简介
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 change in the frequency and intensity of Atlantic hurricanes on multi‐decadal time scales. Given the short instrumental data records (about a century long) the central question is whether these climate fluctuations are robustly linked with the AMV and to what extent are these connections subject to changes in a changing climate. Here we address this issue by using the CMIP3 simulations for the 20th, 21st, and pre‐industrial eras with 23 IPCC models. While models tend to produce AMV of shorter time scales and less periodic …
