Quiz Module 9 Lesson 3 & 4 -Weather Instruments & Forecasting

Which instrument measures atmospheric pressure?

• Thermometer

• Barometer

• Anemometer

• Hygrometer

What is the primary function of an anemometer?

• Measures wind direction

• Measures relative humidity

• Measures wind speed

• Measures precipitation

A weather vane is used to determine:

• Wind speed

• Rainfall amount

• Wind direction

• Air pressure

Which instrument measures relative humidity in the air?

• Hygrometer

• Rain gauge

• Barometer

• Weather sock

The Automated Surface Observing System (ASOS) provides:

• Only temperature readings

• Manual weather observations

• Historical weather patterns

• Real-time weather data

A radiosonde is typically carried by:

• Weather balloon

• Aircraft

• Satellite

• Ground station

Infrared imagery is most useful for detecting:

• Wind speeds

• Surface temperatures

• Ground moisture

• Air pressure

Water vapor imagery helps meteorologists:

• Track cloud movements

• Measure rainfall

• Monitor ground temperatures

• Detect atmospheric moisture

A station model displays:

• Only temperature data

• Weather patterns for one month

• Multiple weather conditions

• Future weather predictions

Digital forecasts differ from analog forecasts in that they:

• Use computer models

• Rely on past weather patterns

• Use only satellite data

• Require manual calculations
