Web25 de out. de 2024 · The Atlantic multidecadal oscillation (AMO) is a large-scale climate signal, characterized by sea surface temperature (SST) anomalies sustained in the North Atlantic with a long periodicity of 50–70 years, which plays an important role in the NH climate [22,23,24,25]. In addition, the AMO can affect ENSO decadal variability . Web22.1.3 Atlantic multidecadal oscillation. AMO is SST changes in the North Atlantic Ocean from 0° to 70° N with multidecadal variability ( Dijkstra et al. 2006; Dai et al. 2004 ). In general, AMO has 65–70 years cycle with a 0.4°C range between extremes ( Schlesinger and Ramankutty, 1994; Enfield et al., 2001 ). how is a flat screen tv measured
