Analytical models for magnetic turbulence are an important ingredient in the theory of field line wandering and cosmic ray diffusion. In previous investigations, a so-called slab/2D model has been used. In the present article, we develop a more general analytical model for magnetic turbulence. This model is then compared with solar wind observations. We investigate numerically the possibility to explain the maltese cross structure of the correlation function of solar wind turbulence with this model.
