| 摘 要： | Based on the analysis of NCEP height, wind and OLR data, the influence of spring equatorial
eastern Pacific SSTA on the seasonal change from spring to summer of eastern Asian circulation has been
investigated. Results show that related to the warm (cold) spring SSTA in the equatorial eastern Pacific, the
anomalous anticyclone (cyclone) circulation emerges around the South China Sea and the Philippines, the strong
(weak) west Pacific subtropical high locates to the west (east) of its normal position, which induces to the late
(early) onset of the South China Sea monsoon. The numerical simulations have also shown that the remarkable
influence of spring SSTA in the equatorial eastern Pacific on the spring seasonal change of eastern Asian
circulation will last till summer. |
