英文摘要: Based on reanalysis data, we investigate the respective roles of the East Asian winter monsoon (EAWM) and El Niño–Southern Oscillation (ENSO) in building an anomalous western North Pacific anticyclone (WNPAC) in winter to the succeeding summer. The isolated ENSO and EAWM parts (termed ENSO res and EAWM res , respectively) are acquired by removing the ENSO–EAWM interdependent part through linear regression. The results suggest that both ENSO res and EAWM res can produce a WNPAC in winter. The ENSO res -related WNPAC dominantly covers the southern part of the western North Pacific, whereas the EAWM res -related WNPAC over the northern part of the western North Pacific. In the subsequent spring and summer, only ENSO res yields a WNPAC, while EAWM res has no effect on the atmospheric circulation over the western North Pacific. Additionally, the Pacific Decadal Oscillation (PDO) can modulate the influence of ENSO res and EAWM res on the WNPAC. There tends to be a much stronger WNPAC associated with ENSO res (EAWM res ) during positive (negative) PDO phases than during negative (positive) ones. © 2019 Royal Meteorological Society Citation statistics:
