Decadal fluctuation of aerosol recorded in the ice core and arctic oscilation

极地冰冻圈通过其在地球上的水和能量循环，在全球气候变化中发挥着重要作用。由于纬度热量不平衡，大气环流在赤道上升热空气，并在高空向极地流动。因为空气在运输过程中被冷却并堆积到极地地区。随着空气的循环，各种来源的物质和污染物被输送到极地地区，这些物质被汇编并保存在雪层中。在极地地区发现的冰芯记录了全球气溶胶流动的历史，这是该地区过去气候的有效指标。极地冰冻圈还通过积雪面积的增减决定赤道之间的热平衡。特别是在北极，海冰面积的逐年增加或减少对热平衡有很大的影响，对过去气温和大气气溶胶的波动进行了…估计从北极不同冰川和冰川高原的冰芯记录中获得了更多的氧同位素和化学物质记录。冰芯记录的年代际波动可能反映了气溶胶储存库和大气环流过去的波动。本文讨论了中部地区的Summit和南部地区的Dai3、格陵兰岛的Penny冰帽、Elzimia岛的Agassi冰帽和东北部Svarbal岛的Austfonna获得的冰芯记录。冰芯的测年由年氧同位素比值估算，大气气溶胶的过去波动由冰芯中的化学物质浓度估算。核心数据的时间序列是在北极波动指数下审议的。冰芯氧同位素比值引起的气温年代际波动随地区变化呈现正、负相关关系。进一步的讨论将在全球气候系统下针对北极环境进行。较少

The polar cryosphere plays an important role in global climatic change, through its water and energy cycles in the earth. The atmospheric circulation, as a consequence of the latitudinal heat imbalance, gets to rise hot air at the equator and to flow poleward at high level. As the air was cooled in transit and piled up to polar regions. With the circulation of air, the substances in various origin, as well as the pollutant, were transported to polar regions, which were compiled and reserved in snow layers. The ice core, recovered in polar regions, records the history of global flow of aerosol, which was the effective indicator for the past climate in the area. And also the polar cryosphere decides the heat balance between the equator through the increase and decrease of the area covered by the snow. Especially in the Arctic, the annual increase or decrease of sea ice area get great influence on the heat balance.The past fluctuation of air temperature and atmospheric aerosol were estima … More ted from the ice core record obtained from various glaciers and ice plateau in the Arctic with the oxygen isotopic ratio and chemical substances record in the ice core.The decadal fluctuation recorded in ice core possibly reflects the past fluctuation of activities in the aerosol reservoir and atmospheric circulation.The core records obtained in Summit in the central region and Dai3 in southern region, Greenland, Penny ice cap in Baffin island, Agassi ice cap in Elzimia island, Austfonna in the Svarbal north east island were discussed here. The dating of ice core was estimated annual oxygen isotopic ratio and the past fluctuation of atmospheric aerosol was estimated from the chemical concentrations in ice core. The time series of core data was considered under the Arctic oscilation index. The decadal fluctuation of air temperature induced fromoxygen isotopic ratio in the ice core shows positive and negative relationship depending upon the regions. The further discussion will be available for the Arctic environments under the global climate system. Less
