Parts of the video I've linked are very relevant to this.
Bit of a different case with the US @Gleno71

Compared with Australia, they have a higher proportion of land through the interior (e.g. the Plains States) where enough moisture regularly penetrates to make it relatively hospitable and fertile for people to live.
Sure, a reasonable chunk of that's taken up by farming, and there are still areas like the desert southwest region which are arid.... but if you've ever flown across the heartland from coast to coast, you'll notice how the population's fairly spread out with lots of farmland or even big areas of undeveloped land once you get away from the bigger cities. That's despite the total population being far higher than Australia's.

In contrast, most of Australia's population is restricted to near the E, SE, and SW coast and adjacent inland because a large proportion of the rest of the country is so arid and difficult to sustain a high population.
Thanks Ken ,you would think though Aus population would have to eventually spread out further west as the years roll on ? Sydney itself is running out of room , though there is still a lot of land in the Far NW metro area of Sydney though thats slowly Filling up.

How large of a population could Brisbane handle? Will Brisbane eventually be house upon house from the coast to the Toowoomba range ?

RWM - Have you got a photo of the location in the 60s? I have fond memories of Brisbane from then on overnight mail train trips (steam of course) in May & August school holidays. City Hall was tallest structure around.

Another picture of Brisbane from the Bygone Brisbane site. What is significant here is this photo, taken in 1877, is from the exact site where the Brisbane Regional Office or " Dracula's Castle " was later built, when, I don't know. I worked there from 1963 till my Observers Course

From an academic perspective I did researched in sustainable urban management as part of my Masters degree I found that population growth for SEQ would be doubled by 2050 but unfortunately we require another Wivenhoe sized dam to support it. So no we will not able to manage the growth like we seen in Sydney and Melbourne in past 15 years.

If you stated a housing urban area from the coast to Toowoomba that will be a size of LA Basin with population of 18million. So its impossible.

A number of flights inbound to Brisbane have been forced to hold this morning due to the ongoing fog. QF751 (a 737-800 from Townsville to Brisbane) just said that that they're going to attempt autoland.

As at 8:30am, overall visibility there is still down to 600m, down to 350m in some directions.

Multiversity - Here is 50's photo of the old BoM building ....Its the smaller building with the tower on top to the right of the larger one with the Arnotts sign on top ( Old Trades Hall building ). That 1877 photo I sent out earlier would have been taken at its base.

Some of you may have already heard but Brisbane's average max temp for last month of 19.9C ended up being the lowest on record for July at the current CBD site whose previous record was 20.6C set in 2008.

But not a record breaker for the previous CBD site whose lowest was 18.7C set in both 1901 and 1938.

There's been a lot said about last month's average max temp also being the coldest since 1984 but it's impossible to know for sure since there was a gap in the obs data for about half a decade in the 90s when there was no "pure" CBD site.

Most of the ingredients for fog look to be present in many sheltered portions of Eastern QLD over the next few mornings…. although not every single place will get fog every morning.
EC fog (yellow pixels) for 7am tomorrow and Thursday above.

Also still looks on track to become very warm by the end of the week with temps a number of degrees above the average for early August although this does partly depend on a cloudband not coming across too early and limiting daytime temps.
Then cooler W to SW winds come in and drop the temps noticeably over the subsequent several days after that. Frosts should also creep eastwards again after the temps drop.

Yep those three images were taken at 4:45am, 4:55am, and 5am. I didn't even know that was a new casino they're building until you mentioned it and someone else on facebook.
I think its a mix of apartments and a Casino. The only reason I know about it is clients always ask to show it the background in proximity shots.

Q: Is this a subsidence inversion?
Q: What height does landbreeze usually extend to & does it's component show up in wind direction?
Hear it but can't see it. Cloud base below 7000' prob 5000' from BOM aero dia & Windy.com.
737 is a Max 8. Has had a life with Lion Air. Presuming all 'bugs' ironed out & pilots are all trained & confident.
Batik Airlines - new airline for me.

Coarse sea spray inhibits lightning​

Lightning is the anger of the gods, and a good dose of salt will calm them​

Lightning doesn’t have a taste for salt.​

Some newly published research showing that rainwater worldwide is no longer considered safe to drink.

Including Antarctica and the Tibetan Plateau

Quite a scary thought at the pollution and long lasting damage we have done to our planet

ABC headline today
when I read about these climate drivers I think what sort of synoptic setup is going to to help the IOD etc deliver the goods. In the end the highs,lows,trough, surface and upper over and around Aus, have to all combine to make it happen.

Q: Is this a subsidence inversion?

Hear it but can't see it. Cloud base below 7000' prob 5000' from BOM aero dia & Windy.com.

A: It's actually hard to tell at what height/s that cloud is in the photo because it could either be stratocumulus or altocumulus, or both. The sounding showed some shallow layers of moisture a few thousand feet up under a small inversion (which may have caused some stratocumulus) as well as some moisture in the midlevels (which may have caused some altocumulus). This is also consistent with the METARs from Brisbane Airport earlier this morning which were reporting a mix of low (ranging from 2500 to 4500ft) and middle level cloud (20,000 to 25,000ft).
I saw both Sc and Ac in the sky earlier this morning as well.
There's been a weak ridge lying back over us although no strong midlevel high or ridging above.
ICON's cross section of vertical motions over Brisbane for 7am today above shows some midlevel subsidence over us with some weak upmotion above that.

A: The landbreeze is usually fairly shallow here. And yes, landbreezes often show up clearly in model wind fields as a local light southwesterly flow that pushes out from land during the overnight/early morning hours.

Above - Series of extreme forecast index plots using the EC ensemble for later this week showing how widespread that warmth will be over the eastern states and northern Oz.
Scale goes from -1 to +1 and is based on what's typical for this time of the month in the year. Some places could come within record-challenging territory although it often takes a fair bit to break monthly records so early in the month.
For example, Julia Creek in the NW inland of QLD's currently forecast to reach a max of 36C by Friday which is getting close to its August record.

Also the sheer scale of that massive area of low pressure over the waters south of the continent. The size of the area of damaging strength wind gusts is similar to the size of the entire Australian continent. Both images from earlier this morning.
