Web[1] The North Atlantic Oscillation (NAO) has a profound effect on winter climate variability around the Atlantic basin. Strengthening of the NAO in recent decades has altered surface climate in these regions at a rate far in excess of global mean warming. However, only weak NAO trends are reproduced in climate simulations of the 20th Century, WebNorth Atlantic climate multidecadal variability using ob-servations (section 2a) and GCM results (section 2b). a.

Web6 de dez. de 2024 · In the North Atlantic, the most extreme winds occurred in the border of the horse latitudes in February in the 1980s and in December in the 1990s. A key finding, however, is that the decadal EWF variability in the central North Atlantic is rather small compared to the variations over Europe (Figure 10). WebAs a result, the AMM (and other Meridional Modes) represent an important pathway by which random atmospheric variability in the extratropics can teleconnect into the deep tropics and influence climate. In particular, warm tropical North Atlantic SSTs associated with an AMM event can anchor the seasonally migrating Intertropical Convergence Zone ...
