Long lost forgotten rain bombs — the BoM yells “unprecedented” while ignoring 120 years of history

If Climate Change was a real threat, the Bureau of Meteorology might even look at their own historic records.

When Jennifer Marohasy and Chris Gillham did just that, they found that as bad as the current situation is, it’s happened before:

  • The wettest day in Lismore was in February 1954.
  • The wettest year for Lismore was 1893.
  • There was no increase in the intensity or frequency of extreme wet days at Lismore, or the towns around it.

Now if the BOM looks at this with a supercomputer, they might find an effect from CO2. But if the BOM just used a calendar, like I did, they might find the latest floods started the week after Hunga Tonga volcanic dust rolled across Australia. Maybe that matters?

No one needed a supercomputer to read a rain gauge in 1885, and we have excellent long data. Imagine how handy that might be if the BoM wanted to understand, say, Australian flood cycles?  There are 137 years of rainfall records in Lismore from 1885 to now, but the BOM said we set a new record for Lismore based on Lismore airport where records started as long ago as… 2002.

 

The Bureau of Meteorology is guilty of exploiting taxpayers, vandalizing Australian history, and spitting on decades of work by the earliest meteorologists in Australia. And they want us to think they care?

Here’s what big rain looks like in Lismore:

Like it happens all the time.

Australia has always had floods and rain bombs.

Well done to Chris Gillham for his help at WAClimateNet.

    Dave of Gold Coast, Qld.

    Thanks Jo, at least someone still has a brain not linked to the climate change mantra. One should also consider Lismore’s physical placement in relation to the Richmond River. That river has always been prone to flooding and has a very steep catchment area. Most towns and cities were built on rivers for the access to water supplies and Lismore is one of the most vulnerable ones. Why people continue to build in flood prone areas puzzles me. Then they and the politicians cry for government help every few years. Australians suffer from this world wide problem… “One thing we learn from history is that we never learn anything from history!”

    There is a greenhouse gas effect, water vapour increases by roughly 7% more per 1°C of warming. Overlaying this are decadal weather patterns and long-run climate changes in rainfall distribution. Single site attribution is going to be difficult.

            So when will the ABC, BBC, BOM start to be honest about that Simon and Peter, or don’t you care if they continually misrepresent the floods as “climate change” when there is no evidence at all that they are.

            And it’s not OK if the mainstream media just finds some activist librarian of Nowehereville to interview and say “it’s climate change” — if the BOM and “experts” don’t admonish and correct the media for perpetrating a scientific lie.

        Climate is not linear, its a highly complex system.

        Do volcanic eruptions cause rain bombs? Did the 1893 eruption in South America impact Lismore?

        ‘One of the largest historical eruptions in southern Chile took place from Calbuco in 1893-1894. Violent eruptions ejected 30-cm bombs to distances of 8 km from the crater …’ (Smithsonian)

        It was a fairly long lived eruption and smoke had a chance to reach Australia, depending on the season and what the jetstream was doing.

          It’s not just Lismore in 1893, but the a similar area of the east coast to this last burst. 1893 Beaudesert received 1726mm, 85% above average 932mm, 674mm of it in February, the wettest to date in measured rainfall.

          Next comes 1954, with 1457mm, again with 550mm in February. This year fits in well here, with 619mm, again in February. Interesting that each of these events were about 60 years apart. I wonder if that has any significance. We may know in 2075 or so.

            If we travel further back another 60 years we see that 1829, 1830, 1831 and 1836 were all wet in South East Australia. So presumably La Nina and a negative PDO, coupled with a positive SAM, must have happened at that time.

            Three consecutive La Nina are clear to see and a period of severe drought followed in the latter 1830s.

        Yes “Peter Fitzroy ” Simon nailed his green colors to the mast again and loves his greenhouse gobble talking points ….The La Nina weather anomaly compounded by the Tonga Hunga volcanic dust and aerosol cloud passing over Australia had nothing to do with the precipitation dumps and floods that followed within a few days .It was just an extraordinary coincidence …A perceptual selection effect ! All that sulfate and water vapor pumped into the stratosphere by that huge Pacific undersea eruption must have magically disappeared somewhere ..I still remember the summer downpours in Victoria that followed the Mt.

          The last 7,000 years has seen oceans drop by between 6
          to 4.2 metres in total.

          That’s a very strong pointer to the idea that the polar caps are holding on to the rain and snow and storing more Ice.

