  • Cyclone "ITA" approaching the Northeastern Australia at 19Z on April 9th, 2014

    9th April, 2014

    Japan Meteorological Agency (JMA) announced that beginning of the rainy season ("Bai-u") in Japan in 2014 was May 5 in Okinawa region and May 11 in Amami region. After then, Bai-u began at June 2 in the Kyusyu Island, at June 3 in Shikoku Island, at June 4 in the western part of Honshu Island, and at June 5 in the eastern part of Honshu Island including Tokyo. At June 6, Bai-u finally reached to the northern part of Tohoku eight days earlier than normal year. It seems that Bai-u in June 2014 was slightly different to normal year; record rainfalls were observed in the Kanto area in June; and even in the Hokkaido Island, where does not have rainy season, continuous rainfalls were observed.

  • typhoon No.11 "HALONG" in 2014 captured by the Global Precipitation Measurement (GPM) mission at 10Z on August 9th, 2014

    9th August, 2014

    Global Rainfall Map (GSMaP) product is global rainfall distribution combining data from the GPM Core Observatory and Constellation satellites, which are operated by the international GPM partners, and developed by JAXA. JAXA's Global Change Observation Mission – Water (GCOM-W or "SHIZUKU") satellite, which was launched in May 2012, is also participating to the GPM mission as one of constellation satellites. GSMaP product is 0.1 degree latitude/longitude grid (about 10km grid around the equator) with hourly resolution and provided to users four hour after observation. In addition to satellite only rainfall product, rainfall calibrated by ground-based rain gauge data is also provided to users about three days after observation.

    18th January 2016

    By an extratropical cyclone, widely spread snowfall was observed over the Kanto-Koshinetsu area of the Japan on 17th-18th January 2016. Around the overpass of the GPM Core Observatory (0:30Z 18th Jan.), the snowfall changed to the rainfall. Dual-frequency Precipitation Radar (DPR) onboard the GPM Core Observatory can observe 3-dimentional precipitation with classification of rainfall and snowfall.
