This paper demonstrates the existence of intermittent turbulence in the solar wind at 8.5 AU. The pth-order velocity structure functions show scaling behavior in the range of periods from 0.85 hour to 13.6 hours for p≤20. The exponent of the scaling law s(p) is a quadratic function of p. Our observations of s (p) for compressible MHD turbulence on a scale of the order of ~1 AU=1.5¿108 km are consistent with laboratory measurements of s(p) for gasdynamic turbulence on a scale of the order of 1 m, indicating the universal character of intermittent turbulence. The observations are not described by the ''constant &bgr;'' model of intermittent turbulence. They are marginally consistent with the lognormal model. The observations are consistent with a random &bgr; model prediction which assumes that the turbulence is a mixture of sheets and space-filling eddies. ¿American Geophysical Union 1991 |
