Most Unstable CAPE (J/kg) & LPL Height (m AGL)

MUCAPE (Most Unstable Convective Available Potential Energy) is a measure of instability in the troposphere. This value represents the total amount of potential energy available to the most unstable parcel of air found within the lowest 300-mb of the atmosphere while being lifted to its level of free convection (LFC). No parcel entrainment is considered. The CAPE and CIN calculations use the virtual temperature correction.

The LPL (Lifted Parcel Level) allows for the determination of the height of the most unstable parcel. This makes it easy to identify areas where the largest CAPE is "elevated."
