Victoria in February 2011: One of the wettest on record

February of 2011 has been one of the wettest in Victoria since records began.

Victoria endured significant rainfall and flooding events during the month, with the most extreme event occurring during the afternoon of February 4 and during the following night, when the remains of ex-tropical cyclone Anthony were 'captured' by an approaching trough and moved across the State. This and the other events contributed to the state recording its  wettest February since at least 1973, and provisionally the 6th wettest on record.

Daytime maximum temperatures were below average, while overnight minimum temperatures were above average.

Australia is feeling the effects of one of the strongest La Nia events ever observed. The last time such a strong La Nia occurred was in 1973-74.

Ocean temperatures around Australia are near record high levels, and we have seen more frequent low pressure systems over Australia as well as much cloudier and more humid conditions than usual.

The very strong La Nia is the primary cause of the very wet month.

Whilst any one such event cannot be attributed to global climate change, a recent study of extreme weather events across the globe suggests that there has been an increase in the frequency of such events over recent decades, and this trend is consistent with what we expect under global climate change.

The current La Nia event is now past its peak and will continue to gradually decay during autumn. Bureau of Meteorology computer models suggest a return to more neutral conditions later in the year.

With the La Nina event weakening, rainfall across Victoria during autumn 2011 is likely to be close to normal. However ocean temperatures around Australia are still high, and so maximum and minimum temperatures are likely to be above average during autumn.

Notes

A Monthly Climate Summary is prepared to list the main features of the weather in Victoria using the most timely and accurate information available on the date of publication; it will generally not be updated. Later information, including data that has had greater opportunity for quality control, will be presented in the Monthly Weather Review, usually published in the fourth week of the month.

This statement has been prepared based on information available at 9 am on Tuesday 1 March 2011. Some checks have been made on the data, but it is possible that results will change as new information becomes available.

Averages are long-term means based on observations from all available years of record, which vary widely from site to site. They are not shown for sites with less than 10 years of record, as they cannot then be calculated reliably.
The median is sometimes more representative than the mean of long-term average rain.

The Rank indicates how rainfall this time compares with the climate record for the site, based on the decile ranking (very low rainfall is in decile 1, low in decile 2 or 3, average in decile 4 to 7, high in decile 8 or 9 and very high is in decile 10).
The Fraction of average shows how much rain has fallen this time as a percentage of the long-term mean.
