In this paper we explore the possibility of deriving\ud low-dimensional models of the dynamics of the Martian\ud atmosphere. The analysis consists of a Proper\ud Orthogonal Decomposition (POD) of the atmospheric\ud streamfunction after first decomposing the vertical\ud structure with a set of eigenmodes. The vertical\ud modes were obtained from the quasi-geostrophic vertical\ud structure equation. The empirical orthogonal functions\ud (EOFs) were optimized to represent the atmospheric\ud total energy. The total energy was used as the\ud criterion to retain those modes with large energy content\ud and discard the rest. The principal components\ud (PCs) were analysed by means of Fourier analysis, so\ud that the dominant frequencies could be identified. It\ud was possible to observe the strong influence of the diurnal\ud cycle and to identify the motion and vacillation\ud of baroclinic waves.
