Wind Rose

Wind rose

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, found on nautical charts, as there was no differentiation between a cardinal direction and the wind which blew from such a direction. Using a polar coordinate system of gridding, the frequency of winds over a time period is plotted by wind direction, with colour bands showing wind speed ranges. The direction of the longest spoke shows the wind direction with the greatest frequency, the prevailing wind.

Wind Rose (band)

Wind Rose is an Italian power metal band founded in 2009 in Pisa, Tuscany, by singer Francesco Cavalieri, guitarist Claudio Falconcini and keyboardist Federico Meranda. They have released six studio albums, most recently Trollslayer in October 2024.

Wind

Wind is the natural movement of air or other gases relative to a planet's surface. Winds occur on a range of scales, from thunderstorm flows lasting tens of minutes, to local breezes generated by heating of land surfaces and lasting a few hours, to global winds resulting from the difference in absorption of solar energy between the climate zones on Earth. The study of wind is known as anemology.

Rose

A rose is either a woody perennial flowering plant of the genus Rosa, in the family Rosaceae, or the flower it bears. There are over three hundred species and tens of thousands of cultivars. The plants range in size and form, from trailing and erect shrubs to climbers up to 7 metres (23 ft) in height. Sharp prickles appear on the stems of many species. Their flowers vary in size and shape and are usually large and showy, in colours ranging from white through pinks, reds, oranges and yellows.
