Seasonal analysis reveals rainfall patterns in eastern Australia, indicating jet stream connections.
Seasonal mean 200 mb charts were constructed corresponding to widespread rains in two regions of eastern Australia for a period of 10 years, and mean geostrophic vorticity advection fields found from them. These were related to surface weather patterns, the amount and distribution of rain, and comparisons made between seasons and classes of rainfall episodes.
