Meridional Energy Transport, both in the ocean (OMET) and atmosphere (AMET), is one of the key aspects for the climate system. This study focuses on the AMET & OMET from mid-latitudes to the Arctic. The quantification of AMET & OMET is based on the reanalysis products, which include ERA-Interim, MERRA2, JRA55 for the atmosphere and ORAS4, GLORYS2V3, SODA3 for the ocean. The mean heat transports in all datasets agree well, whereas the spatial distribution and temporal variation of AMET & OMET, deviate substantially. This results in a large difference in the low frequency variability of AMET & OMET at certain latitudes. Only after 2010 multiannual variations in the reanalysis products agree well. The results show that the decline of sea ice has a close relation with the change of AMET & OMET. This relation also indicates the interaction between ocean and atmosphere at certain latitudes. : Presentation given at EGU 2018 in Vienna on April 9th 2018 during the session 'Arctic Climate Change: governing mechanisms and global implications'.
