RE: [ncl-talk] To match overlayed variables

Dear Jin-Young Kim,

First of all you need to declare latitude and longitude as a dimension of u,
v, wind and p

For an example:

u!0 = "lat1d"

u&lat1d=lat1d

u!1 = "lon1d"

u&lon1d=lon1d

Your overlay wind vector occupies smaller area because you plotted the
vector for u(::6,::6),v(::6,::6) whereas you plotted wind and p for whole
domain

Also I have a suggestion: Instead of using

;************************************************

; Draw everything for final image

;************************************************

  map = gsn_csm_contour_map(wks,wind,res)

  vcidt = gsn_csm_vector(wks,u(::6,::6),v(::6,::6),vcres)

  cnid3 = gsn_csm_contour(wks,p,cnres3)

  overlay(map,cnid3)

  overlay(map,vcidt)

You can use one "overlay" like

;************************************************

; Draw everything for final image

;************************************************

  map = gsn_csm_contour_map(wks,p, cnres3)

  vcidt = gsn_csm_vector_scalar_map_ce(wks,u(:,:),v(:,:),wind(:,:), vcres)

  overlay(map,vcidt)

Good luck

Debasish

Subject: To match overlayed variables

Greetings,

I've tried to draw the overlayed variables
http://climate.pknu.ac.kr/~jin/Sfc-wind_d02h_06.ps
But it look does not match exactly..

overlayed wind vector looks smaller area.

How do you think so?
Do you have anybody to know the reason?

Best regards,
Jin-Young Kim
