Horizontal drifts of Es patches in three cases (Case 1: May 14, 2010, Case 2: May 21, 2010, and Case 3: May 13, 2012) above the Kanto District inferred by comparing the snapshots at the first epoch (a, c, and e) and 15 min later (b, d, and f). At each epoch, we show the map view (left) and the longitude-height profile (right). Black dashed lines indicate the longitudes used for the profiles
