Dear Gatoto,

You need to use "data analysis and visualization language" like NCl, GrADS, Python, R .... for extracting WRF output file.

You can find two example of plotting wind map with NCl in following links:

https://www.ncl.ucar.edu/Document/Functions/WRF_arw/wrf_vector.shtml

https://www.ncl.ucar.edu/Applications/wrfgsn.shtml (wrf_gsn_6.ncl)

You can run WRWpost , write in namelist.arwpost only u,v

then by using GRDAS type" open yourfile.ctl" then set time you need and level

set type "set gxout shaded then d mag(u;v)" then "d set gxout vector then d u;v "

'then print jjdf.png'

You can use python or NCL. I will recommend the wrf-python. This module is developed by the NCAR. You can also use pyNGL and pyNIO.

In case you want to use wrf-python, the list of diagnostics is given in the following link:

https://wrf-python.readthedocs.io/en/latest/diagnostics.html and for plotting https://wrf-python.readthedocs.io/en/latest/plot.html.

The few lines code for wind and direction is following:

ncfile = netCDF4.Dataset("wrfout ilef") ws,pd = wrf.getvar(ncfile, "wspd_wdir")[0,:]

For wind vectors use the quiver in the matplotlib of python.

Dear Jaydeep Singh ,

can you give me a python script example to get wind map for example at 60m above ground level?

Gatoto Placide please see the examples on official website of wrf-python. Link is as follows:

https://wrf-python.readthedocs.io/en/latest/user_api/generated/wrf.interplevel.html

You can interpolate the desired 3D field the any pressure or height level.

Dear All,

Thank you for your suggestions. I arrived to get wind map but now I need to limit my plot on a given region/site(For example on the meteorological station site). How to insert that option in my python script.

Dear Jaydeep Singh ,

my question is on how to get a wind map including wind vectors like this one I attached here.
