Weather Things: Basic Weather Instruments

The video tutorial explains how meteorologists use various instruments to measure weather elements like temperature, humidity, wind, and air pressure. It covers the use of thermometers, hygrometers, wind vanes, anemometers, barometers, and rain gauges. The tutorial also discusses the evolution of these instruments from traditional to modern automated versions, highlighting their importance in providing accurate weather data.

What is the primary function of a thermometer in meteorology?

• To measure wind speed

• To measure temperature

• To measure humidity

• To measure air pressure

How does a hygrometer measure humidity?

• By using hair that lengthens or shortens

• By using a coil of two different metals

• By using a liquid that expands and contracts

• By using a sealed metal chamber

What does the dew point temperature indicate?

• The temperature at which air pressure is highest

• The temperature at which wind speed is maximum

• The temperature at which dew forms

• The temperature at which humidity is lowest

What instrument is used to determine wind direction?

• Barometer

• Rain gauge

• Wind vane

• Anemometer

How is wind speed typically measured?

• With a barometer

• With a thermometer

• With a hygrometer

• With an anemometer

What does a barometer measure?

• Wind speed

• Air pressure

• Temperature

• Humidity

What is the simplest form of a rain gauge?

• A coil of two different metals

• A tube or container left in the open

• A brightly colored tube of fabric

• A sealed metal chamber
