Weather Instruments

What is the purpose of an anemometer?

• To track the movement of clouds.

• To measure the speed and direction of the wind.

• To calculate the humidity in the atmosphere.

• To measure the temperature of the air.

How does a barometer measure air pressure?

• By counting the number of clouds in the sky

• By using a column of mercury or aneroid capsule to detect changes in atmospheric pressure.

• By measuring the temperature of the air

• By detecting the amount of oxygen in the atmosphere

What does a hygrometer measure?

• pressure of the air

• temperature of the air

• humidity or moisture content in the air

• amount of sunlight in the air

What unit is used to measure temperature with a thermometer?

• Liters

• Inches

• Degrees

• Miles

What is the function of a rain gauge?

• To measure the amount of precipitation

• To determine the humidity level

• To predict the weather for the next day

• To measure the wind speed

How does a wind vane determine wind direction?

• By using a built-in GPS system

• By measuring the speed of the wind

• By detecting changes in air pressure

• The wind vane determines wind direction by using a freely rotating arrow or pointer that aligns itself with the direction of the wind.

What are the different types of anemometers?

• wind anemometers

• cup anemometers, vane anemometers, hot-wire anemometers, and sonic anemometers

• cooling anemometers

• blade anemometers

Explain how a barometer can be used to predict the weather.

• A barometer can be used to predict the weather by monitoring changes in air pressure. A falling barometer reading usually indicates approaching wet and stormy weather, while a rising barometer reading indicates approaching fair weather.

• A barometer can be used to predict the weather by analyzing the color of the sunset

• A barometer can be used to predict the weather by counting the number of clouds in the sky

• A barometer can be used to predict the weather by measuring the temperature of the air

What are the different types of hygrometers?

• Thermohygrometers and Dew Point Meters

• Barometers and Anemometers

• Psychrometers and Electrical hygrometers

• Thermometers and Rain Gauges

What are the different types of thermometers?

• Wireless thermometers

• Glass thermometers

• Acoustic thermometers

• Digital thermometers, infrared thermometers, mercury thermometers, and thermocouple thermometers.
