Air Masses

Question 1

When an air mass moves over a warm area, what happens to the :temp, stability and RH
When an air mass moves over a cold area, what happens to the :temp, stability and RH

Answer 1

Warm: becomes warmer, unstable and RH decreases
Cold: becomes colder, more stable and RH increases

Question 2

How are the following conditions in stable vs unstable air masses
1-vis, 2-cloud, 3-precip, 4-wind, 5-flying conditions

Answer 2

Stable: 1-poor, 2-stratiform, 3-steady rain/drizzle, 4-steady, light, 5-smooth
Unstable: 1-good, 2-Cu, 3-showers, 4-gusty, 5-turbulent
