A comparison has been made, in as consistent a manner as possible, of a transport (bi‐Maxwellian based 16‐moment equations) and a semikinetic description of the terrestrial polar wind. The comparison shows a remarkably close agreement in the corresponding predictions for the altitude variation of the density, drift velocity, parallel and perpendicular (to B ) temperatures, and the flow of parallel and perpendicular thermal energies. This close agreement provides further evidence that the bi‐Maxwellian based transport equations are a powerful tool for studying thermal space plasmas that develop non‐Maxwellian features.
