Weather Instruments: Tools for Measuring Our Atmosphere

The video introduces various weather instruments used to measure and predict weather conditions. It covers the anemometer for wind speed, wind vane for wind direction, thermometer for air temperature, barometer for atmospheric pressure, hygrometer for humidity, rain gauge for rainfall, and sling psychrometer for atmospheric humidity. Each instrument's function and operation are explained to help understand their role in weather observation.
