| 摘 要： | 2005年7月至8月,中国北极黄河站第二次科学考察期间,科考队员针对黄河站附近首次队踏勘选定的两条典型冰川(AustreLov啨nbreen和Pedersenbreen),开展了以监测冰川物质平衡和冰川运动为主要内容的研究课题。本文分析了利用差分GPS进行北极冰川运动监测的可行性和优越性;初步处理了首期GPS监测的数据,并进行了精度分析,得出了较为满意的结果;针对北极冰川特殊的地理环境,探讨了在北极冰川上进行GPS测量应该注意的问题。 |

| Abstract: | The variations of sea ice are different in different regions in Antarctica, thus have different impacts on local atmospheric circulation and global climatic system. The relationships between the sea ice in Ross Sea and Weddell Sea regions and the synoptic climate in summer of China are investigated in this paper via diagnostic analysis methods by using global sea ice concentration gridded data covering Jan.1968 through Dec.2002 obtained from Hadley Center, combined with Geopotential Height on 500hPa and 100hPa over North Hemisphere and monthly precipitation and air temperatures data covering the corresponding period over 160 meteorological stations in China obtained from CMA (China Meteorological Administration). Results disclose that both these two regions are of indicative meanings to the climate in summer of China. The Ross Sea Region is the key sea ice region to the precipitation in Northeast China in summer. More sea ice in this region in September will result in less precipitation in Northeast China in the following June. Weddell Sea Region is the key sea ice region to the air temperature in Northeast China in summer. More sea ice in this region in September will contribute to lower air temperature in Northeast China in the following June. |
