| Abstract: | The analysis of the upper level jet stream occurred in a sporadic intensive precipitation process in winter of 1999 found that divergence occurred at the south side of jet stream inlet and its lower level convergence rose. When the Indo Burma trough is active in low level, convection strengthens and Indo Burma trough develops; convergence occurs at the north side of jet stream inlet and its low level divergence goes down, and southward non geostrophic occurs. |

| Keywords: | jet stream sub circulation Indo Burma trough sub tropical high pressure |
