Climate Report over Japan
Monthly Highlights
From the beginning of the month to the first half of the last ten days, cloudy and rainy days were dominant all over Japan, due to the Baiu front and the Okhotsk High. In addition, due to the effects of Tropical Storm DANAS (T1905) and NARI (T1906), monthly precipitation amounts were significantly above normal on the Pacific side of eastern and western Japan. Around the end of the month, sunny and hot days were dominant nationwide since the North Pacific Subtropical High increased its strength and enlarged its area to the main island of Japan .
