Final answer:
A nor'easter occurs when northeast winds linked to a low-pressure system draw maritime Polar air into the northeastern U.S., leading to strong winds and heavy precipitation.
Step-by-step explanation:
A nor'easter typically occurs when: a. NE winds associated with a low-pressure system draw mP air into the northeastern United States.
This type of storm system is characterized by strong winds and heavy rains, where air flows toward the region of low pressure, causing a counterclockwise circulation at the surface in the Northern Hemisphere due to the Coriolis force. Nor'easters are notorious for their potential to cause severe weather, including heavy snowfall, rain, and strong winds, impacting the northeastern parts of the United States.
