The Arctic is a mysterious far away place. A voyage to Arctic is filled with sweat and tears, sometimes claiming lives, even human lives. In 1995, as expedition leader, Wei Menghua lead China's first scientific investigative expedition to reach the Arctic's North Pole. At 10:55 on May 6, 1995, 3 red signal flares rose high into the sky when China's National Flag appeared for the first time at the North Pole. This was Wei Menghua's achievement.

The Tundra of the Arctic Regions These are the signs of the coming arctic winter:The color of the tundra changes as the water grasses turn brilliant red.The migratory birds gather in flocks along the coast and gradually drift southward.Most of the birds that have spent the brief summer on the tundra now disappear,leaving only the golden eagle,the gyrfalcon,the ptarmigan,and the snowy owl to brave the sunless northern winter.

Over the actic passager on water.mr Haper also said any vessel that plan to enter the north-west water-way must registred at the Canadian costal guard in advance .he said this is a meassure to protect Canadian's intrest in actic area ,:as we all know , sovereignty is by no means a vague concept but the source to spread it's authority and responsibility .and all these meassure will delivery a claer massager to the rest of the world that Canada will hold the responsibility to protect he enviroment and implementation of the actic water areas.
加拿大总理Stephen Harper已经宣布,为了维护加拿大对于北极水路的主权,加拿大将严格管制进入西北航道的船只。Harper先生说所有使用西北航道的船只现在都要向加拿大海岸警卫队登记。他说这是保卫加拿大在北极地区利益的一种方法。"正如你们所知道的,主权不是一个抽象的概念。它传达着一种权威和责任的源泉。这些措施将向世界传达一个清晰的信息:加拿大对其北极水域的环境保护和实施负责。"

