When you click on the ABC link the story is slightly different but same old same old Scientists on ‘strangest continent’ Antarctica investigate effect of climate change on animals – why refer to Antarctica as “strange” ?
This article got my curiosity too – Reality sinks in for flood-affected families in Deception Bay – the big question is asked – “…will this happen again?”
I do wonder about our education system.
The GreenLeft have been hyperventilating at the ABC over this too – NT deep sea port in environmentally significant area open for business despite no impact assessment – disgusting!! and the world has not ended?
Fairfax are running this story Brisbane weather: Wettest May day in 175 years
The claim that 182.6mm on the 2nd May represents the “Wettest May day in 175 years” is not even technically clean because many early years had no data – so the 175 years is shonky. But let’s ignore that. Facts are that rain data are so noisy that any claims based on one station need examining. In this case on 2nd May 2015 for the BoM’s own rain district 40 South Coast Moreton & Brisbane.
These stations exceeded the 182.6mm figure. I have tried to avoid the higher altitude stations which have heavier falls.
ALDERLEY (040224) 252.4mm
BEERBURRUM FOREST STATION (040284) 233.2mm
BOONDALL (040531) 213.6mm
CALAMVALE ALERT (040784) 186mm
DECEPTION BAY ALERT (040980) 278mm
HILLTOP GARDENS (040911) 209mm
MORAYFIELD ALERT (040979) 296mm
PEACHESTER (040169) 269mm
TOMEWIN TALLOWOOD (040899) 187.4mm
WATERFORD ALERT (040878) 193mm
Let’s look at a four day period 2nd to 5th May 1996 – there may be others but my time is limited –
I think by any standards the 2nd to 5th May 1996 swamps any record claimed from 2nd May 2015. Count some of the 4 day totals.
More likely a once in two years event. Queensland storm: Five dead in storm called ‘one-in-2000-year event’
I saw this headline – Thats why our homes flooded
Queensland storm: Residents of Deception Bay claim Moreton Bay Rail Link works contributed to homes being flooded
Interesting to read the comments in both articles – most seen realistic.
I was surprised to see on TV news video of quite modern houses built along what became a raging watercourse. Looks like Qld town planners need to learn basics about flood prone areas.
Fairfax media reports – Brisbane weather: ‘An extreme weather event’ takes five lives – The ABC reports – Queensland weather: Five people killed after three cars swept away by floodwaters; storm moves into northern NSW –
A BoM contour map shows the rainfall to 9am on 2nd May – this map is for 20 May 2009 – note the higher rain contouring into the purple zone.
The 7th, 8th and 9th of May 1980 had heavy rain in the Brisbane region too. Note I have only scanned for May rain – there would be many more floods if I looked at all months.
I have not yet seen numbers convincing me that the last couple of days was worse than 2009 – and daily data is very poor for the earlier in the 20th Century.
There are many more rain gauges now but data is not easy to access. This AWN site is useful for eyeballing daily rain at the many Brisbane region stations. Here are the rain maps from above BoM links to compare for yourself –
Purple is above 200mm per day
Dark blue is 150-200
Light blue 100-150.
Obviously the station data is more spotty than the contour maps – and BoM computing has to somehow average to get the contour positions.
First let me say I am not in any way against the clearing of whatever trees have to be cleared for the new BoM weather station. Australia has no shortage of trees or places to replace a few.
I am simply pointing out the utter hypocrisy in classifying these trees so nitpickingly adversely – see extract from Adelaide Park Lands Authority Agenda – page 60/143.
Not significant – atypical in form – low vitality – poor structure – regrowth – and low life expectancy – pass me that chainsaw quick.
The photo shows ordinary enough mallee struggling to establish itself a bit of a habitat. If a mineral exploration company wanted to say clear 18 trees like this for a drilling program – hundreds of km from anywhere at Outer Black Stump – they would expect to have to lodge a Review of Environmental Factors or REF report – probably running to many dozen pages and usually requiring a consultant costing up to or over $10,000. They would also have lodged upwards of $10,000 as an environmental bond to have an exploration licence granted in the first place – to ensure that the site was rehabilitated.
All this before your drill bit touches soil. In the case of a REF there would have to be assessments of fauna too which the BoM seems to be escaping in this case, yet there must be birds and insects inhabiting these trees.
How wrong I was – the weather instruments are just on a lawn in a commercial area – see pink X – the parklands near Norwood start in bottom left.
This is additional to the post on 11 April 2015 commenting on Fairfax media reports that the Kent Town site has to close in July due to lease running out and the BoM are relocating back onto parklands near the original West Terrace site. I am hoping somebody from Adelaide can send me photos of the new site.
Just found this 26 Mar 2015 Agenda of the Adelaide Park Lands Authority – 14MB pdf. See pages 54-88incl – lots of fascinating information and nuances piled on politically correct nuances.
Anyway – this aerial map sets out the essence.
Would still appreciate any photos of activity at the site.
Despite these fascinating curves in the continental cloud bands
