The system began operating on 1 November 1974, and currently comprises 1,300 stations throughout Japan (of which over 1,100 are unstaffed), with an average separation of 17 km (11 mi). Observations at staffed stations cover weather, wind direction and speed , types and amounts of precipitation , types and base heights of clouds, visibility ...
Weathernews LiVE broadcasts six live programmes of three hours each from 05:00 to 23:00 JST every day; [7] the programmes are routinely divided into 30-minute blocks (around 25 minutes of content and intervals of approximately 5 minutes). The remaining hours are filled with updated weather information graphics and no on-air talent; in case of ...
This included providing cloud images for television from Japan's first meteorological satellite Himawari. [6] In October 1991 it provided the world's first weather forecast using entirely 3D CGI graphics to "News Station" (TV Asahi). In 1993 it produced a program for TV Tokyo, Weather Paradise. [7]
The specific configuration may vary due to the purpose of the system. [1] The system may report in near real time via the Argos System, LoRa and the Global Telecommunications System, [2] or save the data for later recovery. [3] In the past, automatic weather stations were often placed where electricity and
Meteorological organizations in Japan have their origins in the 1870s, when the first weather stations started being established in the country. [1] One of these was the Tokyo Meteorological Observatory (東京気象台, Tōkyō Kishō-dai), which since 1956 has been known as the Japan Meteorological Agency (気象庁, Kishō-chō).
The storm, according to the weather agency, is moving southeast at about 15 kph, with wind speeds going up to 65 kph and gusts reaching up to 90 kph. Mobile networks in several parts of Japan affected
Even with the increasing power of supercomputers, the forecast skill of numerical weather models only extends to about two weeks into the future, since the density and quality of observations—together with the chaotic nature of the partial differential equations used to calculate the forecast—introduce errors which double every five days ...
Weather ship observations proved to be helpful in wind and wave studies, as they did not avoid weather systems like merchant ships tended to and were considered a valuable resource. [5] The last weather ship was MS Polarfront, known as weather station M ("jilindras") at 66°N, 02°E, run by the Norwegian Meteorological Institute.
