Studies on polar low and water circulation on Norwegian Sea

为了研究北极地区的水循环、天气系统结构、云和降水形成机制，利用遥感仪器在斯堪的纳维亚北极地区和挪威海上空进行了地面观测。1999年1月至4月，在瑞典基律纳安装了一台X波段垂直指向多普勒雷达，收集了4个月的数据。研究发现，斯堪的纳维亚山脉的地形对降水有很大的影响。为了了解这一地区的水循环，有必要了解地形和天气系统之间的相互作用。从1999年10月起，还在挪威海中部的贝尔岛和斯皮茨卑尔根的NY-Alesund进行了气象观测。这些数据集将有助于了解北极地区的天气系统以及水和能量循环。

In order to investigate the water circulation, structures of weather systems, and clouds and precipitation formation mechanism in the Arctic region, ground based observations were carried out using remote sensing instruments in the Scandinavian Arctic region and over the Norwegian Sea.An X-band vertical pointing Doppler radar was installed at Kiruna, Sweden and collected the data for 4 months from January to April in 1999. It was found that precipitation was strongly affected with the topography of the Scandinavian mountains. To understand the water circulation in this area, it is necessary to understand of the interaction between the topography and weather systems. Meteorological observations were also carried out from October 1999 at Bear Island in the central Norwegian Sea and Ny-Alesund, Spitsbergen. These data set would contribute to understand weather systems and water and energy circulation in the Arctic region.
