Windrose

Windrose- a diagram indicating compass directions on terms of eight principal winds. 



Windrose is the original name of the compass rose, which is used to indicate direction on maps. This windrose shows the directions of the eight major winds- Tramontana, Gregale, Levanter, Sirocco, Ostro, Libeccio, Poniente, and Mistral. Winds were used to determine crop-growing seasons and for navigation of trade ships around the Mediterranean.
