What is the function of the anemometer in a RAWS?

The function of the anemometer in a RAWS (Remote Automated Weather Station) is to measure wind speed and direction. This instrument is crucial for understanding atmospheric conditions, particularly in contexts such as wildfire management or aviation where wind patterns can greatly influence safety and operational planning.

An anemometer typically operates by utilizing rotating cups or a digital sensor to capture wind speed, while other mechanisms, such as vanes, are employed to determine wind direction. This data is essential for forecasters and emergency responders, as wind influences fire spread, weather phenomena, and other environmental factors.

The other choices pertain to different types of meteorological instruments. While they are important for weather monitoring, they do not describe the functions of an anemometer specifically. Understanding the distinct roles of these tools can enhance one's knowledge of meteorological systems and their applications in various fields.
