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。

The thickness of the ice cover on the wall surface heat transfer is greater than the thickness of it on the air heat transfer form. The thickness of the ice cover on the wall surface heat transfer along the way changes slowly, but it on the air heat transfer along the way changes significantly. Reducing the entrance velocity, lowering the wall surface or air temperature, the formation of the thickness of the ice cover will increase; in the 3D circumstances, The thickness of the ice cover was relatively uniform in the import of the U-turn model, the ice cover was gradual accumulation in the convex bank when the stream traversed the import of the U-turn model, the thickness of the ice cover in the convex bank was significantly bigger than the thickness in the concave bank. The temperature field under the ice cover tends to be complex because of the existence of the secondary flows. The temperature in the convex bank is greater than it in the concave bank. Compared with the data from experiments, the laws in the numerical simulation are similar with them in the experiments
模拟结果显示:二维情况下,运用壁面传热形成的冰盖厚度大于运用空气传热形成的冰盖厚度,壁面传热形成的冰盖厚度沿程变化缓慢,而空气传热形成的冰盖厚度沿程变化明显,减小入口流速,降低壁面或空气温度等,形成冰盖的厚度都会增大;三维情况下,弯道入口处凸、凹岸形成的冰盖厚度基本相同,进入弯道后,凸岸形成的冰盖厚度逐渐增大,而凹岸的冰盖厚度逐渐减小,受横向环流的影响,冰盖下水流的温度场趋向复杂,并且凸岸的温度小于凹岸的温度;与实验室实验所得数据相比较,数值模拟研究得到的规律基本符合实验规律。
