Fig. 12From: Model depiction of the atmospheric flows of radioactive cesium emitted from the Fukushima Daiichi Nuclear Power Station accidentMaps of observations (colored circles) and model ensemble means of atmospheric 137Cs concentration in a 3/18/18 h and b 3/19/12 h. Areas identified as plumes with concentration larger than 10 Bq m−3 are encircled and labeled with the name of the plume. JMA-MANAL wind vectors at 1000 hPa are superimposedBack to article page
