Which of the following is listed as a type of local wind?

• A. Slope Winds
• B. Thunderstorm Winds
• C. Frontal Winds
• D. Whirlwinds

Answer: (A)

Local winds are winds produced by the local terrain and the day-night heating cycle, not by large-scale weather systems. Slope winds arise from differential heating on mountain slopes: during the day, the slopes warm and air rises upslope, drawing air from the valley up the slope; at night, the slopes cool and cooler air drains downslope into the valley. This diurnal, topography-driven flow is a classic example of a local wind. The other options describe winds tied to storms or fronts (convective outflow, gust fronts, or synoptic-scale fronts) or very small, episodic phenomena like dust devils, which aren’t categorized as local winds in this context. So slope winds are the local-wind type in question.
