On the basis of 981 d observations at Hefei Site during 4 a period,various empirical expressions showing the relationship between precipitable water vapor(PWV) and surface vapor pressure(SVP) based on mean daily values are analyzed.The calculating results show that coefficients of determination for natural logarithm regression,linear regression and second-order polynomial regression are all larger than 0.820;and the yearly variations of the empirical coefficients for linear regression are rather smaller than for second-order polynomial regression.Second-order polynomial relation between PWV and SVP accords with the real condition better than other relations in Hefei region.
