TurbulenceConvection (Single Column Atmospheric Model in Julia) provides a framework for testing parameterizations of clouds and turbulence. It is particularly designed to support eddy-diffusivity mass-flux modeling frameworks.

Information about the EDMF parameterization implemented in TurbulenceConvection can be found in:

User Installation

Installation is easy:

(@v1.6) pkg> add TurbulenceConvection

TurbulenceConvection.jl requires Julia 1.6 or higher. If you plan to develop TurbulenceConvection.jl, you may want to clone it instead:

git clone https://github.com/CliMA/TurbulenceConvection.jl
cd TurbulenceConvection.jl
julia --project=integration_tests
julia> ]
pkg> instantiate

Running

$ cd TurbulenceConvection.jl

TurbulenceConvection.jl can be run in the same way that SCAMPy used to, given one of the following cases:

  • Bomex
  • life_cycle_Tan2018
  • Soares
  • Rico
  • TRMM_LBA
  • ARM_SGP
  • GATE_III
  • DYCOMS_RF01
  • DYCOMS_RF02
  • GABLS

with, for example:

julia --project=integration_tests driver/generate_namelist.jl Soares
julia --project=integration_tests driver/main.jl Soares

or by calling our integraion test driver,

julia --project=integration_tests integration_tests/driver.jl --case Soares

or, interactively, with

julia --project=integration_tests
julia> case_name = "Soares" # default is "Bomex"
julia> include(joinpath("integration_tests", "driver.jl"))

Automated plotting

Upon running a particular experiment (described above), comparison plots (against SCAMPy) are automatically generated in, for example, Output.Bomex.01/stats/comparison/.
