7.8.6. CAPEConvective Available Potential Energy (CAPE): CAPE is an indicator, in addition to Lifted Index, of atmospheric instability, which makes it very valuable in predicting severe weather. The higher the CAPE value the greater the instability. Data is presented in terms of joules/kg. Very severe weather events have been associated with CAPE values of several thousand joules/kg. In general, high values would be associated with low Lifted Index values.
