X-Authentication-Warning: neumann.maths.monash.edu.au: robert owned process doing -bs Date: Sun, 30 Jul 2000 03:58:51 +1000 (EST) From: Robert Goler X-Sender: robert at neumann.maths.monash.edu.au To: aussie-weather at world.std.com Subject: aus-wx: Re: Local effects - sea breezes Sender: aussie-weather-approval at world.std.com Reply-To: aussie-weather at world.std.com Hi all In my study of the morning glory, I have come across a few papers regarding the inland penetration of sea breezes. These look at some observations and compare them with the results from numerical models. Unfortunately, in these papers there is no Bendigo specific study, but the case of the 'Goondiwindi breeze' may be applicable, which springs up on many summer evenings. Goondiwindi is located 315km inland from the central Queensland coast, latitude ~28S, and about 120km inland from the coast there is a 600m high ridge. The eastern side is steeper while the western side tapers off. The explanation given here was developed from the numerical modelling results of this sea breeze. During the day the sea breeze moves inland but stalls against the ridge where it loses its identity. Just after midday a sea breeze like disturbance develops in the lee of the ridge. So basically, you could think of it as the sea breeze 'jumping' up the ridge, but probably due to anabatic effects. This new sea breeze in the lee continues to develop through the afternoon and propagates down the hill and reaches Goondiwindi by ~2100 local time, where its speed of propagation is around 8m/s (~30km/h). A model run without the ridge present resulted in a weaker sea breeze which arrived over an hour later at Goondiwindi. So, the presence of the hill speeds up and intensifies the sea breeze. To confirm that the air arriving at Goodiwindi indeed originated from the sea, tracer particles were put into the model, and this showed that this air did originate from the sea. A study was also done on the Canberra sea breeze. In this case, observations were carried out in the 1940s during summer by following the sea breeze by car and/or plane. The sea breeze has been recorded past Canberra (114km from east coast), to Jugiong (191km inland) and Wagga Wagga (270km). The 'idealised' topography used in the model, shows the diving range rising up steeply on the eastern side to a height of ~600m in 50km (of which Canberra is just west of the peak) and then tapering off to the west. The times of arrival of the sea breeze at Canberra seems to be around 1700->1900. The limited model output shown in this paper seems to show a similar process that that explained above. In my modelling simulations of sea breezes, I have found that an assisting geostrophic flow (in this case an easterly), increases the depth of inflow into the sea breeze. Without this aiding geostrophic flow, for my case this inflow is just over 500m in depth. [I state 'my case' as the surface heating I used, which is for Cape York Peninsula, would be slightly higher than from the Canberra region, which would result in a more intense sea breeze.] With an aiding geostrophic flow of 5m/s (18km/h), the inflow increases to a depth of about 1km. Looking at the wind profiles taken from the observations taken at Canberra shows that inflow depths did indeed range from 300m -> ~800m depending on the direction of the geostrophic flow (smaller heights for opposing geostrophic flow). If the aiding flow is above ~10m/s then this tends to have adverse effects on the sea breeze head reducing the temperature contrast and velocity change that occurs at the 'front'. In another study, the Coorong-Renmark area was looked at in January 1959 and 1961. During 1961 a line of 9 stations aligned perpendicular to the coast and reaching 165km inland were manned. Here it was found that the sea breeze moves inland at increasing speed until 2200hr (local time) where deceleration occurs and it may even reach Mildura (310km inland). In fact propagation speeds of sea breezes are found to increase in speed after sunset which is believed due to the cessation of daytime convection. The distance the sea breeze is penetrates inland is thought to be primarily governed by the Coriolis force which is dependent on the rotation rate of Earth and the latitude. So, at lower latitudes, the sea breeze can propagate larger distances. In the morning glory case, the east coast sea breeze that develops on the eastern side of Cape York Peninsula travels around 400km from the east side through to the west side. However, there is one thing to note about the penetration of sea breezes inland. This is shown in the following study on the Kalgoorlie sea breeze, and to some extent in my morning glory simulations. There are occassions where the propagating sea breeze actually generates wave like disturbances at low levels which move ahead of the sea breeze even after it has 'died'. It is possible that observations may not be able to distinguish between the two cases, ie a bona-fide sea breeze, and these wave disturbances. At the moment, I'm not going to touch on these wave disturbances as this email is bloody well long enough :-p Data on the Kalgoorlie sea breeze was obtained by the person driving his car along the Esperance-Norseman-Kalgoorlie road and following this sea breeze. He found that in summer the sea breeze not infrequently penetrated as far as Kalgoorlie, which is a distance of 350km. It typically arrived around 2210->2335 (local time). However, numerical modelling showed that when parcels of air were tracked, any sea breeze air was lost after about 250km. The disturbance that continued was thus a wave and not a strict sea breeze. > > The thought of this phenomenon being a sea breeze is one that has also > crossed my mind in the past.

Hi All
My Brothers went to Springbrook Thursday, they missed the snow falling, though it was 2C at 2pm.  My brothers recorded the news footage of it. 
 
