How To: Measure Wind Parameters
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:
|Pressure applied to stationary sensors||pitot tubes and drag spheres|
|Momentum transfer||cups, propellers, and pressure plates|
|Doppler effects||acoustics and laser|
|Heat transfer||hot wires and hot films|
|Special methods||ion displacement, vortex shedding ad more|
