Verified step by step guidance

Understand the concept of orographic lift: When moist air is forced to ascend over a mountain, it undergoes a process called orographic lift. As the air rises, it expands and cools due to the decrease in atmospheric pressure at higher altitudes.

Recognize the cooling effect: As the air cools, its capacity to hold moisture decreases, leading to condensation. This process forms clouds and can result in precipitation on the windward side of the mountain.

Consider the formation of a rain shadow: After the air has lost much of its moisture on the windward side, it descends on the leeward side of the mountain. Descending air warms and becomes drier, creating a rain shadow effect where there is significantly less precipitation.

Evaluate the changes in air pressure: While the air pressure does change as the air moves over the mountain, the most significant effect is the cooling and precipitation on the windward side, not a significant increase in air pressure.

Conclude with the most likely outcome: Given the process of orographic lift and the cooling effect, the most likely outcome is that the air cools and precipitation occurs on the windward side of the mountain.
