Temperature Advection from Cloud Observations

Cold-Air Advection

• These cloud observations indicate that the winds are backing (turning counter-clockwise with height)

• a backing wind profile indicates cold-air advection - which will stabilize the atmosphere

• Cold-air advection and also be seen in satellite imagery....

QUESTION FOR THOUGHT:

Describe with the aid of a diagram the movement of low and mid-level clouds for:

• cold-air advection
• warm-air advection
