    Hi,

    Is there a way to plot wind flags (conventional wind symbols of u, v components of wind) in cross section at pressure levels?

    Thanks in advance

      Hi Christos,
      would this example help you?
      Cross Section 3D Parallel Wind Component Example

      You can replace the arrows with flags using something like this code:

      wind_flags = mv.mwind(
    legend                  = 'on',
    wind_field_type         = 'flags',
    wind_flag_length        = 0.8,
    wind_thinning_factor    = 10.,
    wind_flag_calm_below    = 15,
    wind_flag_origin_marker = "circle",
    wind_flag_colour        = 'chestnut

      Cheers,
      Milana

        Thank you for the prompt reply Milana. However, i want to plot the horizontal wind speed in flags that includes u and v components of wind and not the vertical wind speed (w).

    Hi,

    In the Cross Section 3D Parallel Wind Component Example you can see the 3D wind components projected onto the cross section plane. Unfortunately, there is no option in Metview's cross section module to render the 2D wind arrows/flags into the plot. However, there might be some non-trivial ways to generate a plot like that. I will try post a solution.

    By the way, the plot  in this example is a Hovmoeller diagram, although it looks similar to a cross section plot it is quite different to it. Do you want to plot the 2D wind into this type of time-heigh section diagram or into a cross section?

    Kind regards,

    Sandor

      Thanks for the detailed information, Sandor.

      In fact, I want to plot the 2D wind into both diagrams!

      Best regards,

      Christos

        Hi Christos,

        I moved this whole discussion to JIRA, please see issue SUP-3440 - Getting issue details... STATUS .

        Kind regards,
