1. Anticyclones have an important and contrasting influence on UK weather. AQA Geog A Textbook page 60 - 61

4. Winds in an anticyclone circulate in a clockwise direction in the northern hemisphere

6. What do they look like?

9. Exam questions AQA A 2004 Q9 Explain the typical weather associated with an anticyclone (6 marks)

10. Level 1 Basic (1-2 marks) Basic points, may only consider summer or winter and may be a concentration on the weather rather than its explanation . it is hot and dry winds are light little cloud cover frost and fog in winter etc. Level 2 Clear (3-4 marks) Clear statements, may only consider summer or winter e.g. winds are light because isobars are far apart, it is hot as there is no cloud cover, it is dry because no clouds, frost in winter because very cold with clear skies. Level 3 Detailed (5-6 marks) Some reference to both winter and summer and more understanding of atmospheric processes e.g. winds are light because isobars are far apart indicating a low pressure gradient; no cloud cover allows high summer temperatures as there is maximum heating by the sun, in winter the clear skies and long hours of darkness lead to maximum radiation and so temperatures fall below zero making frost likely. Accept explanations of radiation fog, subsiding air. Temperature inversions, blocking anticyclones as appropriate
