Climate graphs are a way of showing how temperature and precipitation vary throughout the year for a particular place.

How to construct a climate graph…

2. Work out the right scale for each axis (look at your highest temperature and rainfall figures).
1. Draw and label the axes (remember you need two names for the y axis – ‘temperature’ and ‘rainfall’ ).
3. Draw the graph using bars for rainfall and a line for temperature. Remember to plot the temperature points in the middle of the months on the x axis.

Use this data to draw a climate graph for London.
How does it compare to this climate graph of London?
Using data from an atlas draw a climate graph for another place, in the UK or somewhere else in the world.

At first Anna looks at London.However there is quite a lotof rain in London during October.
Next Anna looks at Oslo. However,Oslo has even more rain than London.
Warsaw does not seem to have much rain in October,but the temperature might be too cold for Mr Strattle.
Eventually Anna finds a city that has a warm averagetemperature in October and does not have toomuch rainfall. Did you reach the same answer? Madrid

Water is neither created nor destroyed. It is cycled round over and over again.
This recycling of water is called the water cycle.
Draw a graph to show where the Earth’s water is stored.

There are three main types of rainfall – relief, convectional and frontal.
In all three situations, rainfall occurs because air rises. Air contains water vapour and as the air rises it cools and condensation can occur. This means that the water vapour returns back into minute droplets of water and falls as rain!

Geographers study the weather because it has an impact on people’s daily lives and the activities that they do.Weather is the day to day changes in the atmosphere.Climate is the overall pattern of weather, usually based on an average over 30 years.The British Isles has a temperate climate. This means that it is not too hot, not too cold, not too dry and not too wet!Water is neither created nor destroyed. It is cycled round over and over again. This recycling of water is called the water cycle.Precipitation is water from the atmosphere. It can be in solid or liquid form. There are three main types of rainfall – relief, convectional and frontal. In all three situations, rainfall occurs because air is forced to rise.
