Abstract
We consider statistics of the passive scalar on distances much larger than the pumping scale. Such statistics is determined by statistics of Lagrangia n contraction, that is by probabilities of initially distant fluid particle s coming close. At the Batchelor limit of spatially smooth velocity, the br eakdown of scale invariance is established for scalar statistics. (C) 1999 American Institute of Physics. [S1070-6631(99)03008-1].
