There is another big distinction we need to make: some anemometers are part of a larger installation - a weather station for example. Anemometers Integrated into Weather Stations In the early days, people had to count the number of rotations of the anemometer to determine wind speed. This means that the data from the anemometer is displayed on a screen. Most wind meters nowadays are digital wind meters. There are many of different types of anemometers: In this section, we will focus on the more common ones. But due to the rotation of the earth, it actually moves clockwise around high-pressure zones and anti-clockwise around low-pressure zones in the northern hemisphere. Air generally wants to move from a zone of high pressure to a zone of low pressure. It is the result of differences in air pressure around the globe.
