Sažetak

The paper analyses the thermodynamical aspect of the terms CAPE and TCAPE, defined in the standard way according to Brunt (1941) and in another way in Renno and Ingersol’s paper (1996). Based on this, in this paper it is pointed out that the thermodynamical foundations for the difference existing between the two definitions. The analyses itself is based on the presentation of all the relevant terms in thermodynamics diagrams and relations for in­ter­nal-equilibrium processes and processes with internal friction.

The paper shows the internal friction which Renno and Ingersol take into consideration and make their definition of CAPE and TCAPE different from the standard one and not equivalent to it. In this connection, only ac­cording to the standard definition CAPE and TCAPE represent the maxi­mum work which is real in advance calculable measure of convective circulation intensity.
