Observing the movement of clouds can provide insight into the wind's what at that level?

• A. direction and speed
• B. temperature and humidity
• C. altitude and pressure
• D. density and moisture

Answer: (A)

Clouds drift with the air they’re in, so watching their motion tells you the wind’s direction and speed at that height. If you see a line of clouds moving toward a particular direction, that shows where the air is flowing. By noting how far the clouds travel over a minute or two, you get a sense of the wind’s speed at that level. Temperature and humidity influence whether clouds form and what type they are, not how they move. Altitude and pressure describe the environment, but cloud drift itself isn’t a direct read on those values. Density and moisture describe air mass properties and likewise don’t directly reveal wind movement.
