The red solid line denotes the PBLH. The white dashed circles highlight SCs, and the green dashed line is the region to the flat area (east of the 47th grid point) and below 2 km altitude in the vertical direction. The three black dots from left to right on the bottom of each figure stand for the positions of BJP, BTP, and TSP, respectively (Supplementary Table 3).
