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.
