Atmospheric dynamics in the mid-latitudes features quasi-stationary atmospheric states (QSAS), also denoted as atmospheric blocking. To obtain a better understanding of the stability of QSAS and to improve predictions of transitions into and out of QSAS, we aim at mathematically describing and analyzing them as persistent dynamic structures. In particular, we propose to confront geometric trajectory-based with set-oriented transfer-operator-based, Eulerian with Lagrangian, and model-based with data-based approaches.
