The distribution is the phase reverse between the high-latitude and the low-latitude district, which is the most distinctly structure characteristic of the sea level pressure in the north hemisphere.

The zonal distribution of precipitation is two peak value curve tendency in low latitude region and up tendency in middle latitude region and down-up tendency in high latitude region.

The experimental result show that the scheme which utilized index scheme in moistening coefficient is more suitable for mesoscale numerical simulation of Yunnan low latitude plateau.