          Of that sea level Fall, 1.2 metres of it was in the last 2,000 years and in my lifetime there’s been no significant movement either way.

      H2O is the only gas that can alter the rate of net radiative transfer in the atmosphere.

      It is nothing to do with CO2.

      Historical data shows no trend in severe rain events on the north coast of NSW.

      Why is that so hard for you to grasp !

      Your simplistic lack of understanding of basically everything, and your total lack of data to back up anything nonsense you sprout, makes you look like nothing but a religious zealot.

      And that’s why the system sorts itself out. Eventually, saturation occurs, clouds form and that starts a cooling process as sunlight is reflected back to space. Clouds are the big unknown in all climate models, and cloudiness or the lack thereof seems to be a far more important variable in determining global temperatures than the chemical composition of the atmosphere. Doubling CO2 might raise the temperature by 1 deg C, doubling Cloud cover would probably result in an Ice Age.

      Hi Simon

      You say “water vapour increases by roughly 7% more per 1°C of warming.” and ” Single site attribution is going to be difficult.”
      But this is not just a single site. The same pattern of more rain and floods in the past and decreasing extreme rain and decreasing floods is seen at MANY sites in eastern Australia, especially SE Qld. This rain event was not unusual (see https://kenskingdom.wordpress.com/2022/03/03/how-unusual-is-all-this-rain-weve-had/) and Australia’s natural disasters are not getting worse (see https://kenskingdom.wordpress.com/2022/03/23/is-australia-getting-harder-to-live-in/).

      In Perth, it has been a hot summer but we’ve had many very mild ones in the lead up to this one. We also experienced very heavy rainfalls in mid 2021 which gave us well above average rainfall for winter. So, what do I hear a BOM spokesperson say today? She pointed out that we’ve had a very dry hot summer. “Could also be the hottest Autumn if this warm weather continues” she says.
      Our fruit growers were complaining that without backpackers being allowed into WA, they couldn’t find workers to pick cherries. I know some champion cherry-pickers at our Bureau of Meteorology that surely could help.

    Very confusing graph – I read it a single days above the 99th percentile, which is a thunderstorm (admittedly an big one).

    What we saw in Lismore’s various catchments was 6 or more days of heavy rain, producing the 2 flood events. These are now called rain bombs.

    I note that there is no mention of such an event (2 500 year in a month) – which makes that unprecedented.

      Peter Fitzroy,

      Very confusing graph

      Rather than confusing, I’d say it’s weird: the annual total rainfall of just the really wet days. So a big spike in this graph might be due to big downpours 11 months apart wuth neither being a flood. OTOH, there’d be no spike at all for a long run of not quite 99th percentile wet days.

      If I wanted to show how flood-prone weather has trended/not trended, I’d plot something like a rolling 30 day total rainfall throughout the record. To come up with a year-by-year summary you could just choose the maximum 30-day total from each year. Obviously I plucked 30 days out of the air. Maybe it should be 7, or 50.

              The staggering scale of the 1974 rainfall totals are still a record in the BoM Australian nationwide rainfall series since 1900 ….Australia’s worst bushfires followed in the summer months of 74-75 burning 117 million hectares of the continent.

      I’d say that compared to a normal time you would call more than two flood events. There were two record breaking flood events, piled on top of a number of lesser floods.

      In the last 60 years locally there were two storms which caused spectacular flooding, one called at more than six inches, the other at up to ten inches, which gave us three inches as it wound down.

      Neither registered anywhere near those figures on an official gauge, but the floods they generated make those numbers feasible.

      Intuition tells me I haven’t in that time seen much above half a dozen events where three inches registered in 24 hrs.

        G’day Ted1,
        I’ve only been out here for 30 years. The previous owners measured 10 inches from an overnight storm a couple of months before we arrived, there was one more a few years later, but my heaviest rain was three and three quarters inches in just under an hour. The latter ripped the guts out of the laneway to my front gate and it took several weeks of our and neighbours’ work to get the laneway back to normal use.
        All of those storms were local, and missed the official gauge at Mudgee airport, about 25 kms away.
        Another indicator of variability of rainfall: A neighbour about 2 kms to my west and I are separated by a low ridge. On several occasions we’ve compared numbers and he’s had an inch more than I’ve had from the “same” fall.

        As far as I can tell, the “official” figures can only be considered to be better than nothing, and at least provide a consistency of location and recording.
        Cheers

      The entire Northern Rivers District is in the much-eroded caldera of an ancient “super-volcano”.

