During my undergraduate studies, I focused on dynamic, mesoscale, and synoptic meteorology, along with minors in geographic information science and geography. Within this time I discovered my passion and curiosity for severe weather, specifically extreme precipitation and tornadic events. During the summer of 2019, I had the opportunity to experience such severe weather firsthand, as I participated in the Virginia Tech Great Plains Storm Chase. This experience led me to pursue a semester-long study on synoptic-scale and mesoscale characteristics that take part in focusing and intensifying precipitation during flash flood events. At UBC I hope to learn and apply machine learning techniques to identify environmental conditions most conducive to severe weather in complex terrain such as in British Columbia. Outside of my studies, you will typically find me exploring nature, painting, or baking.
