Robust features of Atlantic multi‐decadal variability and its climate impacts
[1] Atlantic Multi‐decadal Variability (AMV), also known as the Atlantic Multi‐decadal Oscillation (AMO), is characterized by a sharp rise and fall of the North Atlantic basin‐wide sea surface temperatures (SST) on multi‐decadal time scales. Widespread consequences of these rapid temperature swings were noted in many previous studies. Among these are the drying of Sahel in the 1960–70s and chan...
متن کاملObserved Decadal Midlatitude and Tropical Atlantic Climate Variability
Two common indicators of Atlantic climate variability, viz., the North Atlantic oscillation (NAO) and the crossintertropical convergence zone (ITCZ) sea surface temperature (SST) gradient, are examined for their frequency characteristics and midlatitude-tropical links. SST anomalies north and south of the ITCZ are found to be uncorrelated on all time scales, while the sea level pressure (SLP) f...
متن کاملRecent Progress in Understanding and Predicting Atlantic Decadal Climate Variability
Purpose of Review Recent Atlantic climate prediction studies are an exciting new contribution to an extensive body of research on Atlantic decadal variability and predictability that has long emphasized the unique role of the Atlantic Ocean in modulating the surface climate. We present a survey of the foundations and frontiers in our understanding of Atlantic variability mechanisms, the role of...
متن کاملA simple coupled model of tropical Atlantic decadal climate variability
[1] A linear, zonally averaged model of the interaction between the tropical Atlantic (TA) atmosphere and ocean is presented. A balance between evaporation and meridional heat advection in the mixed layer determines the sea surface temperature tendency. The atmosphere is a fixeddepth, sub-cloud layer in which the specific humidity anomaly is determined by a steady-state balance between evaporat...
متن کاملSolar forcing synchronizes decadal North Atlantic climate variability
Quasi-decadal variability in solar irradiance has been suggested to exert a substantial effect on Earth's regional climate. In the North Atlantic sector, the 11-year solar signal has been proposed to project onto a pattern resembling the North Atlantic Oscillation (NAO), with a lag of a few years due to ocean-atmosphere interactions. The solar/NAO relationship is, however, highly misrepresented...
