Monthly Highlights
- Monthly mean temperatures were significantly above normal in northern/eastern/western Japan because the regions were covered by warm-air and affected by southerly warm air advection. The regional average of monthly mean temperature anomalies was the highest on record for August since 1946 in northern/eastern Japan.
- Monthly precipitation amounts were significantly below normal on the Sea of Japan side of eastern Japan and below normal in northern Japan, and monthly sunshine durations were significantly above normal in northern Japan and on the Sea of Japan side of eastern Japan and above normal on the Pacific side of eastern Japan, because the regions were frequently covered by high-pressure systems.
- Meanwhile, monthly precipitation amounts were significantly above normal in Okinawa/Amami and above normal on the Pacific side of eastern/western Japan, and monthly sunshine durations were below normal on the Pacific side of western Japan and in Okinawa/Amami, because the regions were affected by two Typhoons KHANUN (T2306) and LAN (T2307).