Records of snow at Guyra
1994  April 20th
  • The lowest max for April is on the 12th at 7.5C
  • Earliest snow fall for years, some residents commenting it was the first fall of snow before Anzac Day for over 20yrs.
  • snow extended to Black Mt, Bald Blair, and Ben Lomond.
  • widespread snow 2-6cm.
1996 July
  • Biggest fall of snow since 1984
  • Devil's Pitch was closed for more than 14hrs
  • time of going to press, Moday evening ( 14th July) snow was still falling in eddies around the street lights, it remains to see if records will be broken.
1984 3rd July
  • Post Office recorded 25cm, but it was deeper in many parts of the district and drifts were reported up to 1.5metres
  • even a week later banked up snow remains
  • Council eqipment was extra busy during the week, graders cleared snow from many of the roads of the district.  Guyra itself council used front end loaders to clear away deep drifts and tonnes of snow and ice were carted away  in tip trucks to be dumped in less inconvenient places.  They ran out of places and used a gravel section of a street.
  • P.O's Kerry Gittoes - remembered how he had to make his way down to Armidale, with only the tops of the guide posts to show the way.  At that time  snow drifts had reached 6ft.

Hi All
Just got back.  There was still patches of snow around as I left Guyra at 9:00am, and also at Ben Lomond Range.  Temp 3.9C at 8:30.  Now for the Guyra story:-
 
Thursday
 fine all morning, previous day the cab drive said they had 13mm of rain
at around 2:30pm light snow (melted on the ground 3.3C)
Went down to the Library to view some snow records at approx 3:00pm, on the way down there were more snow flurries ( sticking to my Driza-Bone).  Looked at the records for 84,94,96. 
At about 4:00 ish I looked outside from the Library - saw snow falling, it was starting to cover the ground, then it stopped and the sun came out - I decided to head back to the caravan park ( highest caravan park in Australia)
At 5:00 (temp 0.8C) - I saw small ice pellets(sleet) coming down outside my van.
At 7:00(temp -1.0C) - I stepped out, and to my astonishment - there was snow everywhere, I didn't hear anything!   It was blowing snow - snow all over the cars in the undercover shelter. F&*%ing freezing winds( cut me like a knife)
Went to bed early about 9:30.
Woke up at midnight - it was blowing snow (very very cold -2.7C) , snow was deep about 4cm - about 12cm.
 
Friday -
Woke up at 5:00am, snowing lightly
At 6:00 (when it was light) - I was greeted by the sight which I had travelled to see.  The New England highway was completely white - snow was about 2/3cm on highway and about 4-12cm everywhere else, except the drains along the highway where the snow was about 20+cm.
At 7:00 temp -1.4
At 8am - 11:00am I walked the town taking photos -roads, roofs, cattle,sheep.trees etc all white.  Snow at the park at Mother of Duck lagoon was thick about 10cm - 30cm.
Main street  - footpaths, bowling green(white!) was covered.
Noon - 6:00 - started to thaw as the sun was out.  People made snowpersons(politically correct!) - one in particular was over 6ft.  It was going into the local paper.
Highway was closed Thursday, I never heard any trucks!

That's 4 inches across? Clyve, I'm going to do a more thorough study of this snow event, but my early thoughts are that most of the snowfall north of the Snowy Mountains came from two events -- snowshowers with the "front" that swept up the divide during Wednesday, and the secondary trough that moved up the coast on Thursday afternoon and evening, swinging the lower/middle atmosphere winds east of south and generating a slow-moving cloudband from which the fine-grained snow fell. There were some local falls that don't fit this pattern and have yet to be explained, but I think these were the two main broadscale events. The Wednesday event produced pretty typical snow, and I had the good fortune to be driving north along the divide more or less with (or a short distance behind) the front all the way from Orbost to Blackheath. The snow this produced was "normal" -- i.e. flakes from 5 to 10mm, tending larger when falling as wet snow with the temp around 1 to 2, and smaller as the stream cooled to 0 and below and the snow fell dry. In the Thursday event, the snow at Blackheath could almost be described as drizzle-snow, and may well have been formed by the same mechanism that produces drizzle on the Blue Mountains -- i.e. a relatively thin but well mixed moist southeasterly. It also fell in completely calm conditions, at least at ground level, with surface temps around -1, so that coalescence would have been minimised. It fell consistently and moderately for a little over an hour at my place, then intermittently and lightly for another two hours, yielding a depth of 4cm, and melted in the raingauge to yield 1.9mm, so density on the ground was much less than the normal 1:~1.3 that I'd expect here. Also of interest is that it produced snow west of Lithgow as well, rather unusual for a sou'easter where the rain cuts off sharply west of Mt Victoria. I'll be interested to go through the data, especially the uppers. I have the AMDAR data from aircraft into and out of Sydney Airport, which will give some interesting time/height temperature profiles, and perhaps explain why the cloudband seemed to stall over the area for several hours, prolonging the event over the Illawarra escarpment and into the Blue Mountains.

It would be preferred that you bring a video of no more than 15 mins per person. You will surprised just how much action you can squeeze into 15 mins. It notice that the proposed meeting structure has time allocated for each state, so we should get to see many videos. Just let me know if you intend to show video, no need to reply if you already have. This is so we can get an idea on numbers. If we have time left we can show longer tapes at the end.
