Initial 3-D neutral polar wind Original Research Article

The high-latitude polar-cap region is a highly dynamic region with many interesting phenomena associated with it, including the ion and neutral polar winds, plasma patches, polar holes, etc. To elucidate these phenomena and the neutrals produced via charge exchange associated with them, a new 3-D high-latitude hydrodynamic model of the polar-cap region has been developed. The model solves for H+, O+, Hs, Os, and electrons taking into account the effects of precipitating auroral electrons and convection electric fields. The first results of the model show a highly complex system at high-latitudes, with neutral stream particles flowing in all directions due to the combined effects of charge exchange and plasma convection.
