Some numerical experiments of the geostrophic adaptation process of subsynoptic scale system have been carried out by using a symmetrical five-level PE-model in cylindrical coordinates. The effect of heat sources is especially discussed. The numerical results are in good agreement with the previous analytic results obtained by linear and nonlinear theory. In the linear adaptation process steady heat sources increase the amplitude of gravity-inertia wave and the system is adapted to steady heat sources eventually....

Based on the complete dynamical equations of the moist atmospheric motion, the qualitative theory of nonlinear atmosphere with dissipation and external forcing and its applications are systematically discussed by new theories and methods on the infinite dimensional dynamical system. The complete nonlinear dynamical equations of the moist atmospheric motion with dissipation and external forcing are rewritten as an equivalent operator equation in Hilbert space, and the properties of operators and their physical senses are studied. On the basis of the above, the existence of global attractor of the moist atmospheric system is proved, and the characteristic of nonlinear adjustment to external forcing is revealed. Furthermore, the results mentioned above are extended to the cases with orographic dynamical effect and non-stationary external forcing. Meanwhile, the existence of the inertial manifold of the atmospheric equations is investigated. On the basis of theoretical results, this paper presents three classes of time boundary layers existed in the forced dissipative nonlinear system, the principle of simplification of atmospheric equations, the principle of operator restriction of splitting algorithm and the constructive method of a few freedoms to support the base of attractor. Besides, the applications of the theoretical results to the design of difference schemes, the computational stability analysis of nonlinear evolutionary equations, the numerical analysis of atmospheric multiple equilibria, the improvement of extended forecast of numerical models and the short-term climate forecast, the analysis and prediction of one class of mesoscale system are discussed; the necessary conditions possessed in the dynamic models describing the long-time process are pointed out; and a rational explanation of the harmonization of initial values with model is given. Finally, the studied trends in future are prospected.
