February Rainfall

Two rainfall events produced some significant daily totals; overnight on the 6th February and then during the 15th and 16th February.  Totals varied, but produced large falls in all metro sites.  Brisbane Aero was the driest metro site for February, where the site recorded 90 mm for February, missing out on the substantial totals recorded in the other metro sites.

Redcliffe had a blocked rain gauge on the 16th, producing an incorrect daily total on the 17th (60 – 80 mm was recorded in the area). Amberley recorded no reading to 9am on the 16th, despite 90 – 100 mm falling in the area. 

The wettest overall was 319.1 mm at Logan City Water Treatment, and the wettest single day was 128 mm, also at Logan City Water Treatment on the 7th.

Notes

A Monthly Climate Summary is prepared to list the main features of the weather in Brisbane Metro 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 Monday 1 March 2010. 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 9 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.
