Will Japanese nuclear radiation affect China?

If I solve your problem, you will be satisfied after verification. Thank you! At least at present, it has no effect on the diffusion of pollutants in the atmosphere, which is mainly determined by the environmental wind field and atmospheric state. The atmospheric state determines the height range of pollutant diffusion in the atmosphere. If the atmosphere is stable, pollutants can't break through the stable layer, but can only gather at the bottom and spread by the bottom airflow. If the atmosphere is unstable, pollutants will rise to high altitude and be spread to further places by high-altitude strong winds. In addition, the process of rain and snow will quickly settle pollutants to the ground, and the pollutants in the air will be reduced. Therefore, when meteorological conditions change, especially when the wind field is adjusted, the spread of pollutants will also change. Fortunately, the accuracy of numerical weather forecast is obviously improved now, and the period of weather system is about a few days to a week. At least from the rolling broadcast of China Meteorological Bureau, it seems that the pollutants leaked from Japanese nuclear power plants have no impact on China at present. Beijing Regional Environmental Emergency Center constantly updates the nuclear proliferation forecast. If the weather situation changes in the near future, the results of the diffusion model will be adjusted in time. The nearest province in China is at least1000km. Even if the forecast shows that the wind field changes, pollutants may spread to China. Considering the weakening of pollutant diffusion concentration and the settling process, we should have enough time to make emergency response. According to 16, Liu Yun, the forecaster of the National Ocean Forecasting Station, said that according to the forecast at 15 am 10, the current will first move southwest and then east in the next three days. If there is a nuclear leakage pollution source, it will have no impact on China's sea areas. Judging from the influence of ocean currents, Fukushima is located on the east coast of Japan, and the coast is just the intersection of two ocean current systems, namely Kuroshio and Qinchao. These two ocean current systems are the western boundary current in the western Pacific Ocean, with relatively fixed directions and perennial existence. Although two currents, one from south to north and the other from north to south, flow around Fukushima in a complicated way, the general trend is to develop eastward and the current will enter the Pacific Ocean eastward. If there is nuclear leakage pollution in this seawater basin, the impact on China's waters may be relatively small, unless there are special short-term changes, such as strong winds blowing ocean currents to change direction. Generally speaking, it is unlikely that nuclear leakage pollution will affect China through ocean currents, and the public need not panic.
