GOKURAKU dcpam5-plane

Introduction

This document is tutorial for performing experiments easily with dcpam5-plane.

As an aside, "GOKURAKU" means "easiest".

Building dcpam5

Build dcpam5-plane referring to dcpam5-plane Installation Guide. Work until "Compile source code" in "How to build".

After building, executable files dcpam_main, init_data, sst_data are created under "src/main" directory. Some NAMELIST files (with suffix ".nml") are prepared in in "src/sample_nml" directory.

$ ls src/sample_nml
dcpam_ape_P21Q21L16.nml
dcpam_hz08_P29Q29L24.nml
dcpam_p04_P21Q21L20.nml
dcpam_p04_P42Q42L20.nml

Baroclinic wave experiment by Polvani et al. (2004)

A method to perform a baroclinic wave experiment by Polvani et al. (2004) is described.

Overview

This experiment does not require additional data, such as SST data. Thus, the experiment is performed with the following 3 steps:

Preparation of directory for experiments
Preparation of initial condition
Execution of experiments

Create initial data file

Create initial data file "init_P42Q42L20.nc" using "init_data" and "init_data_p04_P42Q42L20.conf"

$ ./init_data -N=init_data_p04_P42Q42L20.conf
...

Run the experiment

Using an executable files 'dcpam_plane_main' and a NAMELIST file dcpam_p04_P42Q42L20.nml, execute 'dcpam_main' as follows. This program will be finished in few minutes - tens of minutes.

$ ./dcpam_main -N=dcpam_p04_P42Q42L20.nml | tee p04.log
