Wet year for South Australia
Ben Domensino, Thursday September 22, 2016 - 17:02 AEST
We may only be nine months into 2016, however parts of South Australia have already picked an entire year's worth of rain.
The state as a whole recorded its wettest winter in 15 years and wettest autumn in 27 years. Now, just over three weeks into September, spring is already off to a familiarly soggy start for some areas.
The list of places that have already had a year's worth of rain in 2016 includes Adelaide (565mm), Mount Lofty (1090mm), Maitland (545mm), Georgetown (508mm), Cleve (449mm), Elliston (448mm), Streaky Bay (411mm), Snowtown (400mm) and Karoona (309mm). Many of these locations have rainfall data available for more than 100 years and mos are at least 30mm above their annual average already.
Looking at rainfall during the period from January 1st, 2016 up until today, this is also the wettest year-to-date in 70 years for Karoonda, 56 years for Maitland, 48 years for Cleve and 42 years for Whyalla.
The recent string of wet months can be largely attributed to a negative Indian Ocean Dipole (IOD), which increases the amount of moisture moving over Australia from the Indian Ocean at this time of year.
This negative IOD is still active and should continue to enhance rainfall across southern Australia during the remainder of spring. So, don't pack the umbrella away just yet.
