Chapter 4 - Atmospheric Lifting Mechanism, Cold Front, and Warm Front

Question 1

What are the atmospheric lifting mechanisms?

Answer 1

orographic lifting (air is lifted over an obstacle)

frontal lifting (a cold air mass pushes a warmer one upward)

convergence (two air masses collide and air in between is forced upward)

convective lifting (air heats up and rises over hot spots)

Question 2

How do cold fronts move?

Answer 2

The cold air moves into warm surfaces winds. This cause the warm air to be lifted.
(Basically active cold air masses moves towards warm air masses)

Question 3

How do warm fronts move?

Answer 3

Warm air masses (stable conditions) get gentle lifting by passive cool air masses, slowly raising over the cool air masses
