A study on influences of abnormal moisture transport on Southwest China

The airflow trajectory model based on Lagrange method (HYSPLITv4.9) was applied to diagnose weather and climate. By simulating three dimension trajectory of the target area and using the airflow trajectory pattern based on Lagrange method, time-dependent curve of air mass and height dependent curve of specific humidity of the same air were drawn and the effect of moisture transport on Southwest China was analyzed concretely.
