【摘要】 利用NCAR/NCEP在分析资料,分析2013年2月12日朝鲜核试验3 d内,500 hPa气压场、850 hPa气压场、地面风场。分析朝鲜核试验对中国境内造成影响的气象条件,并对核试验后污染物的扩散范围进行了数值模拟。结果表明,核试验地区的地形不利于污染物向中国传播;核试验区和中国东北南部地区之间,高空受低槽影响,低空受辐合气流影响;12日和14日地面风场吹向中国。模拟结果显示,朝鲜核试验污染影响吉林东南部和黑龙江东南部。更多还原

【Abstract】 Using NCAR/NCEP reanalysis data, analyze the meteorological conditions of 500 hPa atmospheric pressure field,850 hPa atmospheric pressure field and surface wind, within 3 days of North Korea’s nuclear test on 12 February 2013. Analysis on the Meteorological conditions of the impact of Korean Nuclear Test on China. The diffusion range of pollutants after nuclear test was simulated numerically. Results showed that the topography of the nuclear test area is not conducive to the spread of pollutants to China. Between the North Korean nuclear test area and the South of Northeast China, high altitude affected by low trough, low altitude affected by convergent airflow. Ground wind blows to our country on 12 and 14 days. The simulation results show that, North Korea’s nuclear test polluted southeast Jilin and southeastern Heilongjiang.更多还原