According to the energy conservation theory, BOM and CSIM4 were coupled. The BOM has no treatment on transmission solar radiation, which is of great importance when the model is adapted to Arctic Ocean. So the treatment was introduced to BOM. Through numerical test on different lead albedos, it was found that sea ice thickness is not so sensitive to lead albedo, which may be contribute to the lead occupies little ratio within multiyear sea ice pack. The reason of summer over-melt of arctic sea ice is the NCEP reanalysis downward solar radiation being larger than its reality. Then the arctic sea ice climate variability was simulated. Results showed that: simulated ice thickness change is in accord with the submarine investigated mean sea-ice draft changes. Simulated annually maximum ice thickness along the Eurasian continental oceans are closely related to the observed ones. The long-term mean simulated ice motion has the same features of the SSM/I derived ice motion. Sea ice extents in differential sub-regions have same trends comparing to the satellite passive-microwave data derived ones. Simulated ice concentration is closely related to the observed in the Arctic sub-regions. Sea ice flux through the Fram Strait involves ice concentration, motion and thickness. It is a composite criterion for sea ice model evaluation. The simulated ice area and volume export through the strait accord with the satellite derived or statistically reconstructed ones.(5) The simulated ice thickness climate variability and mean sea surface current of the coupled model were analyzed, results showed: the total ice volume in the Arctic Ocean has a significant decreasing trend. The volume variability is of a 10-year timescale oscillation, with two major periods of 12-13a and 18-20a. Mean ice thickness in the arctic sub-seas has different tendencies. It has an increasing trend in the Barents-Kara Sea and Baffin Bay-Labrador Sea, and decreasing in the others. The characteristic time scale of 7-10a wherein the river discharges leads the Fram Strait ice volume export is about the period that river water takes to be conveyed across the Arctic Ocean.(6) Using the simulated ice distribution in the Arctic Ocean and China precipitation, air temperature and SST in tropical key regions, the climate teleconnection were studied. Result showed: When the mean sea ice thickness is large in the central Arctic Ocean and Chukchi-Beaufort Sea , and small in the Barents-Kara Sea and Baffin Bay-Labrador Sea , the precipitation in South China, Tibetan Plateau, and the north part of Northeastern China are always smaller than normal, and v. v. When the mean ice thickness is small in CA, BC, East Siberian Sea and Greenland-Iceland-Norwegian Sea , and large in BL, The air temperature in north-eastern China, the southern of Tibetan Plateau, and Hainan Island, are always lower than normal, and v. v. In addition, when the sea ice is thick in BC and BL, the SST is larger in the middle and eastern Pacific Ocean, and is smaller in the tropical Southeastern Indian Ocean.
由于BOM没有考虑透射太阳辐射的物理过程,研究表明透射太阳辐射对北冰洋的能量收支起到重要作用,因此在BOM模式中引入了对透射太阳辐射的处理;通过对不同水道反照率的数值试验表明海冰厚度对水道反照率的敏感性不强,可能与海冰区水道面积占的比率很小有关;而模式模拟的北极海冰夏季&过度融化&主要源于NCEP再分析资料提供了偏大的太阳短波辐射;对北极海冰的气候变率进行了模拟研究,结果表明:模拟的海冰厚度变化与潜艇探测的海冰吃深度变化具有一致性;模拟和观测的亚欧大陆沿海的年内最大海冰厚度有很好的相关;模拟的海冰移速与长期平均的卫星反演的海冰移速具有相同的速度分布特征;模拟的各个海区海冰面积的变化趋势与卫星反演资料分析的结果基本一致;模拟与观测的主要海洋分区的海冰密集度具有很好的相关:弗瑞姆海峡的海冰体积和面积的输送涉及到海冰密集度、厚度和移动速度,是判断模式模拟能力的一个综合的指标,模式模拟的结果与卫星反演或重建的面积输送、体积输送具有很好的一致性;(5)分析了模拟的北极海冰厚度的气候变率及气候平均表层海流场,结果表明:北极海冰的总体积有显著减少的趋势,北极海冰总体积的变化具有10a际尺度振荡的特点,存在18-20a和12-13a两个主周期;北极海冰的平均厚度在各个海区的变化趋势不同,在巴伦支—喀拉海和巴芬湾—拉布拉多海地区海冰厚度有显著的增加趋势,而其它海区存在减少的趋势;通过对模拟的气候平均表层海流的分析表明,北极河流流量超前弗瑞姆海峡海冰流量7-10年的特征时间尺度与表层海流的气候分布存在着必然联系:(6)利用模拟结果以及中国降水、气温和热带关键区SST资料,讨论了北极各海区海冰平均厚度与中国降水、气温以及热带关键区SST的关系,结果表明:在北极中心海区和楚科奇—波弗特海海冰厚度偏大,在巴伦支—喀拉海以及巴芬湾—拉布拉多海海冰厚度偏小,则中国降水在华南地区、青藏高原和东北北部降水偏少,反之相反;在北极中心海区、东西伯利亚海、楚科奇—波弗特海以及格陵兰海海冰厚度偏小,在巴芬湾—拉布拉多海海冰厚度偏大,则在中国东北地区、高原南部地区和海南岛附近气温偏低,反之相反;另外,北极楚科奇—波弗特海和巴芬湾—拉布拉多海海冰厚度偏大时,在热带中东太平洋海温偏高,而在热带东南印度洋海温偏低。

Based on the data analysis and numerical simulation, the Arctic sea ice climate variability was researched, the result were as following:(1) The analysis on the seasonal cycle of the Arctic Ocean and atmosphere showed that: The seasonal surface wind is somewhat trade wind like in some regions in the Arctic. The surface air temperature is robustly determined from the underlying environments such as sea ice and Greenland glaciers. In the sea ice region the precipitation rate is larger than that of evaporation. Furthermore, the Arctic Ocean hydrology is profoundly influenced by the surrounding rivers discharge. These are the decisive factors on the ocean salinity pattern. Sea ice flux through the Fram Strait is larger in winter than in summer. From the 40s in the 20th century on, the ice volume flux has an increasing trend. The Arctic rivers flood season is about the melt period, the winter rivers discharge has a significant increasing. Correlation analysis shows that 7 to 10 years is a characteristic time scale that rivers discharge leads Fram Strait ice volume export.(2) Considering 9 major arctic rivers, the Arctic Ocean circulation was simulated through BOM. The result shows that: The BOM can reproduce the main Arctic Ocean circulation pattern. The"Islandization"which is commonly used in OGCMs to treat the North Pole, not only influences the ocean current near the pole, but also influences the current in the Northern Atlantic Ocean, thus the bogus island might influence global climate through thermohaline circulation in the Atlantic Ocean.
