摘要
利用“中国科学探险协会2002年北极科学探险考察”期间, 在斯瓦尔巴德地区政府所在地朗伊尔宾城架设的两个自动气象站记录的气象资料, 分析了该地区气象要素平均值的日变化, 给出了这一极端环境区夏季近地层气象要素的基本物理图像: 太阳辐射、大气温度、地表温度和大气湿度等气象要素的日变化都呈单峰分布; 地气温差因地而异, 不同下垫面类型大气能量的源汇不同; 局地环流多种多样, 冰川风、海陆风、山谷风相互叠加, 主导风向各地不一。
With the observation data of the surface layer atmosphere by two automatic weather station at Longyearbyen, the capital of Svalbard, which were obtained during the “China Association for Scientific Expedition's Arctic Scientific Expedition 2002”, we studied the diurnal variations of some atmospheric factors in this area. The results show that the variations in summer in such extreme environmental areas are all in unimodal distribution and that the energy source/sink varies with different areas and that there are many kinds of local winds affecting between each other.
