Meteorologists do more than just predict the weather for our daily lives. They analyze the physics of the atmosphere and its interactions with land and water. Weather forecasts play a critical role — not just in our health and safety, but also in supporting our local environments, economies and ecosystems.
Cody Knight, a meteorologist specializing in power demand and renewable energy forecasting, shares his insights into the science of weather prediction. He also looks at the unique challenges that come with navigating Calgary’s unpredictable weather the city’s famous for, including chinook winds that can warm temperatures upwards to 20 and 30 degrees Celsius in the middle of a winter freeze, summer hail storms and other mountain meteorology occurrences.
“People should feel fairly confident about hourly forecasts during the same day, or even out a few days whether it’s issued from their local TV meteorologist or from a government source like Environment Canada, ” says Knight.
Knight notes there are times when the hourly forecast can be incorrect, especially when it comes to the exact amounts of snowfall and its onset or end. Still, he believes that, “It’s always better for people to just be a little more over prepared, rather than underprepared.”
As unpredictable as the weather can be at times, its impact is everywhere — from the landscapes we enjoy to the challenges that extreme weather conditions can bring. This is where meteorology plays a vital role in helping us navigate the balance between nature’s beauty and its unbeatable power.
“A good weather forecast always starts with understanding what the weather is doing right now,” says Knight.
Meteorologists use tools like satellites to track cloud coverage and weather radar maps to identify the type of magnitude and intensity of precipitation falling at any given location. They also have weather stations, often located at airports, to measure temperature, pressure and humidity.
With this equipment, facilities and data obtained, Knight says, “Observations get set into complex computer models. This allows us to take the initial conditions and put them into complex physics equations and run them out from a few hours to a few weeks and see how the precipitation, temperature, and overall weather will evolve over that period of time.”
Understanding the science of weather forecasting isn’t just about predicting the day ahead. Rather, it’s about preparing for the future, protecting communities and embracing the ever changing forces of nature.
With insights from experts like Knight, we see how meteorology shapes our world, one forecast at a time.
“Weather to me is something that is a fundamental and intrinsic part of everyone’s everyday experience,” says Knight.
