Description

Mountains from the tropics to the polar zones have undergone obvious environmental changes for many decades, most notably by receding glaciers. Knowledge of the physical mechanisms, which transmit large-scale climate change to these “cold regions”, remains nonetheless unsatisfying. In particular, how mesoscale processes act as a bridge in both directions, on the one hand to the large-scale climate dynamics and, on the other, to local surface-layer dynamics, is still an understudied area of research. In this session we address such multi-scale linkages for mountain ranges worldwide, and bring together dynamical meteorology/climatology and cryospheric sciences. Possible mechanisms at different scales could be climate-mode driven flows, insolation-driven diurnal circulations, atmospheric rivers, or katabatic winds. High-resolution dynamical modeling, observations, detection and attribution, or machine-learning approaches can all be considered to identify the physical linkages. They will ultimately help to project climate change in cold regions on a stronger process-oriented basis.
