Abstract

Jiang et al. (2023), https://doi.org/10.1029/2023gl103777 argue that the apparent impact of the equatorial Atlantic on El Niño-Southern Oscillation (ENSO) is a statistical artifact, and that the 6-month lead correlation reported in previous studies stems from early developing ENSO events driving the equatorial Atlantic zonal mode (AZM) in boreal summer and maturing in winter. Closer examination, however, reveals that most AZM events develop too early to be driven by developing ENSO, and that the influence of decaying ENSO events has to be considered too. Thus, while early developing ENSO events may play a role, they do not fully explain observed AZM behavior. Our aim is not to argue for or against an AZM influence on ENSO, but rather to show that Jiang et al.’s analysis is insufficient to resolve this issue. More analysis will be needed for a deeper understanding of Atlantic-Pacific interaction.

评冯江等（2023）《解决热带太平洋/大西洋相互作用难题》

Jiang等人（2023），https://doi.org/10.1029/2023gl103777认为赤道大西洋对厄尔尼诺Niño-Southern涛动（ENSO）的明显影响是一种统计伪象，先前研究中报道的6个月的领先相关性源于早期发展的ENSO事件在北方夏季驱动赤道大西洋纬向模态（AZM），并在冬季成熟。然而，更仔细的研究表明，大多数AZM事件发展得太早，不可能是由正在发展的ENSO驱动的，而且还必须考虑ENSO事件衰减的影响。因此，虽然早期发展的ENSO事件可能起作用，但它们并不能完全解释观察到的AZM行为。我们的目的不是论证或反对AZM对ENSO的影响，而是表明Jiang等人的分析不足以解决这个问题。为了更深入地了解大西洋-太平洋的相互作用，还需要更多的分析。

期刊介绍： Geophysical Research Letters (GRL) publishes high-impact, innovative, and timely research on major scientific advances in all the major geoscience disciplines. Papers are communications-length articles and should have broad and immediate implications in their discipline or across the geosciences. GRLmaintains the fastest turn-around of all high-impact publications in the geosciences and works closely with authors to ensure broad visibility of top papers.
