Maps of the atmospheric ¹³⁷Cs concentration at surface level as simulated by the N- and W-models for the periods of a 3/20/6 h to 3/20/21 h and b 3/21/1 h to 3/21/11 h. The observed concentrations are indicated by colored circles. Precipitation maps are also shown for the JMA analysis and the N-model