      This thing chucked a lot of big rocks a long way and the pyroclastic flows extended past Ipswich in Queensland. You can walk past the welded ash beds (Tuff) in White Rock Park, near “Spring Mountain”. Welded Tuff: Fine volcanic ejecta that was so hot when it was blown out in huge pyroclastic flows, that it fused to the previous deposits and became “interesting rock formations” covering tens of thousands of hectares.

      The SAME rock was used in a large amount of civil construction in Brisbane’s early years.

      Australia was once extremely geologically active, especially along the”east coast”; Glasshouse Mountains? Heavily-eroded volcanic “plugs.In the north there are the crater lakes on the Atherton Tableland and the impressive Undara lava tunnels. The planet is a seriously dynamic system; Get used to it.

        Strongly disagree, if we look at the 60 and 30 year cycles the picture becomes clearer.

        ‘We compared our historical rainfall data to previous El Niño/La Niña events and found a weakening in the relationship during 1920–1940 and 1835–1850. The breakdown was especially clear in data from the southern part of our study region. This is the first time the 19th-century breakdown has been seen in Australia using instrumental data.

        ‘Of course, the next question is why? Why does the impact of El Niño and La Niña on Australian rainfall change over time? What happened in the mid-1800s? It might be El Niño’s cranky uncle, the Interdecadal Pacific Oscillation, or perhaps strange behaviour in the atmosphere around Antarctica.

              there are cycles, and that is a given, and if there was no anthropogenic changes to the the composition of the atmosphere it would be both reasonable and logical to assume that yes – the past is a good predictor of the future. However, man is changing the climate, on a small scale with UHI and on a larger scale with GHG’s soot, etc etc.

              What the models forecast is the increase in the amplitude for the cycles something which is seen now with the el nino’s not being as cold as previously.

                “man is changing the climate”

                Again with the unsupportable anti-science. !

                Only GHG that can effect weather, is H2O ….. There is no evidence that CO2 has any effect whatsoever, (as you have repeatedly show)

                Man has basically zero effect on the global climate.

                El Ninos used to be a lot warmer only a 1000 years ago. We just happen to be coming out of the coldest period in 10,000 years..
                A really stupid period to choose to compare things to.. But its all the AGW hoaxers have.

                Choose a model that forecasts something, then another that forecasts something else.
                So many models so many conflicting “predictions”
                None of them correct except by pure chance.. !

    Note above at the graph for heavy rainfall days and then ask yourselves how there were two recent very dry periods in 1990s and after 2000.
    These periods are very obvious and again proves these higher co2 level periods are not connected to just high rainfall events.
    IOW we can have these very recent decades that have multiple years of lower rainfall and higher rainfall events.
    I think ENSO would be the reason and ongoing el nino or la nina events seem to be the best explanation.
    BTW co2 levels in 1992 were about 356 ppm and in 2012 about 394 ppm. But the Hunga Tonga volcano event will certainly require more research as well.

      I suppose we should also remind everyone that co2 levels in 1900 were about 296 ppm and about 304 ppm in 1920.
      In that period there were more gaps in the Lismore higher rainfall events. But previously from about 1880s to late 1890s there were higher rainfall events when co2 levels were lower than 295 ppm.
      Certainly nothing to show that co2 levels have made a difference at all.

        Ian:
        The Global Average Surface Temperature is 14.0, 14.5. 15.0. 15.2 all in Celsius and depending on who did the guessing.
        Satellite measurements are supposedly more accurate but only measure about 80% of the surface. That’s better than the figure for 1855 – 1857, which is based on ONE thermometer for the whole of the southern hemisphere in what is now Indonesia (and for the next 5 years on 3 only as Sydney & Melbourne were added).

        There is an alternative conversion method – Add 40 to the temperature reading, then multiply by 9 and divide by 5, then take off 40. For Fahrenheit to Celsius just reverse the calculation. It may sound silly but it works and is based on minus 40 being the same temperature in both scales.

    Back in the day when they had proper schools (not indoctrination centres) one of the topics taught was “geography”. That included the topic of flood plains which people used to know about.

      I suspect you’ve not had too much interaction with modern kids. They use the internet a lot admittedly primarily to play endless games with hordes of like minded friends but also to gather information

      Take flood plains. Wikipedia says

      A floodplain or flood plain or bottomlands[1] is an area of land adjacent to a river which stretches from the banks of its channel to the base of the enclosing valley walls, and which experiences flooding during periods of high discharge.[2] The soils usually consist of clays, silts, sands, and gravels deposited during floods.[3

      As you can see the language used may require help but certainly broadens their vocabulary and often leads to further searches to find out what adjacent and silt and high discharge means.

