The Territory in 2007

Summary

Overall, the Territory had an above average rainfall year in 2007, and was slightly warmer than normal. This is in contrast with much of southern Australia, where large parts experienced generally dry and hot conditions. Heavy rain that fell in a persistent monsoon event during February and March contributed to widespread flooding at the time, and parts of Arnhem Land and Kakadu had their wettest year on record. In general much of the Territory was well served with rainfall during the early part of the year. The Territory then experienced it's coldest June on record, when a cloud band overlaying cool air also gave large winter rainfall to central parts of the Territory. In early December a hot-spell saw new hot day and night temperature records established across a large area.

The torrid beginning to December over the Top End ended when the North Australian Monsoon set in around Christmas time, giving much of the Top End widespread rainfall.


Rainfall

The average rainfall over the Territory was 643 mm, being 96 mm above average.

The wettest overall was 2623.4 mm at Jabiru Airport. The record high rainfall at Jabiru is largely attributed to a remarkable monsoon event in February/March, and is one of the largest inland Top End annual rainfall totals ever recorded.

The driest overall was 147.6 mm at Kulgera.

The wettest single day was on 4 March when Wudikapildiyerr recorded 410.8 mm, followed by 393.4 mm at Jabiru Airport on 2 Mar. 

Some sites had their highest total rainfall on record.


Maximum temperature

Overall maximum temperatures were slightly warmer than normal. The area-averaged maximum temperature across the Territory for the year was 32.3°C, which is 0.39°C above average, and the 26th warmest year (73rd coolest) since records were established in 1910. In general most northern areas were close to average, while much of the Alice Springs district was 0.5 to 1.0°C above average.

The hottest day was 46.5°C at Elliott on 2 Dec, followed by 46.0°C at Ali Curung on 2 Dec.

The warmest days on average were 35.1°C at Bradshaw and Timber Creek.

The coolest days on average were 28.6°C at Arltunga, followed by 29.1°C at Kulgera.

Notes

This statement has been prepared based on information available at 11am on Thursday 3 January 2008.
Some checks have been made on the data, but it is possible that results will change as new information becomes available.

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, normal in decile 4 to 7, high in decile 8 or 9 and very high is in decile 10).
The Fraction of normal shows how much rain has fallen this time as a percentage of the long-term mean.
