| Summary: | <!--!introduction!--> Atmospheric circulation transports moist static energy from the mid-latitudes to the Arctic as compensation for radiative imbalances between Arctic and lower latitudes. Variations in sea ice cover, ocean temperature and atmospheric conditions can potentially modulate these moist static energy transports. We compare the transports of atmospheric energy in total as well as its components between an early and a late period of Arctic amplification. In particular, we analyze the dependence of the transport changes on region, height and season in reanalysis data. A barotropic wind field correction is applied before the calculations of the atmospheric energy transport accounting for inconsistencies in mass-fluxes due to the assimilation process. An increased meridional energy transport during summer is mostly compensated by a decrease in late winter. The changes in the dry static and latent components of the energy transport differ between individual months. In the vertical, changes in ... : The 28th IUGG General Assembly (IUGG2023) (Berlin 2023) ... |
