2 Learning objectives Why do geographers study the weather?
What is the difference between 'weather' and 'climate‘? European climate – a decision-making exercise Climate graphs What is the water cycle? What is precipitation? Why does it rain? Learning objectives

3 Why do geographers study the weather?
The weather has an impact on many of the things that we do! Can you explain how the weather affects these people? Images represent – doctors, drivers, shopkeepers, builders, tour operators and farmers. There are of course many more groups that could have been included… Opportunity to ask pupils to come up with other reasons as to why the weather is important? The ‘weatherwise’ section of the BBC’s website is a good site for further information

5 What is the difference between weather and climate?
Weather is the day to day changes in the atmosphere. precipitation temperature humidity wind speed This is animated so that the teacher can allow the class the opportunity to brainstorm what the changes in the atmosphere may include! wind direction cloud cover air pressure sunshine

6 What is the difference between weather and climate?
Climate is the overall pattern of weather, usually based on an average over 30 years. Click on the buttons to find out about these types of climate.

7 World climate zones The types of climate can be classified into 6 major zones.

8 World climate zones What climate zone do you live in?
What other climate zones have you visited?

9 World climate zones Imagine that you are a tour operator. Decide which of these pieces of advice you would give to people depending on which climate zone they are planning to visit! If pupils wish to research into the climates of particular places a useful starting point is

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

12 How to construct a climate graph…

13 How to construct a climate graph…
1. Draw and label the axes (remember you need two names for the y axis – ‘temperature’ and ‘rainfall’ ). 2. Work out the right scale for each axis (look at your highest temperature and rainfall figures). 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.

14 Plot your own climate graph

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

17 European climate Climate can make a big difference to people’s holidays.

18 European climate Anna, the travel agent at Travelstar is having to deal with a difficult customer. Mr Strattle is very keen to go away on a city break in Europe. However, Mr Strattle is very fussy about things, especially the weather. He does not want to travel to travel anywhere where it might be cold and he really dislikes rain when he is on holiday.

19 European climate Mr Strattle has decided that:
the holiday must take place in October. he doesn’t want to visit a city where there will be a high risk of rainfall. he wants to visit a city with a reasonable temperature–not too cold. It may be helpful for students to write down the holiday requirements. Mr Strattle has narrowed his choices down to four different cities. Can you help Anna find a suitable destination for him?

20 European climate Students can click on the locations to bring up the climate data. Students could use this data to produce a holiday brochure page for each city. Satellite image of Europe courtesy of NASA.

21 European climate At first Anna looks at London. However there is quite a lot of 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 average temperature in October and does not have too much rainfall. Did you reach the same answer? Madrid

23 The water cycle 70% of the Earth’s surface is covered by water. Store
Oceans and seas 97 Snow and ice (mainly in the Arctic and Antarctic) 2 In the atmosphere or on the land as rivers and lakes 1 Draw a graph to show where the Earth’s water is stored. Water is neither created nor destroyed. It is cycled round over and over again. This recycling of water is called the water cycle.

29 What is precipitation? Precipitation is water from the atmosphere.
It can be in solid or liquid form. Name as many different types of precipitation as you can! An opportunity to make a list of as many types of precipitation as possible: Rain Hail Sleet Snow Fog Dew

31 Why does it rain? 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!

39 Key Ideas 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.
