A Monte Carlo simulation is used in order to study the effects of wave-particle interactions (WPI) on H+ distributions in the polar wind outflow. The simulation also considers effects of the gravity, the polarization electric field, the divergence of geomagnetic field lines and H+-O+ Coulomb collisions. The proton velocity distribution function (VDF) and the profiles of its moments (density, bulk velocity, parallel and perpendicular temperatures, heat flux…) are found for different levels of WPI, i.e., for different values of the normalized diffusion rate in the velocity space ( D ⊥). We find that the wave-particle interactions accelerate the polar wind and can have important effects on the double-hump H+ distribution obtained in the transition region between the collision-dominated low altitudes and the collisionless high altitude regions.
