With the advent of a fast internet connection, I migrated from that system and started to use the Digital Atmosphere, software produced by US firm Weathergraphics. In those days, synoptic data sets were updated every three hours nowadays it is every six hours.

During this time, my PC was hooked up to my receiver, with neither available for any other use.

To download a complete synoptic data set (needed to produce accurate charts), took up to three hours. This program could receive and decode RTTY weather data and produce live weather charts of various types. In the 1990вЂ™s, when I was studying night-time MF propagation, I used a software suite called Skyview Synop. These software decoders will receive synoptic weather information and produce a range of weather graphs, including synoptic charts, pressure charts, pressure tendency diagrams and wind and temperature charts. To this end, software tools are available for the use of mariners and hobbyists.

You will have to decode these, in order to understand the actual synoptic report. When you do receive RTTY weather updates, you will notice that the actual weather reports for each station appear in a вЂ synopticвЂ™ format вЂ“ as groups of figures ( Fig. You can also try the Zorns-Lemma software for receiving weather data via RTTY and Radio FAX this will also decode synoptic weather data into charts and automatically pull masses of weather data off the internet from NOAA servers and weather buoys around the world. There are various software solutions for receiving the RTTY transmissions including SeaTTY and JVcomm32, both of which will also receive WEFAX transmissions.ДЄ detailed list of weather reception software is available at this URL: The current DWD WEFAX and RTTY transmission schedules from Offenbach ( DDH) and Pinneberg ( DDK), located about 20 km north-west of Hamburg, are available on the DWD website. Therefore, I decided that it would be a worth my while to check whether these systems were still fully operational, given all the new technological developments in the delivery of weather information. It has been quite a while since I have listened to RTTY and WEFAX transmissions. DRM+ is also an option for the International Association of Marine Aids to Navigation Lighthouse Authorities (IALA) вЂ“ in the context of the developing VHF Data Exchange System (VDES). The data files are processed, encrypted and then transmitted to the user, where they are decrypted by the receiver. Other formats can provide some вЂinfotainmentвЂ™ such as audio broadcasting of live sports and/or вЂhomeland-securityвЂ™ broadcasts, intranet and WiFi. These include the provision of nautical data such as electronic charts, Gridded Binary (GRIB) weather data, Differential GPS information, NAVTEX/ NAVDAT and SAFTEY-Net MSI transmissions. With this technology, a variety of maritime applications can be delivered. The transmission capabilities of this form of digital point-to-multipoint broadcasting can provide data services to single ships as well as to larger naval units worldwide. I recently discussed with our editor, Georg Wiessala, a relatively new source of weather data the Digital Radio Mondiale (DRM) datacasting service provided by the company RFmondial. These are still transmitted via HF radio, along with RTTY weather data reports also transmitted by DWD on HF frequencies (see later in this column). There are many other direct transmissions of weather data such as the Radio Facsimile (Fax, WEFAX) charts produced by Deutscher Wetterdienst (DWD, the German Weather Service). Moreover, seafarers can get MSI data delivered by satellite communications and even download weather information from the internet. The relevant maritime meteorological data are also disseminated by means of Coastguard voice transmissions, in the shape of the Maritime Safety Information (MSI) broadcasts.

Furthermore, there are many NAVTEX and HF Narrow Band Direct Printing (NBDP) transmissions containing weather updates. In the British Isles, this includes, of course, BBC Radio FourвЂ™s Shipping Forecast on long wave ( 198kHz).

According to these rules, weather information is delivered in different formats, including by means of broadcast radio. The Safety of Life at Sea (SOLAS) regulations of the International Maritime Organisation (IMO) entered into force in 1980.

There is one piece of important information all vessels at sea require, be they large cruise ships carrying three thousand or more passengers, a super-tanker, a trawler or even a small day boat вЂ“ all of them need up-to-date and reliable, weather information. Robert Connolly explains DRM weather вЂdatacastingвЂ™ to ships, revisits the RTTY transmission mode and looks at synoptic weather forecasts, before diving into the fascinating history of the Shipping Forecast.
