Final answer:
The three types of clouds that may form in a mountain wave condition are lenticular, rotor, and cap.
Step-by-step explanation:
The three types of clouds that may form in a mountain wave condition are: Lenticular, rotor, and cap.
Lenticular clouds are lens-shaped clouds that often form near mountains and indicate the presence of waves in the atmosphere. Rotor clouds are turbulent, low-level clouds that can form on the downwind side of mountains due to the interaction between the airflow and the terrain. Cap clouds are stationary clouds that form at the top of mountain waves and can signify the presence of a strong atmospheric inversion.
