December 2011

December began with a couple of flashes and more of the same “cloudless rain” on the west coast.  First up was a circular flash from Sydney:

See : 512km Radar Loop for Sydney (Terrey Hills), 00:00 01/12/2011 to 15:00 01/12/2011 UTC

That was followed later in the afternoon by another circular flash from Albany. Read Cliffhanger’s related weather update here.

Circular flash from Albany, Dec 1, 2011

The picture below shows the clear skies on the north west coast, while the picture following it shows the radar telling a completely different story.  Again.

Dec 1, 2011 - no cloud

Broome to Exmouth apparently raining, regardless that there's not a cloud in sight

You’ll also notice in the above image that Darwin is not only sending out a strong and longer than usual beam, it also has a faint circular flash occurring.  The beams had been happening regularly since late afternoon, and all of them were directed toward the middle third of Timor.

Strong beams coming from Katherine for approximately two hours beginning about 1pm Dec 13, 2011

Spec lines, radar beams and more of the same along the Pilbara coast - Dec 13, 2011

A couple of good beams from Darwin on the 15th:

November 2011

November kicked off with a ring from Adelaide’s Buckland Park radar:

Adelaide ring, November 1, 2011

Interestingly, spectrum lines began coming from both Adelaide radars the next day  – I had not noticed any from this area prior to this time.

Nov 2, 2011 - Adelaide spectrum line

Two days later was a decent circular flash from Esperance, along with a few other bits and pieces.  The red lines in the picture below were added by me to show that the Wagga Wagga and Dampier beams while not only being synchronised, are also parallel:

Parallel beams and other odd things, Nov 4, 2011


The following day Newcastle showed a messy-looking circular flash – here’s how it looked on the loop:

See : 512km Radar Loop for Newcastle, 09:00 05/11/2011 to 23:00 05/11/2011 UTC

Sydney follows up with a ring on the 9th:

Strong ring from Sydney, Nov 9, 2011

November 14th seems to have been a day of editing out images from the WZ radar – at least it looks that way if you compare the following two shots taken at the same time:

Note the circle and beams on the Queensland coast from Rockhampton

Where are the Rockhampton spotty circle and heavy beams in the east?

Meanwhile in the west, Dampier was very busy beaming throughout the day – check it out on the loop:

See : 512km Radar Loop for Dampier, 00:00 14/11/2011 to 23:00 14/11/2011 UTC

The following day saw intense radar action from the Carnarvon to Port Hedland region in WA – only there was no weather around to justify any of it:

Why is this radar image like this? Nov 15, 2011

No cloud in the area of high radar activity. Why?

Here’s how Carnarvon looked as that radar mass was forming:

Well-defined circle of non-weather, Nov 15, 2011

It wasn’t only Carnarvon though, Exmouth, Dampier, Pt Hedland – all of them were doing it:

See : 512km Radar Loop for Carnarvon, 00:00 15/11/2011 to 23:00 15/11/2011 UTC

So while that west coast weirdness continued overnight and into the following day,  radars in other parts of Australia started acting up, starting with a spec line from Adelaide, which was visible on the national radar, and the South Australia radar: but not on the Adelaide radar.

Adelaide spectrum line - Nov 16, 2011

Adelaide spec line visible on SA map - Nov 16, 2011

So why isn't it in this shot? Note: 04:30 EDT = 04:00 CDT

Rockhampton circle and beams back again, along with strong beam further south from Sydney area

The Port Hedland radar imagining weather two days later:

No weather near Pt Hedland

Rockhampton dotty circle and beams are now visible on Weatherzone - Nov 18, 2011

..Still happening on both sides of the country two days later - Nov 20, 2011

And still happening the next day too:

And still again the following day. Nov 21, 2011

In the early hours of the next day, Nov 24th, Port Hedland has a sneaky circle visible:

Faint circle from Port Hedland, Nov 24, 2011

Followed later in the day by yet another discrepancy between Weatherzone and Weather Channel:

Circle clearly visible in Sydney

And clearly not visible in this screen shot

More discrepancies between radars and cloud satellite two days later on the 26th:

The cloud doesn't match the radar in the north west again - Nov 26, 2011

Look to the west of Ceduna and compare it to the next pic of the radar, Nov 26, 2011

That looks like cloud and/or rain heading toward Ceduna, but it isn't

Two days later on Nov 28th there’s no cloud on the satellite, but apparently a heap of it on the radar.  What is this, a month-long “glitch”?

