福岛核泄漏污染物漂移轨迹影响分析

Drift-path Analysis of the Fukushima Nuclear Leakage Pollutant

日本东北部海域地震引发的海啸造成福岛第一核电站核泄漏事故,已经成为全世界关注的环境问题,大量受污染海水排入太平洋。基于北太平洋多年Argos漂流浮标海流资料在去除涡旋运动的基础上进行了分析,分段计算了污染海水前锋到达北太平洋不同区域的路径及时间,并与日本公布的计算结果进行了比较,结果表明二者之间存在较大差异。

The tsunami that was caused by the earthquake in the northeast sea-area of Japan brought on nuclear leakage accident at Fukushima number 1 nuclear power plant. It had been a notorious environment problem. Mass polluted sea water was poured into Pacific Ocean. This paper analyzed the ocean current data and wiped off eddy configuration based on Argos data. Then this paper calculated the path and time that the forward of the polluted sea water flowing into the different area of North Pacific. Compared with Japan＇ s result, the study indicated that there was much difference between the two.
