Atmospheric Vapor Content over China and Its Climatological Evaluation Method

  • 摘要: 该文根据中国高空气候标准值 (1971—2000年) 逐月数据集124个探空站资料,计算出各站的整层大气水汽含量,并绘制出年水汽含量分布,除青藏高原地区外,其余地区基本上呈纬向分布。继而配合我国地面气候标准值逐月数据集的水汽压和地面气压数据,在对水汽压进行相应的订正后,将其与整层水汽含量进行相关分析,拟合出全国普遍适用的、统一的或分月的线性经验表达式。拟合结果与实测值之间的均方根误差为0.25 cm。文中还详细讨论了多项式不同次数对拟合结果的影响,结果表明:与数据点走向拟合较好的多项式,次数高其结果并非误差最小。利用经地面气压订正的地面水汽压 (x) 与整层水汽含量 (y) 的拟合公式为y=0.185x+0.093,其最大优点是站点无论高低、不分地域普遍适用。
