New mechanism to explain how El Niño influences East Asian and WN Pacific climate

(Institute of Atmospheric Physics, Chinese Academy of Sciences) Western North Pacific anomalous anticyclone (WNPAC, or referred to as Philippine Sea anomalous anticyclone) is the most important anomalous circulation pattern connecting El Niño and East Asian-western North Pacific monsoon. WNPAC persists from the El Niño mature winter to the following summer and thus is one of the most long-lasting anomalous circulation patterns over the entire tropical climate system. A new mechanism was proposed to explain the maintenance of the WNPAC, which was named as 'anomalous moist enthalpy advection mechanism'.
