8. Pressure and Wind


Weather and Climate: a Teachers’ Guide

Pathway: Basic weather 

Atmospheric and Oceanic Circulation – Climate ZonesAir Masses Pressure and Wind

Lesson overview: In this lesson we introduce air pressure, how differences in pressure can lead to air motion (wind) and how rising and sinking air can lead to low and high pressure respectively. We also introduce the Coriolis Effect and demonstrate how it can lead to rotating weather systems.

The action of the global atmospheric circulation cells, incoming and outgoing heat energy and the influence of upper-atmosphere winds creates areas of ‘high’ and ‘low’ pressure across the world – places where there is more or less atmosphere above the surface of the Earth.  Air is constantly pulled from areas of high pressure towards areas of low pressure, being deflected by the Coriolis effect as it does so, to create winds that circle around High/ Low pressure systems.  Pressure is shown on synoptic weather maps using isobars – lines of equal pressure – and winds blow approximately along these lines. 

Learning objectives:

  • To understand that air has a mass and exerts a pressure.

  • To contrast high and low pressure.

  • To be able to explain why winds are created and the factors that affect the wind.

  • To be able to interpret weather charts
