dc.description.abstract | Ocean oscillations interact across large regions; these interactions may explain cycles in global temperature anomaly, including hiatus periods. Here, we examine interaction measures and compare results from model simulations to observations for El Niño and the Pacific decadal oscillation (PDO). We use the global climate model of the Met Office Hadley Centre. A relatively novel method for identifying running leading –lagging LL- relations show that the observed El Niño generally leads the observed PDO and this pattern is strengthened in the simulations. However, LL- pattern in both observations and models shows that there are three periods, around 1910-20, around 1960 and around 2000 where El Niño lags PDO, or the leading signature is weak. These periods correspond to hiatus periods in global warming. The power spectral density analysis, (PSD), identifies various ocean cycle lengths in El Niño and PDO, but the LL- algorithm picks out common cycles of 7-8 and 24 years that shows leading – lagging relations between them | en |
