Which option is NOT a type of Local Wind?

• A. Frontal winds
• B. Slope Winds
• C. Valley Winds
• D. Sea/Land Breezes

Answer: (A)

Local winds are the patterns created by local heating and terrain effects. Slope winds develop when sun-heated slopes cause upslope flow during the day and cooler air drains downslope at night. Valley winds move air along valleys and can be driven by diurnal heating differences. Sea/land breezes arise from the temperature contrast between land and sea, producing a daytime marine breeze and a possible nighttime reversal. Frontal winds come from weather fronts—the boundary between air masses—and are governed by larger-scale weather systems rather than local terrain or daily heating. Because they’re driven by synoptic-scale fronts rather than local terrain effects, frontal winds are not considered a Local Wind.