Once again, no cloud visible in the Karratha to Broome area

There's that "weather" again, and a beam for good measure - Nov 28, 2011

The same thing is happening over 'the top end' - the Northern Territory with no cloud Nov 28, 2011

Mystery radar NT style (includes Alice Springs and Tennant Creek) - Nov 28, 2011

October 2011

I missed a fair chunk of radar watching this month.  However I did notice this loop from October 14th and 15th, with strong and mostly constant beams coming from Rockhampton.  There are no images available on the Rockhampton loop, so here’s how it looked as an overlay on the Emerald loop – watch for the unusual intensity at Emerald toward the end:

See : 512km Radar Loop for Emerald, 23:00 13/10/2011 to 17:00 15/10/2011 UTC

It gets even busier when you head south from there and watch the 512km loop from Namoi. It’s hard to know just where to look, but keep an eye on Newcastle as well.  Sped up to 40 frames per second makes for interesting viewing too (use the + sign in Controls):

See : 512km Radar Loop for Namoi, 23:00 13/10/2011 to 17:00 15/10/2011 UTC

Also within the same time frame was spectrum line activity from Wyndham in the north and West Takone in North West Tasmania:

Fri 14 Sat 15 (GMT)
05:00 00:00
05:50 00:10
15:40 00:30
15:50 12:50
16:00 13:00
16:10 13:10

Along with a sustained set of lines from NW Tas:
Sat 15 (GMT)

There also seemed to be an awful lot of something in Carnarvon coming from very little cloud:

See : 256km Radar Loop for Carnarvon, 16:00 14/10/2011 to 16:00 15/10/2011 UTC

As seems to also be the case from Carnarvon all the way up to Broome:

Radar showing rain but there's not a cloud in sight, October 15, 2011

No visible cloud - so what is that radar showing? October 15, 2011

In fact, from Geraldton south to Albany has the most cloud and the least radar action. Strange day indeed.

September 2011

Cairns was first up for the month with an unusual show of heavy double beams:

See : 512km Radar Loop for Cairns, 20:00 01/09/2011 to 03:00 02/09/2011 UTC

A few days later Woomera comes up with a circular flash:

A circular flash from Woomera, September 6, 2011

It was followed by an intense patch that lingered for hours:

Woomera radar acting up - September 6 2011

Here it is on the loop:

See : 256km Radar Loop for Woomera, 00:00 06/09/2011 to 01:00 07/09/2011 UTC

Two days later, this from Hobart, Tasmania:

Hobart radar September 8 2011. SuperDARN or TIGER perhaps?

The following afternoon had a pair of flashes from the Gympie radar, followed up by a heavy beam from Mackay.

Gympie radar flash, September 9 2011

Second flash from Gympie, September 9, 2011

Both Gympie flashes and the Mackay beam are visible on this loop:

See : 512km Radar Loop for Gladstone, 02:00 09/09/2011 to 15:00 09/09/2011 UTC

Tasmania fires up again with a heavy beam, it appears to come from West Takone.

A heavy beam from West Takone? September 13, 2011

Things went quiet on the radar anomaly front for the next couple of weeks.  The consistent run of large earthquakes around the world also halted during this period, with only one magnitude 6 or higher earthquake registered in twelve days.  Also during that time frame, a massive solar flare registered a stunning 8 on the Kp Index (which stops at 9).

Then an interesting sequence of spectrum lines occurred 29 September, and included a radar anomaly from Moree we had not seen before.  The sequence was as follows (all in Eastern Standard Time):


Purple spike at Moree:


Halls Creek


Moree comes up with a new anomaly, Sept 29, 2011

August 2011

A quiet start to August.  Learmonth had this beam to offer on the 4th:

Learmonth, near Exmouth on the North West Cape - August 4 2011

Before long we started getting a lot more line activity in the north west.  Here’s what I  noted from one 12 hour loop on August 8:

Partial beams x 30
Single solid beams x 21
Double solid beams (chopsticks) x 4
Nthn coloured lines x 12 (not all from the northwest)

Several of those were simultaneous and are coming from Pt Hedland, Dampier, Halls Creek, Wyndham and Learmonth. Coincidence?

