[ncl-talk] anomaly plot

[Mary Haley]

Dear Sajede,

Without being able to see your data or run your script, it's almost
impossible to debug your code.

You have several hard-coded index values which we have no way of knowing if
they are correct.

For example, how were index values 1211, 1559, 1583, and 1643 chosen below?

SST2 = SST(1211:1559:12,:,:)
meanClimatology=dim_avg_n_Wrap(SST2,0) ;mean of DECEMBER in period of
1950_1979

exel=SST(1583,:,:) ;extreme elnino 1981
anomexel=exel - meanClimatology
;........................................................................................
el=SST(1583,:,:) ;elnino1982
anomel=el - meanClimatology
;....................................................................................
exla=SST(1643,:,:)

​Did you debug your code to make sure these values are correct? That is,
did you use print and printVarSummary to examine the variables and make
sure you have the correct time indexes?

It is much cleaner and safer to use functions like "cd_calendar", and "ind"
to calculate and select index values for the desired time range. ​

For some cd_calendar/ind examples, see:

panel_33.ncl:
http://www.ncl.ucar.edu/Applications/panel.shtml#ex33

indices_nino_1.ncl:
http://www.ncl.ucar.edu/Applications/indices.shtml

​If you continue to have problems, it would help if you explain what the
code is doing and what these values represent.​ Also, it helps if you
describe why you think the plot is wrong.

Thanks,

--Mary
