Re: Taylor diagram - about "ratio"

Ning

The value of 1.65 is just a plot default, which can be changed by modifying the Taylor diagram script. There is no reason, physical or mathematical, why the ratio should not be higher than 1.65.

Several models/metrics in the CMIP5 ensemble have ratios > 2.5

Subject: [ncl-talk] Taylor diagram - about "ratio"

Hi,

I am doing a Taylor diagram for the first time. My problem is about "ratio".

The definition is:
    ratio: Case_Variance/Reference_Variance

And in "taylor_1.ncl<http://www.ncl.ucar.edu/Applications/Scripts/taylor_1.ncl>: Default Taylor diagram", it tells:
    All ratio values must be between 0 and 1.65
I want to known why it is 1.65? If i calculate ratio bigger than 1.65, is it reasonable?


Thanks
