Re: Vic - heralding in March with humidity and an Easterly d

Post by Harley34 »

See ya Summer! 14 degrees here now with the passage of the tail end of that cold front. Experienced 50-60 km/h gusts with around 3-5 mm of rain.

Pretty cold for March, but that is evident due to those Strong High's now moving North, allowing these fronts from the Southern Ocean to brush Victoria and slam Southern Tasmania.

Another month, and we may see some ripper fronts pushing through with squall lines and high winds, etc. Transitional stages are always fun, and i reckon in around 8 - 10 weeks time, Winter will be on our doorstep.

Just looked at that monthly rainfall/temperature climate outlook that the BOM posted, got to admit i disagree, and as this is only computer modelling based on averages, i would be surprised if i turn out incorrect. One of those models said lower rainfall for VIC for Summer, and we ended up with record - breaking rainfall..

Feb: normal average 25.4c, Feb 2011: 24.9c (anomaly -0.5c)

Only town/city (apart from the Melbourne CBD heat island) thats had a slighty warmer than normal Summer in regards to daytime temps as December cancels itself out cos it has a 0c anomaly while January's anomaly is slightly bigger than Februarys therefore it has been ever so slightly warmer than normal in Bairnsdale interms of daytime temps this Summer.

Wangaratta aerodrome
Dec: Normal average 29.0c, Dec 2010: 26.6c (anomaly -2.4c)

Feb Normal average 30.9c, Feb 2011 28.2c (anomaly -2.7c)

Alot cooler than normal daytime temps this Summer in Wangaratta

To sum up I would like to say that I am aware that nightime temps this Summer across the state were above average but the daytime temps were below average more than BOM lead us to believe and telling us that "Melbourne" had warmer than normal daytime temps is very misleading and very misinformative. As you can see alot of the state and Melbourne area had below average daytime temps, it was also alot duller than normal with less sunshine that combined with high rainfall and lower temps during the day as made a few people complain about the cooler Summer as it has been nothing compare to recent Years.

Thanks Johnno for the statistics. It helps a lot more when people will show a large number of statistics to support their statements.

For us we had 2mm to finish off the month. For Feb we had a total of 240.5mm. YTD: 333.5mm. Since the start of dec we have had 493mm

Interesting debate, I will copy and post more of John's post into Climate for further discussion there.

Humidity and easterly dip that it appeared on our charts weeks ago has been replaced with feral SW winds and heavy showers, 5mm here from them this morning with a little bit of hail earlier on.

Much drier sunny skies out there now with a squally SW wind.

I think we can all at least agree that it's been a summer lacking in extreme heat. Just 5 days over 30 C here all summer - one in December, two in January and two in February.

The satellite pic is showing lots of what looks like higher level stratus type cloud trailing behind the cold front that has passed. I wonder if this high will have some reasonable upper cloud cover associated with it?

Also the low to the south east of the high in the main jetstream,is very intense as seen on the BOM jetstream thickness map, its center is 940mm.
That strong low in the main polar jetstream appears to be blocking that high somewhat causing some tighter isobars on the eastern flank of the high,that could result in continuing high winds from the SW and maybe a little chilly.
just a thought.

We got a cold wintery gusty NW->SW change through here late morning delivering another welcome 2mm to put us circa 16mm over past few days. We will now stay green till next summer I reckon - which means Lake Glenmaggie (at 90%) wont be able to buffer much of any potential decent rain event Gipply gets (we havent had one this La Nina yet). A cool day with a late arvo max of 21C (19C now).



I'm not able to get into the climate thread here (so use WZ instead), but am quite alarmed at Johnno's post (thanks for a big effort there Johnno) compared to the stat's BOM have put out (thanks RG) and have some questions on this:

1. What does the BOM define as "average summer temperature" - I looked at the BOM glossary to no avail, the normal lay person would naturally interperet this to be the average of all daily maximums imo - (hence easy meat for mis-interpretation and I hope NOT - mis-representation).
2. Why does the BOM use 1960 - 1990 as the database for "average"? We all know we have been warming through the 20th century (glaciers are shrinking not growing), so why dont we we use ALL Melbournes historic temperature records, through to yesterday (now), to establish what is known as "average" (whatever the formala for average is given that Johno, me, and many of us obviously have "no idea").

Is the BOM aligned politically with the GW mantra?

Day time temperatures across Victoria were below average and night time temperatures above average. The average is 1961-1990 - a period which had seen about 0.5 of global warming, but doesn't include the near 0.5C which has happen since the mid point of the 1961-1990 normal period. Any number for Melbourne is that for 86071 - the central city site. You can get your averages and anomalies at http://www.bom.gov.au/climate/current/s ... mary.shtml" onclick="window.open(this.href);return false; .

The Vic average mean temperature for summer should fall between +0.1 and +0.2C - final numbers will appear at http://www.bom.gov.au/cgi-bin/climate/c ... 2&ave_yr=0" onclick="window.open(this.href);return false; this arvo.It will be our coolest summer since 04/05.

