Phys. Rev. Lett. 73, 959–962 (1994)Intermittency in fully developed turbulence: Log-Poisson statistics and generalized scale covarianceReceived 3 March 1994; published in the issue dated 15 August 1994 Some properties of a model of intermittency in fully developed turbulence due to She and Lévêque [Phys. Rev. Lett. 72, 336 (1994)] are explored. The probability functions solution of the model is shown to be simply related to the log-Poisson statistics of local nondimensional energy dissipation. It is also shown that the intermittency obtained by She and Lévêque can be interpreted as the consequence of the scale covariance of the energy dissipation. Based on these observations, a new picture of turbulence is presented, in which scale covariance plays a central role. © 1994 The American Physical Society URL:
