Annual Climate Summary 2010

The Annual Climate Summary 2010 documents the many climate extremes and contrasts experienced in Australia last year. Now available on the Bureau's website, the 20-page summary describes climate conditions and analyses key statistics for the year against longer term patterns.

The Summary shows that 2010 was significant for its heavy rainfall during the second half of the year, along with the strong La Niña event in the Pacific, record high sea surface temperatures near Australia, widespread flooding and continued global sea level rise.

Inflow to Lake Eppalock in Victoria's Campaspe Basin was nearly 30 times the average and four and a half times the highest volume ever recorded for November to January.

Recent and historical data for 21 sites in the south east Murray-Darling Basin are a key feature of the Bureau's new Seasonal Streamflow Forecasting Service. Recorded streamflows are plotted against the forecast and show the inflow for the past 12 months compared to the historical record for those months. This is shown as a traditional box and whisker plot.

The Bureau is proposing changes to each of the nine data categories in the Water Regulations 2008.

The metadata detail required to accompany each observation (data file) is proposed to change significantly. A draft list has been drawn up for Category 1a Watercourse level that features 35 metadata elements. The Bureau expects to draft metadata lists for all Regulations subcategories over the coming two years.
