Long term (10 yrs) convective precip average shows numerical artifacts (T127 grid)

Artifacts appear visible. Is there a solver adjustment that can be used, or is this inherent to the numerical scheme? ``` spectral_grid = SpectralGrid(trunc=127, nlayers=8); albedo = AlbedoClimatology(spectral_grid); output = NetCDFOutput(spectral_grid, PrimitiveWetModel, output_dt=Hour(24)); add!(output, SpeedyWeather.LargeScaleRainOutput(),SpeedyWeather.ConvectiveRainOutput(),SpeedyWeather.AlbedoOutput(),SpeedyWeather.SurfaceShortwaveUpOutput(),SpeedyWeather.SurfaceTemperatureOutput()); stochastic_physics = StochasticallyPerturbedParameterizationTendencies(spectral_grid) random_process = SpectralAR1Process(spectral_grid,seed=12345678) model = PrimitiveWetModel(spectral_grid; albedo=albedo, output=output, random_process, stochastic_physics); simulation = initialize!(model, time=DateTime(2000,1,1)); run!(simulation, period=Day(3653), output=true) ``` <img width="3200" height="1600" alt="Image" src="https://github.com/user-attachments/assets/12a0e0db-b127-4a30-a237-d2e2fe41253b" />
