Recap what is happening at the two fronts in cross-section of depression on p.194
Precipitation
1.Fill in blank table on weather through a depression (Make corrections)
2.Draw sketch of depression and fill in details on weather through a depression
3.Describe how the weather changes as a depression passes overhead (Test question)
4.Symbols on a weather map
5.Draw sketch of a depression and put in an appropriate weather station at each stage
of a depression
6.Other features of a depression
 Winds are anti-clockwise
 Winds are “backing” SE > S > SW > W > NW
 Isobars are close together so winds are stronger
 Lowest readings are in the centre of a depression
 Readings go up or down in fours
7.Formation of occluded front
8.Satellite photos of a depression
9.Sample questions/past paper questions on weather maps and depressions
Anticyclones
1.Features – high pressure in centre, isobars far apart, light winds, winds in clockwise
direction (Draw sketch)
2.Summer weather in anticyclone
3.Winter weather in anticyclone (Note similarities (blue), differences(red))
4.Satellite photos
5.Past Paper Questions
Relief Rainfall – it’s influence on the British Isles
Forecasting the weather
1.Collecting data
2.Range of forecast
3.Value of forecasting, groups of people who value it.
Factors which cause variations in the climate of Europe
1.Altitude
2.Latitude
3.Continentality
4.Prevailing winds
5.Summarise climatic differences on a map of Europe
The impact of climate on farming
Global Warming
