厄尔尼诺/南方涛动(ENSO)通过调节区域热量和水分通量影响极端降水的发生频率和强度。加州经历了特别强烈的ENSO影响,模型预测与其极端降水不同。目前尚不清楚未来极端降水的不同预测与这些变化信号的模型间差异有何关系。在这里,我们使用“大集合”模拟与多个气候模式沿着耦合模式相互比较项目第5阶段,以调查降水极端变化的范围在加州和ENSO相关的遥相关的影响。我们发现,降水量的增加在厄尔尼诺期间相对于拉尼娜年要大得多,主要是由不同阶段极端事件频率的差异造成的。对于大多数极端事件,ENSO驱动的影响甚至大于整体气候变化信号,这意味着极端降水变化的ENSO相关SST变率的模型间差异的不确定性。
The El Niño/Southern Oscillation (ENSO) affects the occurrence frequency and intensity of extreme precipitation through modulations of regional heat and moisture fluxes. California experiences particularly strong ENSO influences and models project different to its extreme precipitation. It remains unclear how diverse projections of future precipitation extremes relate to inter‐model differences for those changing signals. Here, we use “large ensemble” simulations with multiple climate models along with the Coupled Model Intercomparison Project Phase 5 to investigate the range of precipitation extreme changes over California and the influences from ENSO‐related teleconnections. We found that precipitation amount increases are much larger during El Niño relative to La Niña years, mainly caused by the differences in frequency of extreme events during different phases. The ENSO‐driven effect is even larger than the overall climate change signal for the most extreme events, implying uncertainties from inter‐model differences in ENSO‐related SST variability for extreme precipitation changes.
