Weather and How We Measure It
≈ 18 minWeather is the state of the air outside at a particular place and time. It describes things like:
- temperature — how hot or cold it is,
- rainfall — how much rain falls,
- wind — how strong it blows and from which direction,
- cloud and sunshine.
Weather can change from day to day, and even from morning to afternoon. Scientists measure it with instruments:
- a thermometer measures temperature in degrees Celsius (°C),
- a rain gauge measures rainfall in millimetres (mm),
- a wind vane shows wind direction, and an anemometer measures wind speed.
The instrument we use to measure how hot or cold the air is (its temperature) is called a ______.
A rain gauge measures rainfall. What units does it use?
A rain gauge collects 12 mm of rain on Monday and 8 mm of rain on Tuesday. What is the total rainfall for the two days, in millimetres?
