How do winter storms form?
a)
from the clash of two air masses of different temperatures and moisture levels
b)
when an air mass of warm, moist, Canadian air moves west and interacts with a warm, moist air mass moving north from the Gulf of Mexico.
c)
when water vapor undergoes deposition,
12.
What three things are needed to have a blizzard?