Then on August 10 2011, two spec lines from Albany – the first time I’d seen them from that radar station. They showed at 09:10 and 13:20 WST.  The same day and into the 11th, Gove radar also made a show – and it was a bit of a confused looking one as you’ll see from this loop:

See : 128km Radar Loop for Gove, 02:00 10/08/2011 to 02:00 11/08/2011 UTC

Aside from the prolific beams coming from the north west, there was also an unusual amount of what appears to be stationary rain and weather occurring – at least, that’s what the radar indicates.  The satellite/cloud  charts seemed to disagree.  Here’s how it looked on August 14 2011:

See : 512km Radar Loop for Port Headland, 23:00 13/08/2011 to 23:00 14/08/2011 UTC

July 2011

July kicks off with another of Townsville’s circular shows.

Townsville again, July 1 2011

The next day Townsville is at it again, there were five shows starting just before 1:00am  and continued intermittently until almost 9:00am.

Townsville at it again - July 2 2011

The 3rd day in July starts with this pattern in Victoria, which is visible in all frames from until 16:30 to 23:00 EST.

Interesting pattern in Victoria – July 3 2011

While that’s happening, West Takone shows a 30 minute spectrum line, and then Hobart an hour and a half later with a 20 minute spectrum line.

West Takone, Tasmania 30 minute spectrum line - July 3 2011

Another spec line from Tassie - July 3 2011

Two days later Geraldton gets back into it, also with a spectrum line.

Geraldton spec line - July 5 2011

The radar comes back online at 13:00 WST and it does this until 13:10 WST and then goes offline again:

Geraldton, WA - July 5 2011. It was still offline at 14:30...the following day.

Also around lunch time on July 5th, Melbourne experienced a 4.4 magnitude earthquake along with aftershocks, measuring 3.3 and 3.7 magnitude.  Two hours later NZ’s north island was struck by a powerful quake – GNS Science in New Zealand said the earthquake was magnitude 6.5, but the US Geological Survey measured the quake at 5.3.

A different kind of ring from Albany - July 6 2011

Halls Creek spec line and Darwin dotty circles - July 7 2011

Ceduna beam - July 8 2011

Queensland's big orange beam - July 9 2011

Then only one hour later:

Townsville going dotty - July 9 2011

After a quiet ten days, the next image was captured by a contributor to the Weatherzone forum.  Along with the following quote, he also posted a screen shot which has since been “moved or deleted” from Photobucket:

There’s four isolated supercells heading for Perth!! shocked shocked

Perth radar going nuts, dissected by a line from Esperance - July 19 2011

Here’s the screenshot I took later that night:

Why is this blank? July 19 2011

I’m glad he posted, because along with the above blank image, it proves that some things are being edited off the WZ radar.  I’ve just found there are also no images available on the Weather Chaser archives for that time frame, not for Perth, or Perth Airport.  There is a loop for Esperance, but the 13:10 to 14:20 WST frames are missing, but it does include a Kalgoorlie spectrum line near the end of the loop:

See : 512km Radar Loop for Esperance, 01:00 19/07/2011 to 13:00 19/07/2011 UTC

Note: You’ll have noticed a series of beams beginning at 16:10 in the above loop if you watched it – that’s the radar picking up the sun and following it as it sets. Esperance radar typically does this both at sunset and sunrise.

But before the sun set that day, there was a lot of action in the north of the state as well:

Katherine, Wyndham, Dampier and Darwin join in - July 19 2011

It’s a busy shot this one.  Clearly Katherine is doing its thing, with a solid orange line in the centre of it.  Running through it is a strong beam from Wyndham. Down the coast further Dampier was beaming on and off for several hours. Check it out on the loop, even Darwin Airport gets a decent flash in.  Oh, and don’t miss the two spec lines from Wyndham:

See : 512km Radar Loop for Wyndham, 01:00 19/07/2011 to 13:00 19/07/2011 UTC

Geraldton - July 22 2011

How it looks on the loop:

See : 512km Radar Loop for Geraldton, 21:00 21/07/2011 to 07:00 22/07/2011 UTC

In this next loop, from July 23 2011, you’ll see some impressive beams crossing each other from Wyndham and Katherine/Tindal, along with a spec line (bottom left of screen, 5th frame) from Halls Creek and another one near the end of the loop from Wyndham. And Darwin still doing its dotty circle thing.

