Simulation Study of Extratropical Cyclone Activities on the Nuclear Material Dispersion from the Damaged Fukushima Nuclear Power Plant

  • 摘要: 基于拉格朗日粒子扩散模式FLEXPART-WRF,根据Stohl推导的日本福岛第一核电站核事故(下称福岛核事故)发生后40 d内的137Cs排放量数据,对核污染物在中尺度区域的扩散传输进行数值模拟研究,并选取近5年3次典型气旋个例(北方气旋、南方气旋和缓慢移动气旋)进行敏感性试验,以分析不同气旋系统对污染物扩散的影响. 结果表明:福岛核事故发生后,受中纬度西风带影响,核污染物主要向东部太平洋方向扩散;核事故发生后的5 d,受北方气旋和日本南部局地中尺度气旋2次气旋过程的影响,核污染物对日本本土部分地区影响较大,但影响时间不长. 典型气旋个例的敏感性模拟试验结果表明:北方气旋和南方气旋均可使核污染物对日本本土造成一定的影响,但由于气旋移动速度较快,影响日本岛的时间较短,沉降量也较小;当出现缓慢移动气旋影响日本和周边地区时,可致污染物影响日本岛的时间延长,并直接进入东亚大陆.
