What typical climate phenomenon is associated with nor'easters?

Nor'easters are significant winter storm systems that typically bring severe winter weather, which is why the correct response involves severe winter storms. These storms develop along the East Coast of the United States and are characterized by strong winds, heavy snowfall, and sometimes coastal flooding, depending on the storm's intensity and location.

These systems often form when cold air from Canada collides with warm, moist air from the Atlantic Ocean, leading to heavy precipitation in the form of snow, especially in the northern and inland areas. The intensity and duration of nor'easters can result in blizzards, making travel hazardous and leading to power outages due to downed trees and power lines from the accumulation of snow and ice.

In contrast, heatwaves and droughts are associated with high pressure and prolonged periods of dry weather. Flooding can occur as a consequence of nor'easters, but it is a secondary effect rather than the defining characteristic of the storms themselves. Thus, the primary phenomenon associated with nor'easters is indeed severe winter storms, highlighted by their capacity to produce heavy snowfall and strong winds.
