RainMaker.jl

A repository for the atmospheric general circulation model SpeedyWeather.jl to measure and document precipitation at a given location. In particular, this repository contains functions and a documentation to show off and rank model setups that make it rain as much as possible at a certain location (e.g. UK) within a certain period. New model setups can be submitted and are automatically evaluated and ranked in the documentation to create a leader board for the most successful rainmaker.

Measuring precipitation with RainGauge

RainMaker.jl exports RainGauge which is fully described in the documentation. In short,

using SpeedyWeather, RainMaker

# create a model
spectral_grid = SpectralGrid(trunc=31, nlayers=8)
model = PrimitiveWetModel(;spectral_grid)

# add the rain gauge as callback
rain_gauge = RainGauge(spectral_grid, lond=-1.25, latd=51.75)
add!(model, rain_gauge)

# run the simulation
simulation = initialize!(model)
run!(simulation, period=Day(20))

# visualise 
RainMaker.plot(rain_gauge)

which will produce a Makie.jl plot

Submit to the RainMaker challenge

Create a pull request with a julia script file_name.jl to be placed in the folder /submissions. After executing this script there needs to be in the global scope of that script the following variables defined

• a rain_gauge::RainGauge having measured precipitation of a SpeedyWeather.jl simulation
• an author::String, e.g. author = "Kermit the Frog"
• a description::String describing your model setup in a few words (<6 probably), e.g. description = "3000m mountain in the atlantic" or "300K aquaplanet".

See Submit to the RainMaker challenge and Rules in the documentation for more details.
