If you, like me, are fascinated by what the weather is going to do in a bit finer detail than you’ll ever get from watching the weather on the BBC, then you might be interested in some of the eleven websites that I’ve listed below. They all provide a quick and easy way of looking at NWP forecast data from various models, usually the American GFS, but not always. There have recently been a rash of new websites providing these kind of viewers, and they are increasingly becoming more sophisticated and professional. I’ve tried to put them into some kind of ranking, let me know if you agree, or maybe you know of a website that I’ve missed out completely.
#11 – metvuw.com
A basic GFS viewer from James McGregor in New Zealand, the graphics and maps used are simple and clear once you find them, as are the controls and available map regions, all set in a web page that offers visualisation such as satellite, weather radar and observational data.
#10 – yr.no
The Norwegian Meteorological Institute and the Norwegian Broadcasting Organisation have put this NWP viewer together between them. It’s rather Norwegian centric, rather like the Met Office website is with the UK, and as far as I know it’s their own NWP model that they use. Personally I just like the Meteograms, which in my opinion would be even better if they ran out to T+120 or longer.
#9 – wetterzentrale.de
The Wetterzentrale site has been around for years and was recently was re-sited and the NWP viewer spruced up. I like the basic idea of the graphics that they produce, and the overlay of an MSLP field on top on a colour filled contoured chart of geopotential height seems to be a defacto standard. I also like the ability to access other models from around the world, especially the 20th century reanalysis data that the site provides as well. I think the controls are still a little bit basic and could do with a bit of a makeover.
#8 – ogimet.com
The OGIMET site is an old favourite of mine, and is were I go to download SYNOP data, and even though the guy that runs it has never replied to a single one of my emails over the years, it still displays a comprehensive array of GFS model data for various regions. I like the multi-layered graphics which are clean and simple, the functionality and controls are rather basic though.
The weather outlook viewer controls are just a little bit more sophisticated than those on the wetterzentrale site, but the graphics are very similar. The controls make selection a little quicker, with flyover selection of model time steps by means of the mouse, with a good range of NWP data fields to access and display.
#6 – netweather.tv
The netweather site have a similar approach to that of weather outlook, but if anything the user interface is clearer and more organised. Again the NWP graphics are not that dissimilar to those produced by wetterzentrale and superbly clear.
#5 – tropicaltidbits.com
This site keeps a special eye on tropical cyclones, but that doesn’t stop them enabling their NWP viewer to be pointed at other regions from a variety of NWP models. The graphics offer multiple layers of NWP types which are sharp and clear, and you can view some quite sophisticated overlays on detailed outline maps.
#4 – earth.nullschool.net
The earth viewer from Cameron Beccario has been around for a long while now, but has exquisite animated graphics. The controls are hidden away so as to get the full effect of the viewer when running in full screen mode. What else can you say other than it’s just beautiful.
#3 – windytv.com
The windytv viewer goes a little bit further than the earth viewer, and gives you an always visible interface, that’s not obtrusive and very tastefully designed, I bet behind the facade it probably uses the same vector graphics and mapping though. A really swish NWP viewer which I don’t use often enough.
#2 – ventusky.com
The ventusky viewer is from the same stable as the earth and windytv viewers by the looks of it. I quite like it, even with the slightly gaudy colours that they’ve chosen to use on their wind fields.
#1 – wxcharts.eu
The wxcharts viewer does just about everything that you could want of a NWP viewer in a web browser, and it must be the equal of many desktop weather visualization systems. It’s hard to believe that the developers have packed so much into the display, in which they’ve also managed to include meteograms as well as maps. You can tell that the team that’s put this together are real enthusiasts. The NWP graphics might be static, and not just quite as impressive as the animated maps from ventusky or windytv viewer, but I still think wxcharts as the edge on them in my opinion.
National Met service offerings in comparison
The DWD in Germany just like to keep it simple, why complicated things with those funny isolines and colour filled contours.
Sophisticated stuff from the French, in this screenshot from the Meteo France website. I suppose for the general public this viewer is telling them all that they need to know – generally sunny.
The Met Office are still using the same FAX charts that they’ve been using for the last 50 years or more, they analysis chart still has the same PPVA89 file designator that it’s always had, but at least nowadays it’s in colour. The Met Office have collaborated to produce the Visual Cortex graphics engine which they use on ITV and internally these days. They seem to have placed most of their effort into producing weather forecast videos which they use on their website and social media. It’s a shame that Visual Cortex can’t be used to provide NWP graphical output to a web viewer in a similar way to what ventusky have done, how hard can it be.
At least the Americans are now trying to update their viewers, and have recently started to use GIS web services offered by ESRI I notice.
It’s all very sad when you compare the quality and sophistication in the first eleven NWP viewers with those on offer from some of the worlds National Met Services. The difference is quite stark in most cases, it’s as if these organisations don’t even want to compete, after spending countless millions on the fastest supercomputers, and building the most sophisticated ensemble and deterministic NWP models, they just tire at the last hurdle and leave it to others to provide a web interface for the citizens of their respective countries to use, the question that springs to my mind is, why not?
