Australia's Variable Rainfall 1890–2004

TWELVE MONTH (April-March) AUSTRALIAN RELATIVE RAINFALL POSTER
[A1 size, 594mm wide by 841mm high] ON SALE

Note: This poster replaces a previous version that covered the period 1900 to 1997.

About the poster
Every three to six years, the waters off the Peruvian coast become unusually warm. In South America this leads to heavy rainfall which causes widespread flooding and because this happens around Christmas time, it is known as El Niño, 'the boy child'. In Australia El Niño can mean decreased chances of receiving 'normal' rainfall. This poster shows yearly maps of rainfall relative to historical records from 1890 to 2004. These can be studied in conjunction with the associated graph, which plots the rise and fall of the Southern Oscillation Index (SOI). SOI is based on barometric pressure differences between Darwin and Tahiti, which are a useful indicator of El Niño conditions. This poster is a must for anyone interested in climate and is a powerful educational tool. The poster is printed on 180gsm quality paper finished with a gloss treatment to improve durability.
