Rain and records fall - Northern Territory in June 2007

On the heels of the Territory's second hottest May on record comes the coldest June ever.

 

Details

An unusual cloudband persisted over the nothern half of the Territory mainly due to a mid-level trough bringing weather more akin to a southern winter. In addition to the cloudy skies, cool southeasterly airflow from the southern latitudes caused the temperatures to fall.

Some areas in the Victoria River District recorded highest on record rainfall with Victoria River Downs recording 96.2 mm when the previous record, during it's 114 year history, was 27.5 mm.

Notes

This statement has been prepared based on information available at 11 am on Monday 2 July 2007. Some checks have been made on the data, but it is possible that results will change as new information becomes available.

Normals are long-term means based on observations from the years 1800 to 2006. They are not shown for sites with less than 10 years of record in that time, as they cannot then be calculated reliably.
The median is sometimes more representative than the mean of "normal" 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, 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.
