N2 - The statistical method developed in the first part of the paper is applied to obtain parameters of internal gravity wave (IGW) harmonics with periods from 5 min to 6 hours propagating upward and downward, and in the direction of the mean wind and opposite to it, from the observations of motions in the middle atmosphere with the middle and upper atmosphere radar. Usually, wave amplitudes and modulus of momentum fluxes are larger for IGWs having upward energy fluxes and propagated opposite to the mean wind (eastward propagation in summer and westward propagation in winter). Most of IGWs have momentum fluxes directed to the northeast in winter and to the east in summer.
