| 摘 要： | 利用NCAR/NCEP再分析资料,分析2011年3月11日日本地震引起核辐射后48 h内,500 hPa气压场、850 hPa气压场、地面风场,从气象条件分析日本核辐射对我国地区的影响可能。分析表明,核泄漏扩散地区的地形不利于核辐射向我国地区传播。我国东部至日本福岛之间的地区高空受暖脊的影响,地面至低空受辐散下沉气流的影响,核电站泄漏后18 h,辐散气流吹向我国东部沿海和东北地区。

| Abstract: | Using NCAR/NCEP reanalysis data,radiation of March 11,2011 earthquake in Japan within 48 h was studied to analyze the potential impact of nuclear radiation on areas of China at meteorological conditions of 500 hPa atmospheric pressure field,850 hPa atmospheric pressure field and surface wind.Results showed that the topography of the area of nuclear proliferation leakage is not conducive to the spread of nuclear radiation.Due to warm ridge of high altitude in the area from China east coast to Fukushima,as well as downdraft of divergence from low to the ground,after 18h nuclear power plant leakage,the divergent flow would blow to the east coast and northeast China. |
