Abstract

: Studying the reaction of glaciers to climate warming and the interactions of ice masses with the atmosphere is cognitively highly significant and contributes to understanding the climate change. The results from the modelling of glacier surface ablation by the temperature–index and energy balance models as well as the results of meteorological and glaciological studies on Werenskioldbreen (south Spitsbergen, Svalbard) in 2011 have been analysed to improve the understanding of the glacier system’s functioning in the High Arctic. The energy balance modelling results showed that the radiation balance (58%) and sensible heat (42%) are the main factors influencing surface ablation on the glacier. The energy balance model offers a better fit to the measured ablation than the temperature–index model. These models have to be validated and calibrated with data from automatic weather stations, which provide the relevant gradient and calibration and validation. Presented models are highly suited for calculating ablation in Svalbard and other areas of the Arctic.
斯瓦尔巴群岛Werenskioldbreen的能量质量平衡和温度指数熔体模型
:研究冰川对气候变暖的反应以及冰块与大气的相互作用在认知上意义重大,有助于理解气候变化。通过温度指数和能量平衡模型对冰川表面消融建模的结果,以及2011年对Werenskioldbreen(斯匹次卑尔根南部、斯瓦尔巴群岛)的气象和冰川学研究结果进行了分析,以提高对高北极冰川系统功能的理解。能量平衡模拟结果表明,辐射平衡(58%)和显热(42%)是影响冰川表面消融的主要因素。能量平衡模型比温度指数模型更适合测量的消融。这些模型必须使用自动气象站的数据进行验证和校准,自动气象站提供相关的梯度以及校准和验证。所提出的模型非常适合计算斯瓦尔巴群岛和北极其他地区的消融。
