CAPE exists within the conditionally unstable layer of the troposphere, the free convective layer (FCL), where an ascending air parcel is warmer than the ambient air. CAPE is measured in joules per kilogram of air (J/kg). Any value greater than 0 J/kg indicates instability and an increasing possibility of thunderstorms and hail. Generic CAPE is calculated by integrating vertically the … WebWhen we talk about a highly unstable atmosphere, CAPE values are usually in excess of 2500 J/kg’s which would supply ample energy for strong updrafts and violent thunderstorms, should they develop.