Humans are not good at recognising the temperature anomaly in a place like Vic, and particularly so with a summer like that just passed which had record rainfall, high humidity and many very cloudy days.

Cold and showery up here today - got very close to hail with a couple of the coldies - but the best is passing to our south through Tassie.
We are cold, and getting colder globally, in areas where we are supposed to be warm in La Ninas. Standby for the next stage.

Relying on night time temps with 2 million more people since 1961 is an even bigger joke, which im sure you already know, but conveniently leave out.

For the record, the 1930s decade was the warmest in the last century by a long way, ask the PDO, it tells all.

Excellent analysis and assessment.

The BoM are being disingenuous if not deliberately deceitful with their "warmer summer" tripe. Leaving aside the fact that daytime temps were all below normal on average, given the strength of the La Nina and the amount of rain Vic has had of course night temps would be warmer than usual (more cloud, less irradiation et al)! Any derr brain would recognise that, and those that try and sell it as AGW are deceitful, lazy and corrupt - morally and ethically.

I will re-post these questions here, as I have in WZ - simply because I want to understand the answers:

1. What does the BOM define as "average summer temperature" - I looked at the BOM glossary to no avail, the normal lay person would naturally interperet this to be the average of all daily maximums imo - (hence easy meat for mis-interpretation and I hope NOT - mis-representation).
2. Why does the BOM use 1960 - 1990 as the database for "average"? We all know we have been warming through the 20th century (glaciers are shrinking not growing), so why dont we we use ALL Melbournes historic temperature records, through to yesterday (now), to establish what is known as "average" (whatever the formala for average is?)

From the above post, does that infer that the BOM is using night-time MINS as the summer average??? - (surely not). That can only leave that the BOM uses the mid point between the nightime min and the daytime max as the daily figures to finally become the "average Summer temperature".

A response on WZ stated that in his research, the 1960 - 1990 period currently used by the BOM has been chosen since it is a "convienient COOL period" and if they went back further in the 1900's two other previous occasions of hot summer periods would have pushed the "historic" data far higher which would have made this Summers average (and I STILL dont know what makes up the figure!! - despite trying to all a reasonable layman can do) LOWER than average.

Are we being snowed???? Dont we deserve to be delivered data from our Government institutions that passes a certain standard so that people can make their own descisions based on REAL data!!? I have read that the BOM have had reservations over the "old methods". I am also aware that old data it often corrected (which I agree with), BUT WHAT ABOUT THE DATA FROM 1990 - 2010 - which the best instruments the world has seen. You gotta ask the question dont you!? (no matter which camp you are on).

And this rant is based on my/(OUR??) knowing that we had a cooler summer than usual - because we were there! The poor ghosts above cannot tap on the BOM's door and say "but it was far hotter in many 1900 - 1959 summers than those of 1960 - 1990 ).

Aren't we breaking records worldwide for both hot and cold and every aspect of weather.?
Tornadoes, severe storms, heat waves, cold waves, intense rainfall, cyclones,blizzards,droughts,size of hail...intensity of snow fall, cloud cover, no cloud cover
oscillation index record, dare l say sea temps hotter but as anyone found some getting colder temps
We seem to be having extremes.
Any global data available on extremes and records broken.
Is there a good site where someone is keeping track.
We have broken records in every season.
Two years ago summer was early in November,with a heat wave of 40's and a long extended summer
This year is looking to be early winter?

Crikey, what do you personally think of this last VICTORIAN summer? - was it hotter than average or not?

No more rain here, a cool day with SW'ly abating, 10.4 - 23.6C, baro back up to 1014 hPa.

How do you define average petros? Then l will answer
Found this for you re: definition of average
from southeastern australian climate initiative
They define average according to BOM, I couldn't cut and paste extracts because is a PDF file
its on page two
and according to their definition of average it was chosen as a time period that was very very wet period in our Australian history 1961 -1990 (baseline average)so if we were above their definition of average then.... this summer.. we were
very very very very wet . :roffl:

Just checking up on extreme temps in Victoria or Australia or what l can find. Here's one to start
Reference:

AUSTRALIA

HIGHEST RECORDED TEMPERATURE:

* Oodnadatta, South Australia 50.7 C (123.3 F) on the 2nd January, 1960


LOWEST RECORDED TEMPERATURE:

* Charlotte Pass, New South Wales -23.0 C (-9.4 F) on the 29th June, 1994

Interesting to note they are both recorded in the modern era! 1960 and 1994

Interesting discussion everyone, but why are we discussing climate issues in a breaking weather thread?

It looks like this system hasn't come off as initially postulated. Perhaps this is why this thread has gone so far off topic.

Yes, this really has veered away from the topic! Shows how benign our weather is right now - I think people are going troppo. Or should that be 'Sub-troppo' ;)

I'll lock this now. Remember, if anyone wants to debate / discuss climatology, please feel free to contribute in the Climatology thread. It is password protected, so if anyone wants to get in - send a PM to Karl Lijnders or any other Admin.
