Climate Report over Japan
<< prev next >>
Monthly Highlights
-Monthly mean temperatures were significantly above normal in western Japan and Okinawa/Amami, and above normal in northern/eastern Japan, because Japan was less affected by cold air.
-Monthly precipitation amounts were significantly above normal on the Sea of Japan side of eastern/western Japan, and above normal on the Pacific side of eastern/western Japan due to the low-pressure systems and fronts. Monthly precipitation amounts were the highest on the Sea of Japan side of western Japan on record for November since 1946. In Okinawa/Amami, monthly precipitation amounts were significantly above normal and monthly sunshine durations were below normal, because the regions were well affected by typhoons and moist air inflow.
-On the other hand, monthly sunshine durations were above normal on the Sea of Japan side of northern/eastern Japan and on the Pacific side of northern Japan, because the regions were well covered by high-pressure systems.
