A substantial portion is associated with the North Atlantic … 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,
WebAccurate representation of the Atlantic Meridional Overturning Circulation (AMOC) in global climate models is crucial for reliable future climate predictions and projections. In this … WebVariations in the intensity and position of the North Atlantic jet stream (NAJ)—currents of strong prevailing westerly winds situated over the midlatitudes—play a critical role in modulating North American and European weather and climate, transport, commerce, and ecosystems (1–3).The NAJ arises principally as a consequence of equator-to-pole …
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 ...
