Climate Report over Japan
Monthly Highlights
- Monthly mean temperatures were significantly above normal from northern to western Japan because these regions tended to be covered with warm air.
- Monthly precipitation amounts were significantly above normal on the Pacific side of northern Japan and in eastern Japan. Heavy rainfalls were often observed from northern to western Japan due to low pressure systems, typhoons, fronts and moist air. Typhoon HAGIBIS (T1919), which made landfall on 12th October, brought record-breaking heavy precipitation from eastern to northern Japan, and caused floods over a large area.
