Backward trajectories calculated for air parcels placed above station B at 1200 JST 15 March 2011. The trajectories are color-coded (a) to distinguish heights (m) of the parcels at station B and (b) according to their heights at each time step. Small and large dots on the trajectories indicate intervals of every hour and 3 h, respectively, after the calculation start time. c Vertical profile of potential temperature (K) above station B at the trajectory start time
