Weird Weather

It seems utterly bizarre to think of anything other than the usual rain, hail and snow falling out of the sky, but there are many official reports from all over the world of showers of a different kind and acknowledged as weather phenomena. Showers of Frogs and Tadpoles are the most common sightings from around the world. For instance, on the afternoon of June 16th 1939, thousands of frogs fell over Trowbridge, England. Strange showers are more common than you’d think. Throughout history there have been persistent stories of showers of things falling out of the sky, from the time of manna to feed the Israelites in the Sinai Desert to the present day. In AD 77 in Greece there was a continuous shower of fish for three days and Pliny the Elder recorded – “…the roads were blocked, people were unable to open their front doors and the town stank for weeks …” Experts have tried to dismiss eyewitness accounts such as the fall of fish on Dunmarra, south of Darwin in February 1994 and a fish shower in Markville, USA on 23 October 1947 that was witnessed by a US Dept. of Wildlife and Fisheries Officer. Some other things falling from the skies phenomena include:- Hazelnuts in Dublin in 1867 Snails in Chester, Pennsylvania in 1870 Snails in Algiers in 1973 Crayfish across Florida in 1954 Maggots in Mexico in 1968 Pond mussels in Paderborn, Germany in1892 Jellyfish in Bath, England in 1894 Coal in Bournemouth England in 1983….. In most cases these phenomena occurred when there were severe thunderstorms about. Thunderstorms with updrafts strong enough to suck up anything light enough underneath to be picked up and taken aloft and deposited elsewhere. But what about when we say ‘it’s been raining cats and dogs’? How do you think this saying originated? In my research I found many theories. I think the best answer maybe the one originated in the filthy streets of 17th/18th century England when heavy rain flowing down the gutters would occasionally carry along dead animals and other debris. Animals didn’t fall from the sky, but the sight of dead cats and dogs floating by in heavy storms could easily have coined this colourful phrase. Jonathan Swift described such an event in his satirical poem ‘A Description of a City Shower’ 1710. Another saying when we describe torrential rain is “It’s Coming Down in Stair Rods”‘. How did you think this saying originate? Any suggestions?

Heard this one before? Eleven little black spiders were playing in a saucer with a tiny ball. After a short time the coach, a much bigger spider, standing on the rim of the saucer blue his whistle. “Gather round – boys”, he said, “You’ll have to do a lot better than this next week – you are playing in the Cup”

The reluctance of the high stationery in the southern Coral Sea to drift eastward brought hot north-westerly winds to the Ranges and a state of extreme fire danger. The stable atmosphere that persisted for most of September showed little likelihood of breaking up until 9.30pm on Saturday. This was when winds backed to south-east, bringing in moist maritime clouds and the splatter of a few rain drops, possibly from some virga that reached the ground before evaporating.

 September Round-up

This is the time of year when our eyes scan the horizon seeking the first sign of buds bursting out in colour on jacarandas trees. The heavy scent of jasmine and freesia fills the air, joy to some and an allergy to others.

 

Throughout the month a persistent high pressure system centred in the southern Coral Sea showed a marked reluctance to either weaken or drift eastwards blocking the likelihood of any substantial precipitation reaching us in frontal systems approaching from the south.  The result was we have had the lowest monthly rainfall for six years measuring only 39.4 mm, representing 24 mm below the 116 year average. The season’s first thunderstorm was an isolated cell on Monday 7th   this brought 29 mm of rain to help fill near empty tanks on some properties. Total rainfall for the first nine months of this year is on track with the all time average.

 

It’s been a month of high fire danger brought on by tinder dry undergrowth, strong winds, 116 mm of evapotranspiration,  solar radiation over 1000 watts per m2 , low relative humidity and 231 hours of bright sunshine. This recipe for a major disaster was averted only by the skill and expertise of our local fire-fighters.

 

The major phenomena of the month was the widespread dust that twice covered the east coast of Australia from Sydney northwards, arriving on the Blackall Ranges on Wednesday 23rd and Sunday 27th.

 

 

 It all started on Monday 21st when an intensive low of 960hPa developed in The Bight. A cold surface trough associated with this system moved across Victoria and into NSW and SE Queensland.  Overhead instability of the atmosphere was intensified by troughs in a NW cloudband. On Wednesday we had hot gale force winds whipping up red top soil from out west, including silt possibly from Lake Eyre, and then depositing some 75,000 tonnes an hour of dust along the east coast. Sydney airport closed early in the day and planes diverted to Brisbane. On the Blackall ranges the day started with a slight haze.  At 1.15 pm winds backed to SSW and widespread dust moved in dramatically dropping visibility to 300m. The wide spread  dust cleared the region by the following afternoon and made Thursday a day of mopping-up grit that had penetrated everywhere. Vehicles needed cleaning, also air conditioner filters. Washing machines were kept busy. 

Pollution count was the highest on record with 15,000 micrograms per cubic metre, whereas the norm is 20 micrograms. A normal bush fire records about 500 micrograms a cubic metre.

The second phenomena occurred on Saturday evening 26th. .At 9.00pm wind backed to southwest bringing in once again widespread dust to the region. On this occasion the dust was less dense due to lighter winds and less noticeable during hours of darkness.

Sumatra Earthquake

The US Geological Survey says another earthquake, measuring 6.8 on theRichter scale, has hit the Indonesian island of Sumatra.

The quake comes less than a day after a 7.6-magnitude quake in the same area, which killed hundreds of people and destroyed large parts of the region’s capital Padang.

The earlier quake struck in the early evening almost 50 kilometres off Padang, a coastal city of about 900,000 people.

Indonesian officials say they fear the death toll from the first earthquake  could soar into the thousands.

Samoa Tsunami

Over 140 people may have been killed after giant waves hit the islands’ coastlines early on Wednesday morning following an 8.3-magnitude earthquake in the ocean south-west of American Samoa.

Tsunami 30.9.2007

From the Archives

    An earthquake measuring 7.8 on the Richter scale occurred at 3.23 am on Sunday 30th September 2007 near the Aukland Islands and activated Australia’s first tsunami early warning buoy, sited on the ocean floor south of Tasmania. All coastal areas of Tasmania and New Zealand were alerted of a possible sea-level rise and flooding. The warning was cancelled early Monday morning when only minimal rise of sea-level occurred.

Dust Storm 19.12.1852

From the Archives

A dust storm occurred in the Melbourne area on Sunday 19th December when The Tmes in London reported ‘a man riding his horse on the outskirts of Melbourne was unable to see the ears of his horse due to the streaming volume of hot, stinging dust’.
