The spaghetti plot only shows the perturbed ENS members. Try to add the control forecast (from ENS) and the operational forecast to it as well. You should use different isoline colours for them. Some hints:

• the

  use a thick red contour line. The control forecast is stored in the same file as the perturbed forecast members: spag_ens.grib. Read it in with this code:

  Code Block
  f = read(data: g, type: "cf")

• the

  use thick green contour line. The operational forecast is stored in spag_oper.grib. Read it in with this code:

  Code Block
  f = read("spag_oper.grib")
