Anemometry is the science of measuring wind speed and direction. It is commonly used in meteorology, aviation, and environmental studies to understand wind patterns and their effects on weather and climate. Various instruments, such as anemometers, are employed to capture this data, providing valuable information for forecasting and research. There are different types of anemometers, including cup anemometers, which use rotating cups to measure wind speed, and hot-wire anemometers, which detect changes in temperature caused by airflow. Accurate wind measurements are essential for applications like aerospace engineering and renewable energy, particularly in the placement of wind turbines.
