Abstract
A discrete-time stochastic process model for the streamwise component of the fluid velocity vector in turbulence is proposed and compared to data. The stochastic processes considered are sums of independent aut oregressions having particular distributional properties. The model si multaneously describes important time-domain and frequency-domain aspe cts of turbulence, in particular the distribution of the instantaneous value of the velocity and Kolmogorov's 5/3-law. A continuous-time mod el with similar properties is briefly discussed.
