A theory of turbulent temperature fluctuations in the framework of Ext
ended Irreversible Thermodynamics is presented. In particular, we deri
ve an expression for the probability density function of temperature d
ifferences between two times. This expression modifies the result of C
hing (Phys, Rev. Lett, 70 (1993) 283) for very short time separations.
This modification can be, in principle, tested experimentally. (C) 19
