%X The Asian summer monsoon trough consists of two major components: the South China Sea(SCS) summer monsoon trough and the Indian summer monsoon trough.Although they both belong to the tropical monsoon systems,and carry the characteristics of the tropical convergence zones,there are significant differences and similarities due to the geographic locations,land/sea,impressed systems,etc.From a climate perspective,this paper focuses on the structural similarities and differences between the South China Sea and Indian monsoon troughs,and also addresses the differences in the evolution of the troughs.First,the similarities and differences of the three dimensional configurations of the two troughs are presented.The results show there are no significant differences between these two troughs.Both carry the characterisics of the tropical convergence zones,that is,convergence in the tough area in the low layers,divergence in the high layers and monsoon vertical circulations.In regard to the thermal feature,it is cold in the trough zones in the low layers and warm in the medium and high layers.The Indian summer monsoon trough is stronger than the SCS one in most factors.Second,the climatological evolution characteristics of both troughs are analyzed.The results show that the occurrence of the summer monsoon trough is in accordance with the monsoon onset.The SCS summer monsoon trough occurs early,retreats late and maintains longer,while the Indian summer monsoon trough occurs late,retreats quickly and maintains shorter.There are also some differences in the temperature and humidity evolution process.
