Additionally, Figures 6(e) and 6(f) show that when the IIBT is more intense, the geopotential height in the India-Burma trough region decreases, whereas the air flow in the back of the Arabian Sea trough accumulates, with greater geopotential height values, which is consistent with the analysis of Figures 5, 6(a), and 6(b).
