Nor'easters thrive on the extreme temperature contrast between two air masses.
This temperature gradient creates instability, fueling a low-pressure center that intensifies as it moves toward New England and the Canadian Maritimes. 3. Nor'easter
Some nor'easters undergo "bombogenesis" (becoming a " bomb cyclone "), where pressure drops at least 24 millibars in 24 hours, leading to rapid intensification. Core Characteristics What Is a Nor'easter? | NESDIS - NOAA providing additional energy to the system.
