Sun, Heat, Air and Wind: weather instruments, wind speed and direction

The video tutorial explains how meteorologists use various weather instruments to measure and predict weather conditions. It covers the use of thermometers to measure temperature, wind vanes to determine wind direction, and wind gauges to assess wind speed. The tutorial also discusses the historical use of wind for generating power and performing work, as well as the importance of understanding wind speed to predict storms and ensure safety.

What is the primary purpose of using a thermometer in weather prediction?

• To calculate humidity levels

• To measure wind speed

• To determine the amount of sunlight

• To assess the temperature of the air

How did people historically determine the direction of the wind?

• By feeling the wind on their skin

• By observing the clouds

• By using a wind vane

• By using a thermometer

What is a modern use of wind that was not possible before the discovery of electricity?

• Generating electricity

• Grinding wheat

• Pumping water

• Sailing ships

What does a wind gauge measure?

• The direction of the wind

• The speed of the wind

• The temperature of the air

• The humidity level

What might happen if the wind speed is very high?

• It will be a calm day

• The temperature will rise significantly

• It could blow the hat off your head

• It will rain heavily
