Figure 6: Rose diagram for the Baton Rouge area for the years 1961-1980. Vectors on a wind rose indicate the frequency of occurrence with wind coming from a given direction. The length of a vector reflects total percentage of hours with winds from a certain direction. Center circle represents the frequency of a "calm" wind. Concentric circles extending outward from center represent a five-percent increase.
