摘要：

We analyze the effect of the 27-day solar cycle on characteristics of large-scale zonal wave harmonics of the geopotential in the northern hemisphere as simulated by the three-dimensional chemical-climatic model HAMMONIA. We found a noticeable correlation of the amplitude of winter planetary wave components in the northern hemisphere with the 27-day solar cycle. The strongest response is obtained for perturbations with wave number 1 in the middle and high latitudes. The amplitude of the corresponding variations of the geopotential height is similar to 300 m in the middle and upper stratosphere. The results presented point at possibility of the 27-day solar cycle effects on the large-scale wave activity in the winter atmosphere in the middle and polar latitudes of the northern hemisphere.
