We present 12CO and 13CO J=2-1 large scale maps of Orion A observed with the IRAM 30-m radiotelescope. The size of the maps is 1x0.8 deg^2 at its largest extent, and their angular and velocity resolutions (11" and about 0.4 km/s, respectively) are higher than those used in previous extended CO maps of Orion. Besides a very complex velocity structure, these maps show numerous filaments and gas condensations, cometary globules and cavities (or tunnels). All these are signatures of the feedback action of massive star formation on the preexisting molecular gas. Among them, the detection of periodic structures on the surface of an elongated molecular cloud, provide evidence of the development of hydrodynamical instabilities shaping the molecular cloud. The discovery of these ``waves'' shows the high angular and spectral resolution required to understand star formation processes.
