Weather Instruments and Measurements

This podcast from the Homic Middle School Earth Science Department covers various weather instruments that are frequently mentioned in Regents exams and are essential for meteorologists to make accurate weather forecasts. The instruments discussed include thermometers for measuring temperature, sling psychrometers for humidity and dew point, barometers for atmospheric pressure, anemometers for wind speed and direction, and rain gauges for precipitation. Each instrument's function and the relevant measurement scales are explained, emphasizing the importance of understanding these tools for weather prediction.
