The Wacky World of Weather Stations: No. 81- Brewarrina (NSW)

Please refer back to my first post for site specifications.

In 2002 the screen was moved “as a temporary measure” to its current position 17 years later, when a new nurses’ accommodation was built right beside it:

Site plans also show how nearby trees have grown, been trimmed, and removed over the years.

Not as bad as some, but the screen is within 10 metres of a building and concrete path, 20 metres from a levee bank, and the presence of “lawn” in the dry outback indicates the area has been at times watered.  As well, the station has changed substantially over the years.

This station is non-compliant, with temperatures reported at Latest Weather Observations and used to adjust data at Acorn sites.

    I wonder how high the levy bank is Ken ? It would significantly block winds from the North West ( ? ) And that would have an effect on temperatures registered on the BOM weather gear.

    Meanwhile Wikipedia states this about Brewarrina’s climate : “Brewarrina has the typical hot semi-arid climate of north-western New South Wales, with hot summers frequently over 40 °C (104 °F), cool winters and generally dry all year round. Brewarrina’s highest recorded temperature was 48.9 °C (120.0 °F) on the 19 December 1912, whilst its coldest was −4.1 °C (24.6 °F) on the 14 July 1997. The average annual rainfall is 412.2 mm (16.2 in).”

    It’s interesting that it’s hottest temperature was in 1912, ( 48.9 degrees ! ) and that it’s coldest was in 1997 ( -4.1 degrees. )

    Restricting the natural wind flow with the new nurses accomodation and the levy bank ( neither of which existed in 1912 ) should tend to produce hotter temps on the BOM thermometer. But that has not yet happened !

    Puzzling !
