An analysis of Ulysses plasma and magnetic field data from the high southern latitude pass revealed that at large spatial scales corresponding to wave frequencies below 10-5 Hz in the spacecraft frame, there is a transition from highly Alfv¿nic turbulence in all three spatial components of the fields to fluctuations which are Alfv¿nic only in field components transverse to the radial direction with uncorrelated radial magnetic and velocity fields. We find that the general properties of the turbulence can be simulated using a spectral method solution of the magnetohydrodynamic (MHD) equations only when certain types of initial conditions are employed. These simulations place constraints on conditions in the solar atmosphere that can generate the observed fluctuations. ¿ American Geophysical Union 1995
