| Abstract: | Through the probe into the common features in upper and lower levels during the large scale rainstorm in south China area by way of synthetic analysis and dynamic diagnosis, based on multi time scale NCEP/NCAR reanalysis information and TBB information, conclusion is made in this paper as follows: The south China rainstorm area is located at the right side of 200hPa upper level jet stream inlet, under the central divergence field, and, in the mean time, at the north side of 200hPa South Asia high pressure and in mid latitude front ridge divergence current. As to the lower level, the rainstorm area is located at the left side of 850hPa lower level jet stream axis. |
