What does a wind rose illustrate?

A wind rose is a graphical representation that indicates the direction and frequency of wind from various points over a specific period. It effectively displays how often the wind blows from particular directions, often alongside information about the wind's speed. Thus, it provides important insights into both the direction of the wind and its varying speeds, allowing for comprehensive assessments of wind behavior over time. This dual capability is valuable in meteorology, environmental studies, and various applications in urban planning, aviation, and renewable energy sectors, such as wind energy development.
