  • 摘要: 本文分析了El Niño衰减年夏季西太平洋副热带高压(副高)的季节内变化,发现其季节内变化存在两种模态,一种是6~8月的一致偏西,另一种是6~7月偏西,而8月逆转为偏东,其中偏西模态的异常要远大于偏东模态。对偏西模态而言,由于热带北大西洋海温正异常的强迫影响,激发出一个从北大西洋经过欧亚大陆高纬度到东亚的遥相关,抑制了暖池地区的对流,东亚地区位势高度增加,从而导致副高加强西伸。在偏东模态下,热带印度洋海温异常演变与偏西模态类似,但强度偏低,同时热带北大西洋海温正异常在4月达到峰值后衰减,导致两大洋对8月暖池地区对流的抑制作用减弱。此外,由于6~7月暖池海温持续升高,在局地海气相互作用下,8月暖池对流发展,位势高度场降低,从而造成副高减弱东退。因此,副高8月异常主要取决于热带北大西洋海温异常。在预测El Niño 衰减年副高异常变化时,要综合考虑两大洋海温异常的影响。
