Shortwave weather broadcasting is a technology that transmits weather information using shortwave radio frequencies. It works by transmitting images encoded with specific codes, including weather maps, forecasts, and marine weather data, allowing receivers to obtain real-time meteorological data. Shortwave weather broadcasting is widely used in fields such as navigation, aviation, military, and scientific research, particularly in areas far from land or where communication networks are unstable.
Receive Japanese JMA weather fax
In the era when internet communication was not well-developed, some long-range ships would be equipped with weather fax receivers (of course, they still exist today) to receive weather fax charts from coastal stations and analyze and predict sea weather conditions. Although information technology is now advanced and it is no longer difficult to obtain marine weather information, shortwave weather faxes can still play a very important role in certain special situations.
Devices: Shortwave radio, receivers, SDR devices that support USB mode...
Software: KG-FAX (computer), JVComm32 (computer), HF Weather FAX (mobile, PC)
If you don't have a device, you can also use an online SDR (which can directly decode).

Here's an example using a Japanese J-MET weather fax:
Japan Meteorological Agency's meteorological radio broadcasting station in Tokyo（JMH）
Primarily serving maritime vessels, it provides real-time analysis data for various meteorological and hydrological conditions on land, in the air, and at sea. It also offers short- to medium-term forecast maps of various atmospheric pressure patterns, weather elements, sea surface conditions, and other physical quantities. Due to the comprehensive range of weather fax information broadcast by the JMH station, it has played a significant role in improving the timeliness and quality of weather forecasts for the North Pacific region.
