Research affiliate Judah Cohen speaks with WGBH’s Edgar B. Herwick III about what distinguishes a Nor’easter, an extratropical cyclone powered by "strong differences in temperature," from other storms. As cold air from the Arctic meets warm water and air from the Gulf of Mexico, it creates “a very large temperature differential over a relatively short distance,” says Cohen. “And that temperature differential gives you the energy for these storms.”
