Ridge lift is a type of orographic lift that occurs when wind flows over a topographical feature, such as a ridge or hill. This lift is highly dependent on the characteristics of the wind, including its strength and direction. When wind encounters a ridge, it is forced upwards, creating lift due to the downward pressure on the leeward side.

If there are changes in wind strength, stronger winds will generate more pronounced ridge lift, while weaker winds may not produce sufficient lift for effective soaring. Similarly, a change in wind direction can also significantly affect how effectively the lift is generated. For example, if the wind shifts to a more favorable angle relative to the ridge, it can enhance the lift, whereas an unfavorable angle may diminish lift or even create sink.

Understanding these concepts is critical for pilots, as they need to assess weather conditions and anticipate how changes in wind can affect their flying performance and safety while utilizing ridge lift.
