Question

the type of rainfall caused when moist air is forced to ascend a mountain barrier ​

Answer 1

Answer:

When mountains of uplands act as barriers to air flow, forcing the air to ascend, moist air moving upslope cools adiabatically, producing clouds and precipitation.

Answer 2

Answer:

Orographic precipitation, rain, snow, or other precipitation is generated when moist air is lifted as it travels through the mountains.

Explanation:

The high mountains act as airflow barriers, forcing the air to rise, adiabatically cooling the moist air moving upwards, creating clouds and precipitation. Showers and thunderstorms usually occur when the air is unstable. But when it is stable, precipitation is more common and stable. Clouds and precipitation are concentrated on the windward side of the mountain and highland slopes. Topographical precipitation is the amount of precipitation produced by the forced upward movement of air during encounters in physiographic highlands.
