本文在考虑大气旋转的情况下，导出了中尺度定常地形波的偏振关系，以及波能垂直总通量和水平速度振幅的垂直廓线计算公式。表达式推导出的总波热通量，平均流的加速度，和由MSOW产生的热通量。计算了多尺度驻波在大气中从地面到低热层的传播特性。结果表明，MSOW对中高层大气的环流和热力状况有明显的影响。
Polarization relations for mesoscale stationary orographic waves (MSOWs) and formulas for calculating vertical profiles of the total vertical flux of wave energy and amplitudes of horizontal speed are obtained by taking account the rotation of the atmosphere. Expressions are derived for the total wave heat flux, accelerations of the mean flow, and heat influxes generated by MSOWs. Calculations of the characteristics of MSOWs propagating in the atmosphere from the surface to the lower thermosphere are made. It was shown that MSOWs may significantly affect the circulation and thermal regime of the middle and upper atmosphere.
