A wind rose is a graphic tool used by meteorologists to give a succinct view of how wind speed and direction are typically distributed at a particular location. It can also be used to describe air quality pollution sources. The wind rose tool uses Matplotlib as a backend. Data can be passed to the package using Numpy arrays or a Pandas DataFrame.

Windrose is a Python library to manage wind data, draw windroses (also known as polar rose plots), and fit Weibull probability density functions.

The initial use case of this library was for a technical report concerning pollution exposure and wind distributions analyzes. Data from local pollution measures and meteorologic information from various sources like Meteo-France were used to generate a pollution source wind rose.

It is also used by some contributors for teaching purpose.

Some others contributors have used it to make figures for a wind power plant control optimization study.

Some academics use it to track lightning strikes during high intensity storms. They are using it to visualize the motion of storms based on the relative position of the lightning from one strike to the next.

• matplotlib https://matplotlib.org/
• numpy https://www.numpy.org/
• and naturally python https://www.python.org/ :-P

Optional libraries:

• Pandas https://pandas.pydata.org/ (to feed plot functions easily)
• Scipy https://www.scipy.org/ (to fit data with Weibull distribution)
• ffmpeg https://www.ffmpeg.org/ (to output video)
• click https://click.pocoo.org/ (for command line interface tools)
• seaborn https://seaborn.pydata.org/ (for easy subplots)

A package is available and can be downloaded from PyPi and installed using:

$ pip install windrose

$ pip install git+https://github.com/python-windrose/windrose

or

$ git clone https://github.com/python-windrose/windrose
$ python setup.py install
