A Method for Estimating Precipitable Water and Effective Water Vapor Content from Ground Humidity Parameters
用地面湿度参量计算我国整层大气可降水量及有效水汽含量方法的研究

Based on the 1993 ground and radiosonde data of 28 stations in China, some empirical equations about the relation between precipitable water and ground humidity parameters for the 28 sta-tions included in this study are derived; and based on these results and by introducing two parameters, latitude , and height H, to the empirical coefficient parametric equations, an empirical model for esti-mating precipitable water by using ground humidity parameters is developed in this paper. Besides, some empirical equations about the relation between column effective water vapor content and precipitable water for these 28 stations are also derived, and a method for estimating effective water va-por content by using precipitable water obtained from ground humidity parameters is proposed.
