[ncl-talk] The result of the conditional expression yields a missing value (mjoclivar_15)

[Dave Allured - NOAA Affiliate]

This error is more subtle.  I took a quick look at the code for
mjoclivar_15.  It looks like it is currently set up for a maximum of 11 or
12 months, but you are trying to plot 24 months.  To begin, try reducing
the time range.

Later you could experiment with increasing certain arrays to accommodate a
longer time range.  However, notice that there will be a trade-off.  The
MJO plot will start to become overcrowded and hard to read.  What do you
think would be better for your project?  A single dense plot, or separate
plots for 12-month periods?
