导出了准地转湍流的两个三阶结构函数关系,一个是位熵正级联的结构函数关系,一个是能量逆级联的结构函数关系。这些关系与Kolmovorov(1941)关于三维湍流三阶纵向结构函数的四/五定律相对应。
We derive two third-order structure function relations for quasi-geostrophic turbulence, one for the forward cascade of potential enstrophy and one for the inverse cascade of energy. These relations are the counterparts of Kolmovorov's (1941) four-fifths law for the third-order longitudinal structure functions of three-dimensional turbulence.
