This is a great visualization of free data, although not the first in this style, but it's usefulness in actual forecasting or nowcasting is rather limited. Interpolation between sparse grid points can result in missing fine details, like the subtle boundaries that kick off the most violent storms in the central Plains. Limiting to just GFS and GEM make sense from a proof of concept level, however these are long rang…

Found the storm chaser!

Nice, but the page takes my laptop's CPU from a quiet 2% to a whiny 100%.

I think making sense of the scale of weather would be aided by an accurate world map like the peters projection or something of that nature that doesn't do Eurocentric seafaring things like put Greenland as being the same size as Africa when Africa is like 11 times larger in reality. For example, with a proper map, the fact that much of the northern Atlantic landmass is heated by the sea would make more sense -- it's a much smaller area in reality than is represented.

Great stuff let's not forget https://earth.nullschool.net/#current/wind/surface/level/ort...

It's very interesting being able to drag the different projections around.

Just so you know, wind in Spanish is "viento", and "ventusqui" is an informal way to call the wind. So yep, they've copied both the concept AND the name of windytv.

It seems many people have their locale set to en-us, but don't like seeing °F, inches etc.

Go to Menu > Settings > Language > English [en]

That will give you °C, mm, etc

Everyone misses weatherspark. It's been a year since they went down and there's still no replacement for their historical weather viewer. I know they decided to stop because their flash based API for the radar map was depreciated but even just the historical and predicted line plots of weather data I'd pay money for. Ventusky is no weatherspark replacement and I don't think the models they're drawing their data from…

Do you know if weatherspark used public or private data sources? I've been working on some open source data visualization tools and if the data sets were public perhaps we could build something with weather data sets in mind.

After WeatherSpark shut down I spent a few minutes poking around weather data sources before getting overwhelmed and giving up. It looks like they get all their historical data from Weather.gov. (WeatherSpark lists their data sources here: https://weatherspark.com/about ...and weather.gov appears to have their data available for download from NOAA: https://www.ncdc.noaa.gov/)

While it is undeniably both beautiful and really cool, I've yet to see anything that beats a meteogram[1] when it comes to actually understanding at a glance what the weather is likely to do over the next couple of days. [1] https://en.m.wikipedia.org/wiki/Meteogram

is there an online source for that? (preferabley with coverage of europe for me)

Can you explain the significance of that

ECMWF has been producing the best global forecasts in the world for many years. This will end in few years, but at the moment IFS, the model used at ECMWF, is the best in the world.

why will it end? just curious.

Offshoot topic. How can I find the windiest places in the us? I'm looking to move somewhere warmer and I was thinking a strong consistent wind would mitigate the hot summers.

I live in a windy place, in Europe, and I suggest you to reconsider your decision.

where is Europe? Brussels?
