Diurnal cycle of marine atmospheric boundary layer during the 1998 summer monsoon onset over South China Sea

By using the 1950-1999 NCEP daily averaged reanalyzed data and based on the major atmosphere characteristics at 850 hPa during southwest monsoon onset in the South China Sea (SCS), it is suggested an objective atmospheric circulation way to define the onset dates of SCS southwest monsoon.

Based on the NCEP/NCAR reanalysis datasets,the influence of anomalous diabatic heating over the Tibetan Plateau(TP) in spring on the Asian tropical monsoon onset were investigated by performing composite analysis.

Vihma, and the relation between the dynamic and thermodynamic features of upper mixed layer and the summer monsoon onset.

Influences of SSTA over Kuroshio on SCS summer monsoon onset and the western Pacific subtropical high from April to June are investigated.

The characteristics of the surface temperature deviation in East Asia-Tropical Eastern Indian Ocean and its relation to the South China Sea monsoon onset is analyzed by EOF technique.

Multi-year JEDAC data of heat content in upper ocean and NCEP/NCAR reanalysis data were used to analyse the relationship between the heat content anomalies in the warm pool (WP) area of the western Pacific and onset of South China Sea summer monsoon (SCSM).
