filled spherical polygon problem

Dear all,

I want to plot many spherical polygons filled with color that cover the whole sphere, but NCL fills some polygons wrongly, that is the entire map has been filled except the polygons. I have asked this question some time ago:

But the problem still exists. The attachment contains the scripts and data. Can anyone solve this problem? Thanks a lot!

Best regards,

Li Dong
