Description

The response of a Hemispheric model atmosphere to forcing by the Hemispheric topography and the stationary heat sources in winter was examined. In this computation the model described in Part I of this paper is used.<br>The computed results show that the amplitude of standing wave responding to forcing by stationary heat sources at high latitudes, for zonal wave number 1, is larger than that forced by stationary heat sources at middle latitudes. The results also show that the amplitude of standing waves for zonal wave number 1 responding to forcing by the Hemispheric stationary heat sources is larger than that responding to forcing by the Hemispheric topography. In these computations, the role of refractive index square of standing waves for zonal wave number 1 or 2 is discussed in relation with the propagation of standing waves from the lower troposphere at middle and high latitudes toward the upper stratosphere at high latitudes or the upper troposphere at low latitudes.<br>The momentum, heat and Eliassen-Palm fluxes due to standing waves computed by this model, are qualitatively in good agreement with the observed results.
