What is an uphill airflow?

Uphill airflow, also known as orographic lift, occurs when air moves upwards over a mountain or elevated terrain. As the air rises, it cools and expands, which can lead to condensation and precipitation. This phenomenon is important in weather patterns, as it often results in increased rainfall on the windward side of mountains while creating drier conditions on the leeward side. It plays a significant role in shaping local climates and ecosystems.
