wind rose [′win ‚drōz]
(meteorology) A diagram in which statistical information concerning direction and speed of the wind at a location may be summarized; a line segment is drawn in each of perhaps eight compass directions from a common origin; the length of a particular segment is proportional to the frequency with which winds blow from that direction; thicknesses of a segment indicate frequencies of occurrence of various classes of wind speed. Wind Rose a graph representing wind conditions at a given location; usually constructed for a month, season, or year, using data gathered over many years. The values of the recurrence of directions (as a percentage of the total number of observations) or of the average and maximum wind speeds corresponding to each rhumb are plotted to scale along eight or 16 rhumbs in the form of vectors. The ends of the vectors are joined by a line. Want to thank TFD for its existence?
