How To: Measure Wind Parameters

Weather Stations

There are tens of thousands of weather stations distributed across the world. Weather stations are responsible for recording a variety of meteorological parameters.

  • ambient air temperature using a thermometers
  • atmospheric pressure using a barometers
  • rainfall using a rain guage;
  • wind velocity using an anemometers
  • wind direction using wind vanes
  • humidity using a hygrometer;
  • cloud height using a ceilometer;
  • visibility using a transmissometer.

Note: The instruments shown in bold are used in wind applications.



Anemometers can be classified according to their sensors – as shown in the below table:

of operation
Pressure applied to stationary sensorspitot tubes and drag spheres
Momentum transfercups, propellers, and pressure plates
Doppler effectsacoustics and laser
Heat transferhot wires and hot films
Special methodsion displacement, vortex shedding ad more
