What are nor’easters? Describe how nor’easters differ from hurricanes
What will be an ideal response?
ANSWER: Nor'easters are extratropical cyclones that strike the northeastern parts of the United States. Named for the direction from which their winds come, nor'easters bring heavy rain and often heavy snowfall. They are most common from October through April, especially February (rather than late summer for hurricanes). They build at fronts where the horizontal temperature gradient is large and the air is unstable. They lack distinct, calm eyes and are not circular in form but can spread over much of the northeastern United States and eastern Canada. They are cold-core systems that do not lose energy with height. If jet stream winds move an air mass away from the center of a storm, this drops surface pressure and increases storm strength. Damage is concentrated along the coast, whereas much of the damage from hurricanes occurs farther inland. With strong winds from the northeast, they typically batter northeast-facing shorelines.
