The Spillane Eddy, Melbourne's own special weather phenomenon
Alex Zadnik, Wednesday June 29, 2011 - 09:08 EST
The fog that drifted back across Melbourne on Tuesday afternoon was a side-effect of
Melbourne's own special weather phenomenon, known as the 'Spillane Eddy'.
The Spillane Eddy occurs under light synoptic wind conditions, often when a large high
pressure system is over Melbourne in winter. On Tuesday morning, light northeast winds
flowing down off the ranges to the north and east of Melbourne carried fog areas down
over Port Phillip Bay. With the sun being on a low angle at this time of year and offering
little in the way of solar heating, the fog lingered through the day. A very weak southerly
sea breeze then carried the fog back across the city during the afternoon.
In some circumstances, this pattern can be repeated day-after-day, resulting in a
recirculation of air pollution from cars and industry. Often the EPA will issue 'smog alerts'
when this occurs. Air quality was only listed as 'fair' across many suburbs on Tuesday.
While fog was still present across Melbourne on Wednesday morning, it should quickly
clear as northerly winds increase ahead of a cold front moving into the Bight. There will be
no return of the fog this afternoon due to the increasing winds.