    The 7% increase in water vapour with 1 degree temp rise, is just potential. Explain the 2019 drought?
    In the video she mentions extra flood height caused by chock points. Nah. It was way above any restraining levies.
    As for the way of measuring by the 1% heaviest rain. It’s one way of illustrating. Does making it a longer period help? The Northern Rivers has been wet, wet, wet. I doubt we’ve had 14 sunny days this year? So the soils are saturated. But no one was losing any sleep about that, before the 2 day, then the later 1 night downpours. No warnings, everyone happily tucked themselves into bed those nights; if it’s wet, take an umbrella, and awoke to devastation. I totally slept through the last one. What rain? So it was those 3 very heavy nights that did the damage. Actually it might have been just 2 nights? For the big one it rained as predicted the night before, and up to lunchtime, but the rivers weren’t doing much. It stopped raining for the afternoon, so no problem, but then it really kicked in well after dark.

    So why are Humans so wealthy and healthy today and why has our global population grown so rapidly since 1800?
    In 1800 our pop reached 1 billion people, then 2 billion by 1927,then 3 billion by 1960. then 4 billion by 1974, then 5 billion by 1987, then 6 billion by 1999, then 7 billion by 2011 and today about 7.9 billion and soon 8 billion by 2023.
    Yet the rate of global pop growth has DECLINED since about 1968, although a very young African pop ( about 19 years) has ensured a much more rapid growth in that continent since 1970.
    But the Malthusian donkeys plus some of the kiddies etc all tell us we are living in the end times and are facing a Climate CRISIS or EXISTENTIAL THREAT etc.
    AOC and Biden, UN, UK, EU, plus Aussie donkeys etc think we only have a few years left before we face the apocalypse and we’ll all be punished for our sins.
    So how come we now have a global life expectancy of about 73 today and increasing wealth and YET we’re supposed to fall over the precipice in just a few years time? Any ideas, anyone?

        I agree with all that Ian, so where does their EXISTENTIAL threat fit into their apocalyptic forecasts?
        And Africa has increased their population nearly 4 fold since 1970 and yet they now are better off and their life exp has increased from 46 years then to about 63 yrs today.
        And that 63 years is now higher than the global average was in 1970. And Africa had to suffer from the HIV/AIDs disaster over the last 40+ years as well.
        The climate has been very beneficial for a very long time and deaths from extreme weather events have also dropped by 97% over the last 100 years.

    And one that the BOM don’t have.

    The main creek drainage for the area goes through our property and is joined by a smaller creek just to the south of the site of one grandfather’s homestead.

    According to district rain gauges there was nothing outstanding about the rainfall for the area in May 1917.

    However Grandfather arose one morning in that May to the sight of the main creek channel running uphill from water from that smaller creek. He headed for the next homestead south in time to swim the occupants off the roof of the house.

    At a homestead on that smaller creek a kerosene tin bucket that was empty the night before had overflowed during the night. I found one and they’re about 14 inches high.

    Hasn’t happened again as yet but residual sandbanks suggest there has been a lot of water around here in the past than in European experience. I am reminded of the paleo floods mentioned by Geoff Pickup from CSIRO Alice Springs.

    Some fun facts regarding floods in Australia.
    In 1810 Governor Macquarie proclaimed 5 new towns on the high ground along the Nepean and Hawksbury rivers. However settlers on the flood plains refused to move. In 1817 he wrote to the Earl of Bathhurst, frustrated that settlers would not relocate their families and livestock one mile from the flood plain. He noted that farmers had “infatuated obstinacy in persisting to reside with their families, flocks, herds and grain on those spots subject to flood” And as a result “they have often had their prosperity swept away.”

    In 1851 Bega floods killed 17 residents and it was estimated that the town site was covered by 9 meters of water and extensive damage was done to crops.
    The town of Bega moved to its current location.

    In 1852 Gundagai relocated after 89 people drowned from a population of 250. Originally it was located between 2 rivers.
    In 1916, Clermont ( QLD) was relocated after 64 people drowned in an unexpected flood.

    In 2012 Grantham did a land swap after 2011 floods , it is expected that 70-80% of residents will move to the new town.
