What’s the wind speed right now? How strong is it blowing? If you’re curious about these weather phenomena, you’ll want to learn more about a wind measuring device called the anemometer.
Anemometers are instruments used to measure wind speed, and they come in different makes and sizes. Some are small and portable, while others are huge and mounted on poles. No matter what type of anemometer you have, though, the basic process for measuring wind speed is the same.
How to Measure Wind Speed Using an Anemometer
- The first step is to find a spot where the wind is blowing freely. You don’t want any obstructions in the way, like trees or buildings.
- Once you’ve found a good spot, set up your anemometer and calibrate it according to the manufacturer’s instructions.
- Hold the anemometer so that it’s facing the wind. The cups or blades of the device should be perpendicular to the direction of the wind.
- Gently spin the wheel or crank on the anemometer until all cups are spinning evenly. At this point, look at the scale and take note of the reading.
- Record your readings for later use.
- If needed, repeat these steps at several other locations.
What Factors Can Affect Accuracy?
- Wind direction – If you’re measuring wind in a new area, try to keep your anemometer as perpendicular to the wind as possible. This will help ensure accurate readings. You may also want to take multiple measurements at different angles. That way, you’ll get an average value.
- Distance from the source – The closer your wind direction indicator is to the source of airflow, the more accurate it will be. As with any other type of wind measuring device, make sure nothing is obstructing the airflow by checking around and behind it before taking readings.
- Changes in temperature throughout the day.
Applications of Anemometer
Once you’ve measured the wind speed at different locations, what do you do with the information? There are all sorts of applications for it:
- Meteorologists use anemometers to help them predict weather patterns and provide accurate reports to the public.
- Athletes use anemometers to monitor their performance outdoors.
- Mariners use anemometers to help them avoid dangerous storms at sea.
There are also specific applications that are based on the kind of anemometer you’re using.
