Lesson details

Key learning points

  1. High pressure systems, when air is sinking, are called anticyclones.
  2. Anticyclones are characterised by dry, stable weather.
  3. Anticyclones have very gentle winds shown by widely spaced isobars on a weather map.
  4. Anticyclones can bring summer heatwaves and very cold conditions in winter.

Keywords

  • Impact - to have an effect on someone or something

  • Pressure - a force pushing or pressing on a given area

  • Heatwave - a prolonged period of abnormally hot weather

Common misconception

The weather associated with an anticyclone stays the same all year around.

Students will analyse images to identify how anticyclones may bring different weather in the summer and winter.

High-pressure systems cause air to move outward and downward in a clockwise direction (in the Northern Hemisphere) or counterclockwise (in the Southern Hemisphere). You could use a spinning top to demonstrate the rotational motion.
