| 摘 要： | 用ＨＥＩＦＥ实验观测资料，给出了临近绿洲的荒漠大气比湿廓线的一些特性。并且用发展的二维中尺度土壤一植被一大气连续体数值模式模拟了绿洲及其临近荒漠大气的湿度廓线结构，再现了荒漠大气的逆湿，得到了荒漠大气比湿廓线几种典型形式及其表现规律，初步解释了荒漠大气逆湿形成的物理过程和机制。

| Abstract: | The characteristics of specific humidity profile of atmosphere over desert near oasis, observed in HEIFE, are given. And the structure of specific humidity profiles of atmosphereover oasis and desert near it is simulated by a developed mesoscale numerical model of edplant-atmosphere continuum. In the simulation, inverse humidity of atmosphere over desertnear oasis is shown numerically, patterns of three kinds of typical specific humidity profileand law of presence of them are obtained, and the mechanism and physical process, formingthe inverse humidity of atmosphere, are explained. |
