Description:
Rossby wave propagation is one of the most important mechanisms for teleconnections between regions. This propagation relies on the meridional gradient of vorticity, which gets progressively weaker at higher latitudes. Despite this, we show that Rossby waves do have a role to play in high latitude variability, albeit a weaker one than at lower latitudes. In this presentation we outline two teleconnection pathways: 1) how waves propagating from lower latitudes behave as they reach the polar regions; 2) how waves can be triggered at high latitudes by anomalous surface heating and then propagate equatorward.
