Anemometer is a device for measuring wind speed and wind pressure. Anemometer is an important tool for meteorologists who study weather patterns. The most common type of anemometer has three or four cups attached to a horizontal arm attached to a vertical bar.
When the wind blows, the Cup will rotate and make the rod rotate. The stronger the wind blows, the faster the spinning rod eats. According to National Geographic, anemometers are used in almost all weather stations. Wind speed helps indicate changes in weather patterns.
This type of anemometer is used in speed experiments. Typically, laser anemometers are used to calculate wind speeds around cars, airplanes, and spacecraft, for example. The process of wind is reported from the learning resources of the Ministry of Education and culture (Kemdikbud), wind occurs due to differences in air pressure or differences in air temperature in an area.
This condition is related to the amount of solar thermal energy received by the Earth's surface. In a region, areas that receive greater solar thermal energy have hotter air temperatures with lower air pressures. Therefore, there is a difference in temperature and air pressure between areas that receive greater heat energy with other areas that receive less heat energy so that air flow is formed in the region.
