In some cases, the key will give you extra information that you can use. Input a vector to be used as a true North direction for the wind rose or a number between 0 and 360 that represents the degrees off from the y-axis to make North. If a "spoke" is mostly one color, then winds blew mostly at the wind speed denoted by that color. The modern wind rose used by meteorologists gives the percentage of the time the wind blows from each direction during the observation period it sometimes shows the strengths of these winds and the percentage of the time calm air or light winds are observed. KMLDifferent levels of the KML wind rose may have different height above the ground.\u00a9 2021 wikiHow, Inc. The KML wind rose may be completely opaque or have a degree of transparency. KMLThe opacity level of the wind rose can be defined. KMLWind rose plots can be exported as KML files and loaded in Google Earth. The values of the third variables are represented by means of filled circles of different colors. Ternary plotsTernary plots, or polar plots of three variables, can be created when input data are organized in Microsoft Excel files. The values of the third variables are represented by means of filled circles of different size and colors.
The values of the third variables are represented by means of empty circles of different size and colors. Exported data include joint frequency distributions, percentiles, exceeding frequencies, typical day, hourly distribution of directions, hourly distribution of data, and others.Ĭustomizable plotsPlots can be customised selecting colors, titles, number of directions, number of data intervals and many other options.

It is a very useful representation because a large quantity of data can be summarised in a single plot. WindRose PRO3 is a Windows application for analysing and plotting directional variables starting from raw data or from their frequencies.Ī 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.
