Preface

The Climate System Model Development and Application Studies （CSMDA for short） is an International Partnership Program for Creative Research Teams that was started in October 2004 and is supported by the Chinese Academy of Sciences （CAS）. The initial objectives are ＂to develop a sustainable climate system model that can represent the interaction of different spheres in the climate system, to provide a cross-cut research platform for atmospheric sciences, oceanography and other related fields, and to offer theoretical support for developing and improving reasonable short-range climate prediction systems＂.

An analysis of the air parcel trajectories of long- range transport at shanghai

CONCLUSION The analysis of air parcel trajectories affecting Shanghai indicates that the coming-direction of air parcel is different in various months. The transport track of trajectory (backward and forward) is closely related to the synoptic system, and also related to acid rain occurring in Shanghai region. Air pollution and acid rain in Shanghai region have relationship with both the influence of local pollutants and the influence of external pollutants from southwest and northeast.
