Weather maps use colours, numbers, symbols and lines to show us what the weather is, or is predicted to be, at a certain place.
If we know what the symbols mean we can read the weather map. Some common symbols that we will need to know in order to understand the map are:
- H – when we see the letter H, on the map, it indicates an area of High Pressure.
- L – when we see the letter L, on the map, it indicate an area of Low Pressure.
- Circular lines are isobar lines. They show areas of the same Barometric Pressure.
- If colours are used to indicate rainfall or temperature a KEY will be included on the map.
- Numbers can indicate barometric pressure, temperature and/rainfall.
- Arrows with notches show wind direction, The number of notches show the speed.
- A red line with semicircles indicates a warm front.
- A blue line with triangles indicates a cold front.
- A purple line with semicircles and triangles indicates a ‘occluded’ front. An area of air trapped between a cold and warm front.
- A yellow or blue broken line indicates a trough. A trough is a region of low pressure that often precede a cold front.

It is always a bonus when we can combine subjects in our learning. The Go Facts series, by Blake Education, has a non-fiction writing unit based on Climate. Our family enjoyed using this, it includes a book on Forecasting, which fits in nicely with learning about weather maps. You might like to try this with your middle primary aged children, or the season and habitats sets for your younger children.

The Rainy Day Mum has a great post on Weather Forecasting and Meteorology books for kids. I thought these ones looked great!
