密苏里州堪萨斯城的严重当地风暴预报中心假设使用的是较低3000英尺的平均温度。)这个位温与平均混合比的交集决定了低层中平均云团的凝结程度。沿着潮湿的绝热空气穿过提升的冷凝层，包裹继续向上到达500mb的水平。包裹温度和500毫巴级别的观测温度之间的代数差定义了SELS中心使用的提升指数。(请参见
Severe Local Storms Forecast Center, Kansas City, Missouri assumed, the mean temperature of the lower 3000 feet is used.) The intersection of this potential temperature with the mean mixing ratio determines the condensation level for a mean parcel in the lower layer. Following along a moist adiabat through the lifted condensation level, the parcel is continued upward to the 500 mb level. The algebraic difference between the parcel temperature and the observed temperature at the 500 mb level defines the Lifted Index as used by the SELS Center.(See
