Wind direction: the direction from which the wind originates; a northerly wind blows from the north to the south; usually reported in cardinal directions or in azimuth degrees; variety of instruments used to measure this: windsock and wind vane; on a surface weather map, it is indicated by lines that parallel the wind and extend outward from the center of the station; wind speed: the rate at which the air is moving past a stationary observer, is indicated by barbs
A 'synchronous chart' from Meteorographica (1863) by Francis Galton, pioneer of the study and mapping of weather. The chart represents weather conditions, barometric pressure, and wind direction at a single moment in time across the geographic space of Europe.
Finely coloured example of this early 16th Century map of the World according to the ancients, surrounded by 12 wind heads representing the various wind directions. The maps were designed by Laurent Fries for his edition of Ptolemy's Geographia, first published in 1522. Lorenz (Laurent) Fries was born in Alsace in about 1490. He studied medicine, apparently spending time at the universities of Pavia, Piacenza, Montpellier and Vienna.
Go outside on a windy day to discover the wind's direction with bubbles, at Howtosmile.org. Blow bubbles and note their direction on a map, taking readings from different points around a building in the Wind Mapping with Bubbles activity from Fort Worth Museum of Science and History.
Nº1 Nord-West 0º-90º. Project 360º by 21bis (Frank Dresmé). Graduation project 360° is all about four psychogeographical maps. These maps are the routes between personal destinations in Amsterdam. Every destination in a different wind direction; north /east /south /west back to the north. More at: http://www.21bis.nl/project/26
