Based on monthly summer precipitation data during 1961-2010 from 73 meteorological stations in Hebei province and its vicinity,as well as the NCEP/NCAR reanalysis data and NOAA sea surface temperature(SST) data over the Pacific Ocean during the same and earlier period,the spatial and temporal variations of summer precipitation anomaly in Hebei province and its possible relationship with the circulation and Sea Surface Temperature over the Pacific Ocean are analyzed by using statistic analysis methods including Singular Value Decomposition(SVD).Results indicate that the uniformly drought/flood is the most common pattern for the spatial distribution of summer rainfall in Hebei,and the second pattern is a seesaw of drought/flood between southwestern and northeastern regions.When the 500 hPa height field in the middle and high latitudes of Eurasian region in summer is distributed as negative,positive,negative and positive teleconnection pattern from west to east,the precipitation of Hebei is above normal with the most sensitive areas in the eastern part of Hebei.The pattern of rainy in northeastern Hebei and drought in other regions(Baoding,Xingtai and Hengshui) has a good coupling relationship with the positive phase of PDO distribution over North Pacific SSTA and the El Niño distribution over the Equatorial Central-eastern Pacific SSTA,which is also revealed by Maximum Covariance Analysis diagnosis.A distinct north/south wind anomaly in the wind field of 850 hPa over eastern area of China is presented in drought/flood summers of Hebei.
