North atlantic oscillation definition
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 ). WebNorth Atlantic Oscillation and the North Pacific Oscillation Same I•atures appear again when only reanalysis data used Ibr composite. This also agrees well with the results of Wallace and Hsu[1985, c.f. Figure 2]. Similarly, the AOI can also measure the states of the index cycle and represent the oscillation between the
