摘要: 本文通过西昆仑山崇侧冰川区的观测资料。揭示了冰川区和非冰雪区气温的日变化,垂直和水平方向的摘变以及季节变化。结果表明,冰雪区气温的日变化小,而昼夜温差大,全天均为绝热稳定区。非冰雪区白天为绝热不稳定状态,夜晚存在逆温现象。接近冰雪区地带气温递减率较大。水平方向温差主要发生在冰雪区前缘地带。由此,提出了冰川区特有的现象——“冰川锋”,并给出了该地区作为青藏高原最冷区域之一的一些数值。
关键词: 不同下垫面, “冰川锋”, 逆温, 绝热分布, 温度递减率, 冰雪区, 非冰雪区
Abstract: This paper is based on measured data in the Chongce ice cap area of the West Kunlun Mo-untain. The diurnal variation of air temperature in the glacier and nonglacier areas, its variation in horizontal and vertical directions as well as seasonal variation were revealed. The results show that there are small diurnal range of air temperature and large temperature difference be-tween day and night in the glacier area. In general, the atmosphere is in the superadiabatic stable state in the ice/snow region daring the day.
Key words: The glacier front, Inverse temperature, Abiabatic distribution, Lapse rate of temperature, The lce/snow area, The nonglaeier area
