项目摘要

For the downsizing, and the upgrade of the specification of the Doppler Sodar, we made a renewal of the ordinal Doppler Sodar. Especially, for the improvement of the efficiency of the observation using the Doppler Sodar, we tried to make a mobile type Doppler Sodar. We tested investigated the specification of the trial production of the Sodar in Ujigawa Hydraulics Laboratory of DPRI, Kyoto University for three months in 2000. After this check period, we used this completed mobile Sodar I n the intensive fog observation in Kushiro in July of 2001. In this observation, we made the integrated observation of the structure of the sea fog in summer time, using the Doppler Sodar, Boundary Layer Radar etc. During the observation, we observed the invading flow of cold air in the lower atmospheric boundary layer.In the middle of August, we joined the intensive observation of the energy exchange between atmosphere and land surface at the eastern coast of Lake Biwa. The development of the mixing layer in the morning of summer time, the local circulation of the land-lake breeze was observed.From December of 2002, this mobile Sodar were installed in the MU radar site of RASC of Kyoto University in Shigaraki and made the long term continuous observation. In this process, we demonstrated the stability of the operation of this mobile Sodar.

由于多普勒雷达的小型化和规格的升级，我们对序数多普勒雷达进行了更新。特别是为了提高多普勒雷达的观测效率，我们尝试制作移动式多普勒雷达。2000年，我们在京都大学Ujigawa水力学实验室对Sodar的试产规格进行了为期3个月的测试研究。在此检查期结束后，我们于2001年7月将完成的移动式Sodar I用于钏路地区的强雾观测。在这次观测中，我们利用多普勒雷达、边界层雷达等对夏季海雾的结构进行了综合观测。在观测过程中，观测到低层大气边界层有冷空气的入侵流。8月中旬，我们参加了琵琶湖东岸大气与地表能量交换的密集观测。夏季时间上午混合层的发展，观测到陆湖风局地环流。自2002年12月起，该移动雷达被安装在京都大学RASC位于新垣的MU雷达站，并进行了长期连续观测。在这个过程中，我们展示了这个移动Sodar运行的稳定性。
