Disagreement in the regional trends between the GRACE processing centres is most noticeably in areas south of Greenland, and in the southeast and northwest Pacific Ocean.
I also think solar effects are probably regional and mostly over the ocean, filtered through enso and other ocean processes.
GEOTRACES will be global in scope, consisting of ocean sections complemented by regional process studies.
The two - day FAMOS workshop will include sessions on 2017 sea ice highlights and sea ice / ocean predictions, reports of working groups conducting collaborative projects, large - scale arctic climate modeling (ice - ocean, regional coupled, global coupled), small (eddies) and very small (mixing) processes and their representation and / or parameterization in models, and new hypotheses, data sets, intriguing findings, proposals for new experiments and plans for 2018 FAMOS special volume of publications.
Expand the use of eddy - resolving models, particularly in regional / process studies designed to: i) test the robustness of AMOC variability mechanisms identified in coarser GCMs or idealized models; ii) address the origins of persistent model bias in the North Atlantic region (e.g., Gulf Stream separation and the North Atlantic Current path); and iii) assess the role of ocean turbulence in AMOC variability.

Furthermore, by homogenizing the entire ocean into a single metric, they miss important nuances of local and regional scale redox changes that might reflect the activity of climatic feedback processes, such as weathering, ocean circulation change, or temperature change.
Although the science of regional climate projections has progressed significantly since last IPCC report, slight displacement in circulation characteristics, systematic errors in energy / moisture transport, coarse representation of ocean currents / processes, crude parameterisation of sub-grid - and land surface processes, and overly simplified topography used in present - day climate models, make accurate and detailed analysis difficult.
