Weather and Climate: a Teachers’ Guide
Pathway: Extending Weather
Lesson overview: In this lesson we look at the causes of Low pressure systems and the weather they bring to the UK.
Depressions or low pressure weather systems, bring most of the ‘normal’ and ‘extreme’ weather that we experience in the UK. Driven by rising air, they mix colder and warmer air masses, forming fronts where these meet and bringing a predictable progression of weather as they pass over the UK. Their approach is typically first signalled by high cirrus cloud, which eventually develops into rain-bearing stratus. Once this passes there may be higher temperatures and less precipitation for a while, before towering cumulonimbus clouds arrive bringing heavy rainfall followed by lower temperatures and scattered showers.

To be able to draw and explain weather fronts.
To understand how weather changes in the UK as a depression passes over
