procedure gsn_text (
                wks [1] : graphic, ; argument 0
                plot [1] : graphic, ; argument 1
                text : string, ; argument 2
                x : numeric,
                y : numeric,
                res [1] : logical
        )

The argument "text" is argument 2.
It is prototyped as "string".

Your argument 'rcf' is type float.

NCL is creating a temporary string variable
which is passed to the procedure.

If u want to avoid this use something like:

    sprintf("%5.2f", rcf)

    gsn_text(wks,plot,sprintf("%5.2f", rcf),xmax,ymax-50,tres)
    
    or
    
    rstr = sprintf("%5.2f", rcf)
    gsn_text(wks,plot,rstr,xmax,ymax-50,tres)
