Fig. 5From: Coherent amplification of the Okhotsk high, Korean trough, and northwestern Pacific subtropical high during heavy rainfall over Japan in August 2021Spatial distributions of the mean atmospheric fields in August 11–15, 2021. AS+ (shading; unit: m [100 km]−1) and geopotential height (black contours; unit: m) at 200 hPa. Green contours indicate vertical p-velocity at 500 hPa from − 0.5 to − 0.1 Pa s−1 with an interval of 0.1 Pa s−1. The 200-hPa horizontal wind velocity more than 20 m s−1 is superimposed by red contours with an interval of 10 m s−1Back to article page
