Cohen's real-time winter forecast for Europe for 2003-04, was also more accurate than those issued using conventional models.
"I think before my research, the mainstream, or most of the people, felt winter weather kind of just happened," Cohen says. "It just happened spontaneously, randomly, and had these large-scale shifts, these large-scale patterns that happened really abruptly and without any kind of warning. But I felt differently about climate, particularly winter climate, about how it works.That it's something that evolves over time.
"You can actually follow what's going on," he says. "It's not just some random or haphazard change."
Cohen says he'd next like to discover the factors that contribute to Siberian snowfall, so he can tell us even sooner if we have to break out the snow shovels or the sun screen.
