szélmér
Szélmér, or szélmérő, is a device used to measure wind speed and, in many configurations, wind direction. In meteorology and related fields, it is typically referred to as a szélmérő in Hungarian, with szélmér as a shortened form. The instrument is essential in weather stations, ships, aviation, and wind-energy assessments.
Historically, the most common forms are cup anemometers and wind vanes. A cup anemometer uses rotating cups
Electronic and non-moving-part variants include sonic (ultrasonic) anemometers, which measure wind speed by the travel time
Measurement and standards: wind speed is typically reported in meters per second (m/s) or kilometers per hour
Applications: szélmérők are used in weather forecasting, climate research, aviation planning, marine navigation, and wind-energy resource
