摘要
利用起伏地形下水汽压空间分布式模型,通过插值计算重庆市100m高度和实际地形下月平均和年平均水汽压的空间分布。结果表明:重庆市水汽压的季节变化很明显;而且随着海拔高度的增加,水汽压逐渐减小;各月水汽压的最小值出现在东北山区。
Based on the spatially distribution model of water vapor press under the rugged terrain, the spatial distributions of water vapor press monthly and yearly average at 100 meters and under real terrain in Chongqing were calculated by the interpolation method. The result showed that the seasonal changes of water vapor press in Chongqing were significant. The water vapor press decreased with the increasing of sea level elevation. The lowest water vapor press of each month appeared in the Northeast Mountain Areas.
