Weather report - weather report

Japanese: 気象通報 - きしょうつうほう

Weather reports are a collective term for meteorological information, such as current conditions, general conditions, forecasts, and warnings. There are three types of weather reports: (1) those that are widely disseminated to the general public within Japan, (2) those that are created for specific purposes within Japan, and (3) those that are created for international operations by the Regional Meteorological Center in East Asia. A single weather report may be a combination of (1) and (2), or (2) and (3), for example.

Weather reports are often transmitted by radio telegraph, telephone, or computerized communication, but can also be transmitted by wired telephone or fax, such as when reports are sent to the media for public information.

Weather information, advisories, and warnings regarding typhoons, heavy rain, heavy snow, etc. are also reported in the same way.

Weather Radio Report

There are various types of domestic and international radio reports:

[1] Japan Meteorological Agency Marine Weather Radio Message (call sign JMC): A radio Morse code broadcast of warnings, general reports, observation results, etc. for domestic and foreign ships in East Asia, the western North Pacific, and the surrounding areas.

[2] Japan Meteorological Agency Weather Radio Replica Report (call signs JMH and JMJ). Radio-replica broadcasts of various weather charts and ocean condition charts for East Asia, the western North Pacific, and surrounding areas, targeted at meteorological agencies and ships in Japan and overseas. There are two types of content, JMH and JMJ. JMH is for general use, while JMJ is primarily for aviation weather.

[3] Tokyo Bolmet Radiotelephone Report: Radiotelephone broadcast of observation results for airports in Japan and the surrounding areas, as well as airport forecasts for major international airports, targeted at aircraft flying both domestically and internationally.

[4] Japan Meteorological Agency Weather Satellite Radio Report: Radio reporting of observation results from weather satellites.

All of this is done according to a schedule.

Weather report for ships

In addition to JMH and JMC, NHK Radio broadcasts weather reports for fishing. The Japan Coast Guard also broadcasts marine forecasts and warnings through its communications system. In addition, meteorological offices broadcast weather reports over radio to fishing boats in communication with their nearest coastal fishing stations.

気象に関する情報すなわち実況、概況および予報、警報などを総称して気象通報という。気象通報には、(1)国内的に広く一般に知らせるもの、(2)国内的に目的別に作成するもの、(3)東アジアの地域気象センターとしての国際業務用に作成するものなどがある。一つの気象通報が、たとえば(1)と(2)、(2)と(3)のように複合した性格をもっている場合もある。

　気象通報の伝達手段には、無線の電信・電話もしくは電子計算機による通信によるものが多いが、一般周知のための報道機関への通報の場合などのように有線の電話・ファクシミリなどによるものもある。
