Lifted Index forecast for region 北歐 from model GFS. gfs-credit The lifted index is a stability index to help measure the buoyancy of the atmosphere. Atmospheric temperature generally decreases with height. When surface air rises, it also cools. However, sometimes it cools more slowly than its surounding environment. When this happens, the rising air is warmer and less dense, and the rising air can continue to rise, leading to storm development.
