By using the 44a (1961-2004) monthly precipitation data at 61 meteorological sta tions in Shanxi Province and NCAR/NCEP reanalysis data, the unusual characterist ics of general circulation in drought and flood years of Shanxi are investigated . The results show that in the year of drought (flood), a positive (negative)n egative (positive)positive (negative) distribution of the 500hPa geopotentia l height anomaly is presented in the mid high latitudes over Europe and Asia i n spring and summer. In the area of mid high latitudes, a zonal circulation ( meridional circulation) is displayed primarily, and evidently weaker (stronger) activity of the cold air is also displayed. At the same time a distinctly nor therly (southerly) wind anomaly is presented in the wind field of 850hPa over ea stern area of China.
