What is the weather

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
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
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
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
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
Wind direction

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


Cloud type
Cloud Type

  • Clouds come in many shapes, sizes and heights.


Cloud cover
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
Visibility

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