Re: panel plot size

[1] You have 60x70 degrees [pretty square :-)]
        res_at_mpMinLonF = 150
        res_at_mpMaxLonF = 220
        res_at_mpMinLatF = 0
        res_at_mpMaxLatF = 60

[2] You are using a cylindrical equidistant projection
        gsn_csm_contour_map_ce
    which will use the ratio [lat]/[lon]

[3] Maybe what you want is

 
      res_at_mpShapeMode = "FreeAspect"
      res_at_vpWidthF = 0.9
      res_at_vpHeightF = 0.3

      see: http://www.ncl.ucar.edu/Applications/tropical.shtml
           Example 4

      Also, see use of vpXf
           res_at_vpXF = 0.1 ; start plot at x ndc coord
