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 :<br>
"nDayWin"(Wheeler-Kiladis temporal window length days), and<br>
"nDaySkip" (days between temporal windows negative means there will be overlapping temporal segments)<br>
<br>
Thank you very much for your help<br>
<br>
Best,<br>
