Abstract: | The characteristics of circulation corresponding to two kinds of indices of summer monsoon onset over the South China Sea
(SCS) have been discussed using the reanalysis data of the National Centers for Environmental Prediction-National Center for
Atmospheric Research. It is found that there are two patterns of deep convection that occur at different locations and influence
the summer monsoon onset over the SCS. One is over the Asia continent and the western Pacific corresponding to the southwesterly
of summer monsoon prevailing over the northern and central part of the SCS, while the other is near the Philippines that affects
the westerly summer monsoon as prevailing over the central and southern southern part of the SCS. Since these two kinds of
convection affecting the summer monsoon onset do not always occur together, thus the summer monsoon onset time is different
when determined by various indices. |
