Which cloud type is not typically associated with mountain wave phenomena?

• A. Cumulus
• B. Stratus
• C. Thunder cells
• D. Lenticular

Answer: (C)

Mountain wave phenomena come from stable air flowing over mountains, creating vertically propagating gravity waves. As air rises and cools in the wave, lenticular clouds often form on the lee side, indicating the smooth, layered wave pattern. Strong shear can produce rotor clouds, and the lifting within the wave can generate cumulus or stratus in the right conditions. Thunderstorm cells, driven by deep convective instability, are not part of this wave-driven pattern; they indicate a different atmospheric process. So thunder cells are not typically associated with mountain wave phenomena.
