What drives NSW weather?
To understand our state’s weather we must view our climate in conjunction with the factors that govern weather and climate across the whole of Australia. The position and topography of our continent produce a diverse range of climatic conditions, many of which have marked seasonal variations. The driving force is the general circulation of the atmosphere. Although this is a global process, it is possible to describe some dominant hemisphere circulation patterns that will help us to understand the seasonal changes of climate in Australia.
