 Hurray🥳 In 5 seconds we just simulated 10 days of the Earth's atmosphere at a speed of 440 years per day.
-This simulation used a T31 spectral resolution on an [octahedral Gaussian grid](https://speedyweather.github.io/SpeedyWeather.jl/dev/grids/#Implemented-grids) (~400km resolution) solving
-the dry primitive equations. The [UnicodePlot](https://github.com/JuliaPlots/UnicodePlots.jl) will give
