Fig. 2From: Coherent amplification of the Okhotsk high, Korean trough, and northwestern Pacific subtropical high during heavy rainfall over Japan in August 2021Anomalous atmospheric fields during the heavy rainfall period in August 2021. a Anomalies of SLP (shading; unit: hPa) and geopotential height at 500 hPa (contours; unit: m). b Moisture flux anomaly (vectors; unit: kg kg−1 m s−1) at 925 hPa and its divergence (shading; unit: s−1). SLP anomaly (unit: hPa) is superimposed by thin contours. c Geopotential height anomaly at 200 hPa (shading; unit: m) and wave-activity flux (vectors; unit: m2 s−2). Green contours indicate 20 and 30 m s−1 isolines of the climatological-mean zonal winds at 200 hPaBack to article page
