Which term describes a warm upslope wind?

• A. Sea breeze
• B. Land breeze
• C. Anabatic wind
• D. Katabatic wind

Answer: (C)

Anabatic wind is the term for a warm upslope wind. It forms when solar heating makes the air along a mountainside rise as buoyant air moves upslope. Because the slope-heated air near the surface is warmer than the air higher up, it ascends the slope, creating a local, warm upslope flow. The opposite type, katabatic wind, is a downslope, typically cooler flow that drains air from higher ground. The sea breeze and land breeze are coastal phenomena driven by land-sea temperature differences and aren’t specifically about upslope movement, so they don’t describe this scenario.
