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

The British Climate
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!

Why is the South of Britain warmer than the North?
Therefore, the sun’s rays are more concentrated in the South rather than the North of Britain.

Why is it warmer in the West in January?
The North Atlantic Drift is a warm ocean current that brings higher temperatures to the west of the UK. The North Atlantic Drift starts its journey in the Gulf of Mexico.

Describe the pattern of rainfall in the UK.Why is there more rainfall in the West of the British Isles?

Why is there more rainfall in the West?
Many of the mountain ranges in the British Isles occur in the West.
The West is therefore more likely to experience relief rainfall.

Why is there more rainfall in the West?
The prevailing wind comes from the SW. This wind blows over the Atlantic, bringing moisture-laden air.
The prevailing wind is the most common direction of wind.

This is a wet day in February. Explain the following…
1) why C is warmer than B. 2) why it is raining at D.3) why A is colder than B.
Can you explain?

What happens to the weather when the air masses meet?
Depressions (low pressure system) form when a cold air mass meets a warm air mass.
The junction between these two different air masses is called a front. A front is associated with a change in the weather.

What happens at fronts?
A cold front means that cold air is coming. At a cold front, cold air pushes under the warm air. This produces strong winds and heavy rain.
A warm front means that warm air is coming. At a warm front, warm air is rising over cold air. This usually produces clouds and rain.

When air sinks and warms this causes a high pressure system. There are clear skies and no rain.
In Summer, clear skies mean that there are no clouds to stop the sun shining through and so days can be warm.
High pressure systems
Cloud free Europe
At night, however, there are no clouds to stop the heat escaping so nights can be cool.

In Winter, high pressure systems give rise to clear, bright days. However, clear skies also mean that there are no clouds to stop the heat escaping and so ice and frost can form.

Synoptic charts
Pressure is shown in millibars.
Isobars are lines joining areas of equal pressure.LOW
Pressure is decreasing towards the middle. This is a low pressure system.
Synoptic charts are charts of surface pressure. They help meteorologists predict the weather.

HIGH
This is a high pressure system. The pressure is increasing towards the centre.
