The WRF/Chem tracer model is employed to simulate the dispersal of radiation plumes from Japan following the 12 March 2011 Fukushima Daiichi Nuclear Power Plant accident. From a direct comparison between the model simulation and the time-series of Fukushima-derived fission nuclides monitored around southeast Asia, we can distinguish between global transport by the Westerlies in the free troposphere and regional transport by the northeast monsoon in the planetary boundary layer. In general, regional (mainly meridional) transport carried more weight than global (mainly zonal) transport in contributing Fukushima-derived radioactivity to the area covered in this review, particularly at the ground-level sites.
