    "abstract": "In this work, we study the mean tropopause structure from the NCEP-NCAR\nreanalysis in the framework of a theory of baroclinic adjustment, focusing on\nthe impact of baroclinic eddies on the mean tropopause height. In order to\nmeasure the effects of such perturbations, we introduce an appropriate global\nindex that selects events of high baroclinic activity and allows us to\nindividuate the phases of growth and decay of baroclinic waves. We then\ncomposite the tropopause mean structure before and after a baroclinic event,\nfinding that baroclinic disturbances cause the zonally averaged midlatitude\nwinter tropopause height to rise. Our results suggest that the baroclinic\nadjustment processes should be taken into account to explain the nature of the\nmidlatitude tropopause.",
