Why Atmospheric Science?

Weather prediction, modelling and climate science: these are the big contributions made by the work of Atmospheric Scientists throughout their careers. Atmospheric Scientists study, learn and master the science behind the functioning of our natural world, and devise models to help us anticipate them. Thanks to the work of these scientists, we can gather increasingly accurate data about weather systems, effects on the natural environment , and effects on everyday human activity.

In a world that is steadily seeing the effects of global warming and climate change, Atmospheric Scientists are key in understanding the severity of our situation, and predicting the factors which can help mitigate them.

Notable alumni and faculty: Dr. Tom McElroy, who devised the UV Index employed in weather prediction today, Dr. Peter Taylor, whose work on the impact of Lake Erie Wind Farms on Water Temperature and Mixed-Layer Depths was published on the front cover of the March issue of the Journal of Geophysical Research.

Important Note:

Please email your queries to Prof. Gary Klaassen, : gklaass@yorku.ca

Atmospheric Science explores meteorology from the turbulent micro scale to the large synoptic scale weather systems. In our program, you will learn how we use computer models to forecast the weather and will develop a deeper understanding of the processes that drive severe weather, climate and climate change. You can top off your degree with a Certificate in Meteorology.

Courses You’ll Take:

• Geophysics and Space Science
• Cloud Physics and Radar Meteorology
• Numerical Weather Prediction
• Climate and Climate Change
• Remote Sensing of the Atmosphere
• Foundational Courses in Chemistry, programming, applied calculus, linear algebra and physics
• Applied courses in programming
• Applied courses in statistics, calculus and numerical prediction
• Applied courses in physics, atmospheric chemistry
• Applied courses in meteorology, spatial analysis, geography
• A final year research course

York graduates from both our Atmospheric Science stream and our one-year Certificate of Meteorology have been employed by:

• Environment and Climate Change Canada’s Meteorological Service
• The Weather Network
• Ontario Ministry of the Environment and Climate Change
• Government agencies for Natural Resources
• Risk management in the insurance industry

EECS 1011, Computational Thinking Through Procedural Programming and Mechatronics, 3 Credits

The objectives of 1011 are threefold: providing a first exposure to procedural programming, teaching students a set of computing skills (such as reasoning about algorithms, debugging and hardware interfacing and interaction), and demonstrating how computers are used in a variety of engineering disciplines. It uses problem-based pedagogy to expose the underlying concepts and experiential laboratory activities and projects to implement them. An integrated computing environment (such as MATLAB) is used so that students can learn key programming concepts(such as variables and control flow) without being exposed to complex or abstract constructs. The problems are chosen with consultation with the various engineering disciplines in the Faculty with a view of exposing how computing is used in these disciplines. In support of program-related objectives, WHMIS I and Active Bystander training will take place in this course.
