Climate Report over Japan
Monthly Highlights
In eastern and western Japan, monthly sunshine durations were significantly below normal because the rain front tended to stay over the regions, which brought cloudy and rainy weather there. Monthly precipitation amounts in the regions were significantly above normal as the humid air often flowed towards the rain front from the enhanced high pressure system to the south of Japan. In addition, two typhoons (JEBI (T1821) and TRAMI (T1824)) also contributed to the above normal precipitation, which made landfall in the country and brought heavy rain, wind storm and storm surge nationwide.
