What is the weather?

Weather is the condition of the air around us over a short period of time (from day to day)


The elements of weather

  • Temperature (the amount of heat)

  • Precipitation (water – rain, sleet, hail, snow)

  • Wind speed

  • Wind direction

  • Cloud Type

  • Cloud Cover

  • Visibility (How far can you see?)


Temperature

  • This is a measure of how hot or cold it is. We can tell this by looking at the clothes that people wear. We use a thermometer to measure temperature


Precipitation

  • Water in the air falls to the ground in one of several forms

  • Rain

  • Snow

  • Sleet

  • Hail

  • But also ice and fog

  • We use a rain guage to measure the amount of rain that falls


Wind Speed

  • This tells us how strong the wind is. We can get a good ideas of this by looking at smoke and trees. The Beaufort scale is used to measure wind strength or we can use an instrument called an anemometer


Wind direction

  • This is the direction from which the wind blows – it is measured by a wind vane


Cloud Type

  • Clouds come in many shapes, sizes and heights.


Cloud Cover

  • This is the amount of the sky covered by cloud. It is measured in eighths

    Clear sky

    4/8

    8/8 (Total cover)


Visibility

  • This is the distance that can be seen. It is measured in metres.


What will we use to record the weather?
