英文摘要: The significant wave height (H s ) variability caused by wind anomalies associated with the co-occurrence of the Madden-Julian Oscillation (MJO) and El Niño–Southern Oscillation (ENSO) was investigated in the New Zealand region. For this purpose, H s and wind anomalies composites were created using 23 years (1979–2002) of modelled data during November–March periods, when simultaneous ENSO-MJO phase pairs are potentially most active. The results show striking features: El Niño-related wave conditions (which consist of increased H s along the west and south coasts of New Zealand) are reinforced during MJO phase 8, whereas the wave conditions associated with La Niña (which consist of larger H s along the north coast) are enhanced during MJO phase 6; Similar wave anomalies are generated during opposing ENSO phases (La Niña and El Niño) when these are combined with MJO phases 3 and 5, respectively; The majority of statistically significant H s anomalies disappear from the study area during El Niño-MJO phase 6, El Niño-MJO phase 2, and La Niña-MJO phase 4, showing the neutralizing nature of some phase combinations; Finally, negative H s anomalies are experienced off the country's west coast during El Niño-MJO phase 4, in contrast to the positive anomalies expected during El Niño events. These results clearly show the importance of remote forcing to wave anomalies in the New Zealand region, and highlight the need to assess atmospheric and oceanic conditions considering multiple climate oscillations. © 2018 Royal Meteorological Society
