11. A brief history of wind direction and wind speed measurement

Following is a chronological list of events related to wind direction and wind speed measurement:

  • The sixth century B.C.: Greece started observing wind directions by using weather cocks.
  • 1797: American meteorologist George E. Curtis developed the two-vane wind-direction indicator that could swing more easily. This was the precursor of the wind vane.
  • 1846: British Robinson created a cup anemometer.
  • 1887: Richard Brothers, Co. of Paris, France, created the anemo-Cinemograph, the precursor of propeller anemometer.
  • 1892: British W.H. Dines developed the Dines anemometer.

The automation of anemometers has benefited substantially from recent development of generator-type anemometers based on the principles of power generation, and frequency anemometers based on the principles of the optical chopper.
