摘要：
The probability density function (PDF) and spatial statistics of both the energy dissipation rate epsilon and the temperature structure constant C-T(2) are determined for the shear region of a nocturnal jet. The PDF of epsilon and C-T(2) are approximately lognormal. In addition, the joint probability density function of epsilon and C-T(2) is approximately a joint lognormal distribution. The one-dimensional spatial spectra of epsilon and C-T(2) in the inertial region have a k(-0.5) and k(-0.6) dependence, respectively, where k is the horizontal spatial wavenumber.
