In today’s class, we will be talking about weather instruments, symbols and record chart. Enjoy the class!
Weather Instruments, Symbols and Record Chart
Introduction
In the last lesson, we learnt what weather is. We also saw the difference between weather and climate. We looked at various factors that affect weather, weather conditions and how weather determines our actions at times. In this lesson, we will be learning about weather instruments and symbols.
Meaning
Weather instruments are tools required to measure or monitor weather factors or weather conditions.
Weather symbols are used by meteorologists to represent different weather conditions during a weather forecast.
Activity
Stand outside in the cool of the day. Do you feel the wind or air blowing? Can you tell the direction it is coming from or where it is going?
Weather instruments
Below are a few common weather instruments.
Activity
- Draw the diagrams above. 2. What do you think each of the diagrams above is used for.
Some weather Instruments and their function
| Weather Instrument | Function | |
| 1 | Thermometer | Used to measure the temperature of a place or person. |
| 2 | Wind Vane | Used to measure the direction of the wind. |
| 3 | Rain Gauge | Use to measure the quantity or amount of rainfall. |
| 4 | Barometer | Used to measure the pressure of the atmosphere. |
| 5 | Clock | Shows or indicates the time. |
| 6 | Anemometer | Used to measure the speed of the wind. |
| 7 | Hygrometer | Used to measure relative humidity. |
Weather symbols
During weather forecasting, meteorologists make use of different symbols to show or indicate different weather conditions.
Meteorologists use weather symbols to prepare weather charts after predicting the weather. People can then use the charts to make decisions if they would go to a place or not
Activity
Using the above chart as a guide, prepare your own weather chart showing various symbols.
Evaluation
- Mention five weather instruments
- State the function of the instruments mentioned above
- Who is a meteorologist?
- Give five examples of weather conditions
- The speed of the wind is measured with ————
