[ferret_users] how to overlay South Hemisphere latitude on North Hemisphere latitude

[Xiaoyu Bai <xbai1@xxxxxxxx>]

Dear ferreters,

I have zonal averaged variables, say temperature. I want to compare them by latitude, for example, temperature at 30N and 30S. So the figure should be like latitude from 0 to 90 for the x-axis and zonal temperature for the y-axis. What I planned to do was to re-grid the south hemisphere latitude to north hemisphere latitude first then overlay it on top of the north hemisphere zonal averaged temperature. According to my sh grid command, my re-grid process was successful: sh grid south_EB

    GRID SOUTH_EB

 name       axis              # pts   start                end

 XAX       LONGITUDE          257mr   0E                   1.411W(358.59)

 YAX       LATITUDE            65 r   0                    88.928N

 normal    Z

 normal    T

However, when I plot it out, it still "remembers" its original south hemisphere latitude. Is there a way or a better way to compare south hemisphere data to north hemisphere data?

Thank you very much and happy lunar new year!
