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 plotsand 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 informations from various sources like Meteo-France were used to generate a pollution source wind rose.

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. Let's generate random data for wind speed ws and wind direction wd. Several windroses can be plotted using subplots to provide a plot per year with for example subplots per month.

Probability density functions may be plotted. Fitting Weibull distribution is enabled by Scipy. The Weibull distribution is used in weather forecasting and the wind power industry to describe wind speed distributions, as the natural distribution of wind speeds often matches the Weibull shape.

You must be importing something. I have never used the pywrf module, but as far as I recall isn't the wrfout file 3-dimensional for 10m wind speed? It is the other way around in your code. They will have u,v components with which you can calculate wind direction. NCL has a function for that Active Oldest Votes. Sign up or log in Sign up using Google. Sign up using Facebook.

I am trying to make a wind rose from a series of windspeed and direction values. I have an idea of how to write the raw program for doing this as shown below:. The only issue is is how can I have the program reading my data into the arrays ws windspeed and wd wind direction in the above program.

The data is in an ascii file with two columns separated by a space. The first column is wind speed and the second column is wind direction. With wind speed in the first column and wind direction in the second column.

Do you know how to read this type of wind using python so that column one occupies the ws array and column two occupies the wd array in the script above? Learn more. Asked 4 years ago.

This approach is recommended by US-EPA when no reliable data are available for the location of interest. We provide an online meteorological modeling service to order a set of AERMET input or output files for any location of the world, for one ore more years in the past.

A wind rose is a chart which gives a view of how wind speed and wind direction are distributed at a particular location over a specific period of time. It is a very useful representation because a large quantity of data can be summarised in a single plot.

SFC or path and filename to your file and a PNG file with the windrose shown above will be generated in the same folder storing your input data file. If you need more elaborated wind roses and more complex analysis of your data, you might want to evaluate WindRose PRO.
