近年来的研究表明,冬末春初Hadley环流变率的非对称分量(AC)可以用背景海表温度(SST)和与厄尔尼诺-南方涛动(ENSO)相关的SST异常的共同作用来解释。但AC-ENSO关系对背景SST和ENSO特征的敏感性尚不清楚。使用耦合模式相互比较项目第5阶段的17个气候模式,我们研究了AC-ENSO关系对背景SST和三个ENSO特性的敏感性。大多数耦合模式相互比较项目第5阶段的模式捕捉到了AC的空间结构,并再现了AC-ENSO关系,但AC-ENSO关系具有很大的模式间传播。AC-ENSO关系对ENSO纬向范围最为敏感。ENSO振幅也可以通过影响纬向范围来影响AC-ENSO关系。然而,ENSO纬向范围和背景SST-在一定的阈值以上-对AC-ENSO关系的影响很小。
Recent study shows that the asymmetric component (AC) of Hadley circulation variability during late winter and early spring can be explained by the combined effect between background sea surface temperature (SST) and the SST anomalies associated with El Niño–Southern Oscillation (ENSO). But the sensitivity of AC‐ENSO relationship to background SST and ENSO properties is still unknown. Using 17 climate models from the Coupled Model Intercomparison Project phase 5, we investigated the sensitivity of the AC‐ENSO relationship to the background SST and three ENSO properties. Most of the Coupled Model Intercomparison Project phase 5 models capture the spatial structure of the AC and reproduce the AC‐ENSO relationship, but the AC‐ENSO relationship has large intermodel spread. The AC‐ENSO relationship is mostly sensitive to ENSO zonal extent. ENSO amplitude can also influence the AC‐ENSO relationship by affecting the zonal extent. However, ENSO meridional extent and background SST—above a certain threshold—have little influence on the AC‐ENSO relationship.
