At a glance, this statistical plot shows climate wind speed and direction. Using a compass-style plot, wind roses show a breakdown of wind speeds and directions. In the plotted data, wind speeds and directions are plotted over a certain period of time, like a month or a year, at a single point on earth. This data is plotted in polar coordinates. The most frequent wind direction at this site is from the northwest, followed by west-northwest.

Wind roses show the distribution of wind speed and direction over a specific period of time at a particular location. Meteorologists, climatologists, and environmental scientists use them to analyze and interpret wind data. Wind roses are used for Visually presenting wind data that's easy to understand, as well as:
- Analyzing prevailing wind directions and speeds.
- Wind direction and speed over time.
- Assessing the effects of wind on the local environment, like air pollution or wind erosion.
- Providing information about wind patterns and potential risks to help engineers design buildings, structures, and wind energy systems. This is essentially informing the design of buildings, structures, and wind energy systems about wind patterns.

Here's how you make a wind rose:
- Draw a big circle to represent the compass.
- Make eight or sixteen equal parts using lines or concentric circles.
- Label each division with its cardinal or ordinal direction (N, NE, E, SE, S, SW, W, NW or N, NNE, NE, ENE, E, ESE, SE, SSE, S, SSW, SW, WSW, W, WNW, NW, NNW).
- From the center of the circle, draw a line to each division. Each line represents how often the wind blows from that direction.
- You can color code or shade each section of the wind rose according to the wind speed (e.g. 0-5 knots, 5-10 knots, 10-15 knots, etc.).

The result is a radial graph that looks like a flower, hence their name. Take a look at the colors in the top diagram. Notice that in the image on the right, a single color wind rose design has been stylized into a corporate logo. The legend shows the ranges of speeds for each one. Also, note the concentric circles in the background. There's a percentage of time over the data-observation-period when the wind blows from that particular direction, and the percentage increases as you move away from the center.

Air quality meteorologists use this data to get a quick overview of a site's pollution distribution. They're used by professionals to design airports, since planes like to take off and land into the wind.

article is good and informative

From Barry - I tried to offer a more detailed look at how air pollution and wind direction affect air quality. As well as how to interpret wind roses and use this data to better understand air pollution, it gives you some tips.

Download a copy of WRPLOT VIEW for free from Lakes Environmental and experiment with it if you're interested.

to answer your questions: 1) yes, 2) yes. :) We've learned this at school. very interesting.

From Barry - Thanks, I expanded on it a bit below.

A couple of questions
by: Kristy


Thanks for posting this. I had a couple of questions.

1) Is a rose diagram for a particular amount of time (for example does it represent the winds over a 24 hour period)?

2) Does straight up represent north on a compass?


From Barry - Here's a bit more, Kristy.

A rose diagram, also known as a wind rose diagram, shows the distribution of wind speed and direction for a specific location.

- Depending on the data available and the purpose of the analysis, a windrose diagram can be created for different time periods. It doesn't have to be 24-hour winds. Depending on the analysis, the time period can vary. Using a rose diagram, you could show wind patterns for a specific month, season, or year.

- Yes, most rose diagrams have north pointing straight up on the compass. It's common in meteorology and cartography. A circular diagram usually has 360 degrees, with 0 degrees (or 360 degrees) representing north, 90 degrees representing east, 180 degrees representing south, and 270 degrees representing west. This orientation allows a visual representation of the prevailing wind directions and their frequencies based on wind direction data.

That is usually the case, anyway.
