Measuring and Forecasting the Weather

Measuring and Forecasting the Weather

Review

• The five most important properties of air are temperature, pressure, humidity, wind direction and wind speed and are used for meteorologists to forecast the weather.

• These properties are measured at different altitudes, from the earth's surface to the upper atmosphere with different instruments for each property.

Multiple Choice

Scientists who measure and forecast the weather are called:

• Anatomists of storms

• Forecasters

• Meteorologists

Multiple Select

Instruments that helps us measure the air temperature?

• Liquid thermometers

• Hygrometer

• Maximum-minimum thermometer

Multiple Choice

Falling atmospheric pressure indicates:

• Bad weather

• Good weather

Multiple Choice

• Aneroid barometer

• Barograph

• Mercury barometer

Multiple Select

Instruments to measure relative humidity

• Hygrometer

• Psychrometer

• Aneroidmeter

Wind direction and wind speed

• Wind direction is important because it can signal which way a weather system is rotating; the direction of the winds is so important that they are even named from the direction they come.

• A simple instrument used is a weather vane to indicate the direction of the wind.

Wind speeds

• The instrument that helps us to measure the earth's wind speed is called anerometer