See : 512km Radar Loop for Darwin Airport, 20:00 22/07/2011 to 09:00 23/07/2011 UTC

The following day, Wyndham is still beaming:

Another Wyndham beam - July 24 2011

Here it is on the loop, along with several spec lines, also from Wyndham:

See : 512km Radar Loop for Darwin Airport, 12:00 23/07/2011 to 11:00 24/07/2011 UTC

The following day, July 25 2011, there seems to be some intensity at the Geraldton radar – only it isn’t weather:

Where did that come from? July 25 2011

Not only that, it seems to cut through the weather on the western side of it – the straight edge from the Geraldton anomaly lines up perfectly with weather near Three Springs

Geraldton radar slicing through the incoming weather - July 25 2011

Meanwhile, both prior to and after that, Albany was also doing odd things:

A persistent line from Albany - July 25 2011

This is from a post I made on Weatherzone to sum up the final week or so of July:

Things have been busy as usual in the northwest. Those Darwin circles are pretty much constantly occurring, and are at times intense with plenty of colours in them. The coloured lines pointing directly north as is visible at Katherine in the following image have also been popping up regularly on a handful of radars.
The beams from the Dampier area have backed off a lot compared to the past several months, but still happen occasionally. Also, check out Tennant Creek on the following image – it seems to have been raining in that one area there for several days now, although observations and satellite images suggest otherwise.

Busy in the northwest - July 26 2011

The following loop will give you a clearer idea of what I mean about the Darwin action, and it has a bonus beam thrown in from Wyndham:

See : 512km Radar Loop for Darwin Airport, 23:00 25/07/2011 to 12:00 26/07/2011 UTC

Geraldton spent days beaming a broken line to the west as well:

Note: the green lines are always at the same level just south of west on the Geraldton images. I can’t discern any patterns in the timing for it to be a simple glitch with each pass over that area – sometimes they’re there, and sometimes not as I’ve shown from just one day in the following image.

Geraldton western lines - July 26 2011

Albany does something a bit different on July 28 2011:

New directions from Albany - July 28 2011

Tennant Creek weirdness:

See : 256km Radar Loop for Tennant Creek, 09:00 30/07/2011 to 03:00 31/07/2011 UTC

Gove radar finishes up July with a strange little dummy spit:

June 2011

Ceduna radar delivered a beam towards the west on June 14 2011 for ten hours.  You can watch the loop here.

See : 512km Radar Loop for Ceduna, 10:00 14/06/2011 to 03:00 15/06/2011 UTC

June 16 2011 - Broome fires up for half hour from 16:50 to 17:20 WST

A busy period for the northwest of WA with "pencil lines" - this shot taken on June 20 2011


Weipa shooting an impressive double beam - June 20 2011


There's that "SKA logo" again, right in the middle of a vicious overnight storm in Victoria - June 21 2011

From Newcastle - June 22 2011


Early morning in Townsville - June 25 2011

The following show from Esperance lasted a total of 12 hours 50 minutes.  It seemed to sort itself out early on when the flash disappeared for just over an hour, but it came back.

Amazing Esperance - on for almost 13 hours on June 28 2011

Then the next morning:

Spectrum line from West Takone in Tasmania and an unusual dashed beam from Melbourne - June 29 2011

At the same time the beam stops from Melbourne, a new spectrum line starts up in Hobart for a ten minute show.  Synchronised glitches?  I doubt it.

Hobart taking over where Melbourne left off - June 29 2010

But wait, there’s more – Geraldton gave an impressive 20 minute show, along with  another “glitch” from Esperance: look closely, you will see a purple beam.  The time on the following screen shot converts to 11:00 EST :

Geraldton fires up and stays there for 20 minutes. Note the purple line from Esperance. June 29 2011

The Geraldton radar then went offline for at least five and half hours.
