Brisbane Metro in February 2014: Dry, warm days and average nights

February was record dry for many sites in the Brisbane metropolitan area. Daytime temperatures were above average, whilst overnight temperatures were close to average.

Rainfall

It was exceptionally dry in February in the Brisbane metropolitan area. Five out of six metropolitan stations had their lowest February rainfall on record. These included ^Brisbane City, ^Brisbane Airport, Archerfield, Amberley and Logan City. ^Brisbane City has recorded its lowest February rainfall, using 152 years of available February data. NOTE: Brisbane City had a monthly total of 14.7 mm in 1859 - this has been excluded due to multi-day accumulations and effects of evaporation on the total.

^Brisbane Airport had its lowest February rainfall in 64 years. The western metropolitan sites of Archerfield and Amberley had the lowest February rainfall in 84 years and 73 years respectively. All five stations that recorded their lowest February rainfall on record received less than 15% of the historical average (see table below).

The wettest single day was at Redcliffe with 15.8 mm on the 18th, due to thunderstorm activity over the metropolitan area.

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 1 pm on Monday 3 March 2014. 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.

The ACORN-SAT dataset is being used for temperature area averages from December 2012 onwards. The major change from earlier datasets is that the ACORN-SAT dataset commences in 1910, rather than 1950, and hence rankings are calculated using a larger set of years.
