North Atlantic Current

The North Atlantic Current is a warm water current that flows from the Caribbean to the British Isles, and its location can shift eastward due to changes in sea surface temperature advection and other factors. It is also affected by freshening of the North Atlantic due to Greenland ice sheet mass loss, which can impact the Gulf Stream and sea surface heights along the eastern seaboard.From: Artificial Intelligence and The Environmental Crisis [2019], Climate Change and the Coast [2019], Copernicus Marine Service Ocean State Report [2018]

Icing rate is lowest in the southwest due to higher air temperatures. This is only partly a result of the relatively high sea-surface temperature associated with the North Atlantic Current. However, the main reason is that these areas are located some distance away from the cold lands or sea ice, leading to the fact that the air has time to be sufficiently heated from below to avoid the high icing rates apparent in the other areas due to strong vertical mixing in weather situations in which icing occurs (Samuelsen and Graversen, 2017).

Not surprisingly, the western boundary focus area where these rather large errors are located, is also the area with the largest Rossby numbers, compared to the rest of the regional model domain. This area has strong currents, as it is the area where the Gulfstream turns into the North Atlantic Current. Considering the high Rossby numbers and the errors of GOFS in this same area, it is not unreasonable to assume that the errors in the regional model seen in Figure 2 may be due, at least in part, to errors at the boundaries. Note that the Rossby number shown in Figure 3 is computed as the Coriolis-normalized depth-averaged vertical vorticity in the upper 100 m from GOFS model outputs, for 14 June 2019.
