Zorns Lemma 11.42: New Features 

 

Ulrich Neuber’s Zorns Lemma Wetter Weltweit (World-Wide Weather) weather software (currently in Version ZL11.42) is a comprehensive piece of software and has been a staple for me for years, mostly running autonomously in the background in my shack. Zorns Lemma 11.42 covers transmissions by Fax (F1-C), CW (Morse code), NOAA Satellites, METAR (Meteorological Aerodrome Report), TAF (Terminal Aerodrome Forecast), RTTY (F1-B), NAVTEX, ACARS and SYNOP data (the latter off the internet). As far as I can tell, the addition of (raw) ACARS data is a new one. My main reason for using this software is its ability to download – in a customisable – way, global weather data from a number of specialised servers on the Internet. Zorns Lemma 11.42 accesses, for example, the servers of the US National Oceanic and Atmospheric Administration (NOAA). Downloading these is a one-click operation, which will deliver synoptic weather data to your screen in about five to ten minutes, depending on how many servers you choose to query. These are ‘live’ data, up-to-date in the moment you access them. Wait until you see the synoptic data box appear on the PC screen. By clicking on one of the Continents (not the Country) maps on your screen you can then have Zorns Lemma 11.42 display a wide range of data in a visually attractive manner on a map and show locations of weather stations too. You can customise what you see (isobars, wind arrows, temperatures, and so on). By clicking on what you want, you can populate the map and then save it. Fax images are saved automatically. This is a neat feature for map lovers and weather hobbyists alike. To get WEFAX, Zorns Lemma 11.42 – like other software solutions (for example, SeaTTY, Mscan Meteo and JVComm32)  – copies and decodes, for example, the transmissions of the German Weather Service (Deutscher Wetterdienst, DWD) and of JOMOC at Northwood. The program has a NAVETX option too, of course, and a range of other weather monitoring tools. I love the way in which synoptic data, acquired online and via RTTY, bring up a succession pictures of ships, land stations and weather buys, illustrating where the data actually come from. There is a wealth of detail here that you can explore and visualise, especially in terms of aeronautical and maritime weather. The software currently retails for €22.
