Temperature fluctuations in a turbulent shear flow are modeled by a ramp-like signal on which relatively high frequency Gaussian fluctuations are superimposed. Both linear ramps with fixed height and length and exponential ramps of variable length are considered. Parameters which characterize the exponential ramps are obtained from experimental data in a heated jet. High order moments of temperature calculated with the use of the ramp model are in reasonable agreement with available experimental measurements.
