[ncl-talk] question for Wheeler-Kiladis plot

[lzl]

Hi , 
I am using "wkSpaceTime" function for looking at the kelvin waves and mix rossby waves. I would like to know, how to decide the suitable numbers of : 
"nDayWin"(Wheeler-Kiladis temporal window length days), and 
"nDaySkip" (days between temporal windows negative means there will be overlapping temporal segments)

Thank you very much for your help

Best,
Leslie
