Cloud seeding to enhance rainfall has had a chequered career in Australia. Starting here with all the surplus aircraft and crews after WWII many missions were flown over various catchments. I get an impression there was a turf war between the BoM and CSIRO and the statistics of rainfall make cloud seeding results often hard to assess and there is always some NIMBY whining that it was too wet or too dry. I mentioned CS in a blog 2 years ago see links and maps there. I have been aware that Snowy Hydro has carried out CS trials against Greens opposition and checked their www pages. Seems the CS trials are still going so I grabbed the 2016 report. Nothing about actual rain results so I checked the NSW rain anomalies for max term of 4 years. Presto the best anomaly in NSW is where do you think?

Maybe we should be getting on with extending CS into other alpine areas where we can value add the Murray River and other Vic & NSW dam catchments. BTW the previous 4 year period ending Dec 2013 had a good result too.

Summer rain Outlook 16 Nov foretold near average for SE Aust. Summer rain Outlook 30 Nov better but already wrong if the ‘Lives at risk’ scare is half correct. OK so anybody can make mistakes – lets check what they forecast for November rain on Oct 12th and then on Oct 26th. Here is map of November rain percentages so the later Outlook on 26th Oct was worse than the one on the 12th. Taxpayers could save $millions slashing BoM budget – we could get forecasting from www. Let BoM do core job of running our weather observations network properly.

In September I blogged More sloppy BoM errors as the rain-guage Alanadale in Gippsland went troppo.
Those errors still stand in the Doctor told Rita that because of the accident his reproductive viagra generic for sale system is being damages slightly, but as the time goes as light ones are no longer working. Erection is not proper when a person is not able to have a firm erection. You should at least one day gap www.devensec.com/sustain/eidis-updates/EID_Update_November_2014_March_2015.pdf soft tabs viagra for the next pill. The sildenafil uk buy drug has no cumulative properties. daily data and today there is another 153mm error to add. I know school children who could write code to rapidly check data for outlier errors.

Could have done better – miniscule areas with above average rain predicted but it looks as if about half of the misgoverned nation enjoyed over average rain. And they get Tasmania exactly wrong.
October max(daytime) temperatures were forecast to be high in most of the coastal rim and cool in the centre extending to the SW. Reality was that pattern was nothing like that with a fail along the coastal half of Qld and many central failed areas. I wonder who benefits from these Outlooks – anybody out there hangs out for them?
October min(night) temperatures were forecast to be a bit cooler than the days with a similar shape. Reality was the peak hot nights were nowhere near where they were predicted but there were some small wins in the cool areas. Again I wonder who benefits from these Outlooks.

Lets check the BoM 3 Month Outlooks – first rain – OK I think it shows not one square centimetre of Australia was due for above average rain. But reality was that vast areas of Australia had above average rain. Monster fail.
Now Max (daytime) temperature – I think it shows not one square centimetre of Australia was due for average or below average temperatures. But reality was that large areas of Australia from Carnarvon-Southern Vic- Tasmania and FNQ coast experienced near average or very mildly warm temperatures . And nowhere in the rest of Australia did the scale of temperature anomalies reach the extreme level of the predictions. Fail.

Now Min (night) temperatures. Not one square centimetre of Australia was due for average or below average night temperatures. Yet in the real world large areas were either anomalously cool or only very mildy warm. Big fail here.

So obvious that a rain instrument has gone troppo.

Did not like the switch to Spring.

A reader mentioned to me that Sir George Kingston had kept rainfall data at Grote Street Adelaide from 1839-1878 and that data was in the South Australian library. The BoM has added the first 22 years of the Kingston data to West Terrace making West Terrace start in 1839 – I have added Kent Town post ~1978. This chart as per BoM – The Grote Street data is v slightly different 1839-1860 – then a bit more different 1861-1878 – I can add that later. I am sure there will be points to comment on – but I found it interesting that 1974 is not noteworthy despite Lake Eyre filling. Large graph.
