Phys. Rev. Lett. 70, 283–286 (1993)Probability densities of turbulent temperature fluctuationsReceived 24 August 1992; published in the issue dated 18 January 1993 Starting from an assumption of universality in turbulence and building upon the work in Y. G. Sinai and V. Yakhot, Phys. Rev. Lett. 63, 1962 (1989), we construct a closed-form expression for the probability density function of temperature fluctuations. This result is found to be in good correspondence to experimental data obtained at Chicago and Yale. By extending this method, we obtain a similar expression for the probability density function of temperature differences between two times. Again the result is checked to hold very well, except for very short time separations. © 1993 The American Physical Society URL:
