A wind rose is a diagram used by meteorologists to give a succinct view of how wind speed and direction are typically distributed at a particular location. Historically, wind roses were predecessors of the compass rose (also known as a wind rose), found on nautical charts , as there was no differentiation between a cardinal direction and the ...
A compass rose or compass star, sometimes called a wind rose or rose of the winds, is a polar diagram displaying the orientation of the cardinal directions (north, east, south, and west) and their intermediate points. It is used on compasses (including magnetic ones), maps (such as compass rose networks), or monuments.
To calculate on a portolan chart the course to follow from a point of origin to a point of destination, one should transfer — using a parallel rule — the "line of course" drawn from the point of origin to the point of destination, on top of the windrose line on the compass rose closest to the ship's position, obtaining on it the theoretical course to be followed when sailing towards the ...
Replica of an ornate compass rose, with letters of traditional winds, a cross pattée (referring to Jerusalem) for east, and a compass needle as north mark, from a nautical chart by Jorge de Aguiar (1492)
From these eight principal winds, 16-wind roses could be constructed with half-winds (NNE, ENE, etc.) which merely combined the names of the principal winds (e.g. NNE would be Greco-Tramontana, ENE Greco-Levante, and so on). 32-wind roses, which were already present in the early 1300s charts, relied on placing quarter-winds in between (the ...

English: Alternative depiction of the wind rose of Aristotle, on the basis of his his Meteorologica.This depiction assumes that eight winds are principal winds (45-degrees) and four are half-winds (22.5-degrees) on a compass rose, and thus their correspondence with modern compass directions (N, NNE, NE, etc.)
