CAPE (1)
- Usado para
- convective available potential energy
- Definição1
- A measure of the amount of energy available for convection. CAPE is directly related to the maximum potential vertical speed within an updraft; thus, higher values indicate greater potential for severe weather. Observed values in thunderstorm environments often may exceed 1,000 joules per kilogram (j/kg), and in extreme cases may exceed 5,000 j/kg. However, as with other indices or indicators, there are not threshold values above which severe weather becomes imminent.

- Nota adicional1
- The CAPE values can differ slightly depending on which NWP model-derived soundings it was calculated with, but the graphical ‘equal area’ properties of the tephigram allow very meaningful constructions to determine convective depth.
