Information on data and analysis for “The Madden-Julian oscillation and the West Pacific warm pool” by D. J. Raymond and Z. Fuchs
Data
- NCEP Final Analysis Data (FNL) can be found at this location. We used 1 degree data for the year 2001. Here, here, and here are the shell scripts used to produce reduced data sets.
- Outgoing Longwave Radiation data were taken from here. Here is the reduced form of the OLR data set.
- Sea Surface Temperature data were obtained from here. Here is the reduced SST data set.
Software
Analysis programs were written in the
Go language with help from our
Candis data analysis package. The characteristics of the free MJO modes were calculated using the
zval program with the help of a
bash shell script which in turn uses the
qplot program in the
Candis package to do plotting. The characteristics of the warm pool circulation were computed using
warmpool2d.
Here are the shell scripts used to produce the figures. The
Candis program
goplot was used to do the plotting.
Modeling
The model results for the homogeneous mode calculation are presented in
here. This is created by running
zval -1 0.35 0 0 -2 1 001.
The output file for
warmpool2d is too big to include here. However, this output, which is needed for figures 8-11, can be recreated by running
warmpool2d < in.001 > out.001. The input file can be found
here. Move the output file to a subdirectory
runs before running the figure shell scripts.
A
Go compiler is needed to compile
zval and
warmpool2d. Also needed is the
Candis Go interface
gocandis. This exists in the Candis package. Either Google's
go or
gccgo will work. The Candis package is readily built on any Linux machine and can also be built on a Mac. With Windows, you are out of luck!
Paper
The latex for the paper resides in the file
paper.tex. All the figures need to be recreated before this is run using
pdflatex.
