Random velocity fields, Gaussian, Fourier modes, passive trace transport.Abstract
This work presents a general form for a scalar random field which is written as a sum of finitely many Fourier modes. We get some of its statistical proprieties and analyze its geometry. Additionally, we derive a model for a Gaussian, two dimensional, mean-zero, homogeneous, steady, and incompressible random velocity field and provide numerical evidence about the non-normality of the joint distribution of the Lagrangian velocity process.
