Northern Territory in November 2007


Summary

Afternoon storms were a feature of November 2007 in Darwin, with rainfall recorded on 21 days during the month. This was the second-highest number of rain days ever recorded in November at the Darwin Airport site, with only November 2001 recording more (22 days). Despite the high number of rain days, the rainfall total was close to the long-term average, though some rainfall-recoding sites nearby recorded considerably more; Pinelands and Nightcliff both reported 270 mm or more. Cooler than normal temperatures prevailed over most of the southern parts of the territory while temperatures around the Top End remained close to mean conditions.


Rainfall

The northern half of the Victoria River region experienced well-below normal rainfall, while further south, much of the western half saw above-average totals fall during the passage of several cloud-band features. Most of the Top End also recorded average to above average rainfall. The eastern half of the Alice Springs region and much of the Barkly district recorded average to below average falls.

Some sites had their highest total November rainfall on record.

Some sites had their highest daily November rainfall on record.


Temperature

Maximum temperatures were cooler than normal over the southern half of the Territory, and close to average over most of the northern half. There was a region around the McArthur river area that was more than one degree above average, putting much of this region into its top 10 percent of temperature records. Minimum temperatures were cooler than normal over most areas south of the Top End.

Some sites had their highest November mean daily maximum temperature on record.

Some sites had their coldest November day (lowest maximum temperature) on record.

Notes

This statement has been prepared based on information available at 11 am on Tuesday 4 December 2007. 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.
