Where Water Goes, Snow Follows: MTU Research Scientist Develops Novel Approach to Lake-Effect Snow Forecasting
With breakthrough new technology that measures water isotopes on the move, researchers from Michigan Tech’s Great Lakes Research Center are driving, boating and snowmobiling around the Keweenaw Peninsula to help make lake-effect snow more predictable.
Ben Kopec is an assistant research scientist with the GLRC and an adjunct assistant professor in Tech’s Department of Civil, Environmental, and Geospatial Engineering. He's also an accomplished hydrologist. He studies water isotopes — unique signatures determined by the structure of water molecules that allow scientists to identify water vapor’s point of origin and follow it through the water cycle. This tracking process is known as water cycle tracing or isotope hydrology.
“When water evaporates from all sorts of different sources, the temperature of that water will dictate a unique signal that can be identified in isotopic measuring,” said Kopec. “These water isotopic tracers allow us to quantitatively measure how much water is moving through different parts of the water cycle, where the water is coming from and what conditions affect the different processes.”
Kopec’s research is ongoing, but he thinks knowing how much water is evaporating off of Lake Superior may be the key to accurately predicting snowfall events. Follow his research journey on Michigan Tech’s Unscripted Research Blog.
