摘要:
云底二次蒸发导致的同位素动力分馏可显著影响观测的降水同位素组成和大气水线。本文利用海河流域7个监测站点的降水δ2H和δ18O数据,分析了云底二次蒸发对流域降水同位素的影响。结果表明:流域降雨水样的大气水线为δ2H=7.19δ18O-0.74,显著不同于降雪水样的大气水线(δ2H=8.42δ18O+15.88);流域降雨,特别是小降雨(<5 mm)事件,易受到云底二次蒸发的影响,导致其大气水线的斜率和截距均随着降雨量的减小而减小。流域降雨同位素的云底二次蒸发主要受气温和相对湿度控制,随着气温的升高和相对湿度的减小,云底二次蒸发加剧,导致观测的地面降雨富集重的同位素,同时伴随的同位素动力分馏导致流域降水过量氘(d)值以及大气水线的斜率和截距均减小。与平原地区相比较,流域山间盆地地区受“雨影效应”影响,气候相对干燥,其降雨同位素受更强的云底二次蒸发影响。观测期间,流域小的降雨事件占总降水事件的42%,故云底二次蒸发对流域降水同位素具有重要的影响。
