RIDGE LIFT

"Ridge lift" is the term used to describe when wind blowing against a cliff or hill is forced to rise. The updraft associated with this situation will offset some or all of the gliders rate of descent and if the updraft is stronger than the gliders natural descent rate, the glider will actually gain height. Low, steep coastal cliffs are famous for this effect but anytime that a steady wind blows directly against a wide slope, ridge lift will likely be created.
