Wind measures what in an atmosphere?

Wind measures what in an atmosphere?

• A. Lateral movement within an atmosphere
• B. Vertical movement
• C. Humidity changes
• D. Temperature changes

Answer: (A)

Wind is the horizontal movement of air across the surface. It describes how air travels sideways from one area to another, which is why measuring wind tells you about lateral transport that affects things like fire spread and ember transport. Vertical movement—updrafts and downdrafts—drives convection and cloud formation, but that’s not what wind itself is. Humidity changes and temperature changes describe the air’s state, not its motion, though they can influence wind patterns.
