A simple self-consistent model of thermal diurnal tides in the earth's atmosphere is constructed which gives the possibility to separate annual and semi-annual prograde and retrograde components. For a realistic model of the Earth the numerical estimations of atmospheric excitation of out-of-phase nutational components are obtained. It is shown that prograde annual component may be totally explained by thermal atmospheric tides; at the same time, the influence of these tides on retrograde annual component is negligible small.
