After many phone calls to both Energex, and Channel 7 (both of who said each other controlled the live feed!), I was finally able to get a contact to write a formal request through. Unfortunately, it can't be done. Energex is bounded by contract, to GPATS to: a) To have a 15min delay in data (this was OK, and most people know about it.) b) To only give out data every 15 minutes c) To only show SE QLD, and no longer have all of QLD as they did last year. When I come back from the end of year chase in December, I'll commence negotiations with GPATS to persuade them otherwise. I don't like the probability though, given that I know one QLD member actually phoned and asked how much the data costs, and got laughed at and said "you'd never be able to afford it" (!) Will keep people posted if I make any ground. -- Anthony Cornelius Queensland Coordinator of the Australian Severe Weather Association (ASWA) (07) 3390 4812 14 Kinsella St Belmont, Brisbane QLD, 4153 Please report severe thunderstorms on our Queensland severe thunderstorm reporting line on (07) 3390 4218 or by going to our homepage at http://www.severeweather.asn.au +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ To unsubscribe from aussie-weather send e-mail to:majordomo at world.std.com with "unsubscribe aussie-weather your_email_address" in the body of your message. -----------------------jacob at iinet.net.au------------------------------ 002 Date: Thu, 11 Nov 1999 23:16:31 +1000 From: Anthony Cornelius [cyclone at flatrate.net.au] X-Mailer: Mozilla 4.6 [en] (Win98; I) X-Accept-Language: en To: Australian Weather Mailing List [aussie-weather at world.std.com] Subject: aus-wx: Who Turned off the Heat? Sender: aussie-weather-approval at world.std.com Reply-To: aussie-weather at world.std.com Hi all, Very interesting layer of cold air above SE QLD/NE NSW at the moment, and certainly quite surprising. AVN is going for a whopping -20C at 500mb tomorrow, this is even colder then what we average in winter! In fact, I can't remember Brisbane itself getting to -20C at 500mb all winter, the only time this happened was on May 1 of this year, of which we had a few cold-air supercells, and one spawned a tornado (coldie or supercellular?) near Gondoowindi (3.5-4hrs WSW of Brisbane) - plenty of hail too! To give you an idea on how cold this air is, compared to what would normally happen, I've calculated some CAPE's for differing day situatios that we normally get in November (all with a pressure of 1008hPa) A typical sunny November Day (Temp/DP)is 28/19, CAPE = 3496 A warm November T'storm Day - 31/22, CAPE = 5292 A Good November T'storm Day - 34/24, CAPE = 7049 Not the best way to measure the differences I know, but it gives you an idea on what we would get if the surface was "average" anyway. None the less, it appears that winter is having one last blast for the eastern states, with this high positioned quite far up north. Last night, us poor Brisbanites froze, with the mercury dipping to 13C (Brisbanites tend to freeze at much higher temperatures for those US people scratching their heads! :) Certainly a doonah light last night, and will probably be another one tonight too. Models do have heat lows/troughs taking over again next week, which is good to see. -- Anthony Cornelius Queensland Coordinator of the Australian Severe Weather Association (ASWA) (07) 3390 4812 14 Kinsella St Belmont, Brisbane QLD, 4153 Please report severe thunderstorms on our Queensland severe thunderstorm reporting line on (07) 3390 4218 or by going to our homepage at http://www.severeweather.asn.au +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ To unsubscribe from aussie-weather send e-mail to:majordomo at world.std.com with "unsubscribe aussie-weather your_email_address" in the body of your message. -----------------------jacob at iinet.net.au------------------------------ 003 Date: Thu, 11 Nov 1999 14:21:03 +0000 From: Les Crossan [les.crossan at virgin.net] Organization: Personal - ICQ 17296776 - note all times in GMT X-Mailer: Mozilla 4.7 [en] (Win98; I) X-Accept-Language: en To: aussie-weather at world.std.com Subject: Re: aus-wx: Who Turned off the Heat?

It has also been very dry. The Gulf of Mexico from which much of the central and easter US gets its moist air and precipitation has been "closed for business". That is, it has been blocked by a weak surface high pressure ridge which repeatedly develops each time it begins to break down. This has gone on now during the last month to two months. Over all, there is a large blocking 500 mb ridge anchored near the center of the US. Thus, only the northwest and northeast US get cool and wet weather. Here in the central US we have been averaging 15 to 20 degrees F above normal and we have had very little precipitation over the last three months after a very wet period last spring. The weather is beautiful but deceptively so because we are in the midst of a minor (at this time) drought. Believe me, there are no storms to chase here! Les ************************ Leslie R.

The observations on this web site have been freely available for a trial period. In the future however, the Bureau may provide this frequency of current observations (10 minute updates) only to Registered Users. Less frequently updated observations are expected to remain freely available. What the hell is this about. Does this mean that to get up to date observations from around Perth I will now need to become a registered user with the enevitable cost of doing so?????? What is becoming of the Bom. Anyone else from around Australia about to lose the most up to date and accurate real time observations from their city too? >From an upset West Australian. -- Michael Fewings Photographer of: Strike One Lightning Photos http://strikeone.com.au Web Master of: Australian Severe Weather Association Inc. http://www.severeweather.asn.au +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ To unsubscribe from aussie-weather send e-mail to:majordomo at world.std.com with "unsubscribe aussie-weather your_email_address" in the body of your message. -----------------------jacob at iinet.net.au------------------------------ 009 Date: Thu, 11 Nov 1999 13:36:09 -0500 From: "Leslie R.

This sounds like the media is continually "diminishing" the storms that Australia has. I wonder why this is? The US does have the reputation of the worst weather in the world and extremes but that does not mean that the atmosphere is incapable of producing comparable storms wherever supporting conditions develop. Obviously the frequency varies but not necessarily the size and intensity. Australia can and has had storms comparable to the US plains giants as well as our "mini" or "micro" storms. Although, as I am sure you all are aware, we have great variability in storm size here. I keep being amazed at just how small some supercells can get! I have seen them down to perhaps 5 km across and 4 to 5 km in height. These will occur in a variety of situations such as with hurricanes and tropical storms, as well as in the plains or all areas of the US. They will produce tornadoes (sometimes but rarely these tornadoes can be rather large and violent [F4]). Hail with these extremely small storms (when outside tropical disturbances) will be rare but does occur. Similarly, lightning is very limited or nonexistent. Apparently the size is controlled by the depth of the shear and CAPE as well as where in the sounding they occur. The heights of equilibrium levels will also be a limiting factor. I am tempted to call some of them 'toy' storms. However, they are typically referred to, as mentioned earlier, as mini or even micro supercells here in the US. Les ************************ Leslie R.

I have two ways, when I'm in a hurry I'll plot the air parcel plot line over a skew-t and give an estimate of CAPE (given that CAPE is essentially just a measure of the area between the air parcel plot line, and temperature line). From experience, I've been able to relate approximate size areas, to approximate CAPE's with about a 10% error. The next way, is to input the temps/DP's for differing levels in the atmosphere (into a little CAPE proggy a friend in the US made for me) you should really use as many levels as possible, but it takes far too long to input this all manually, so I normally use the sfc, 1000mb, 925mb, 850mb, 700mb, 500mb 400mb, 300mb, 250mb, 200mb, 150mb and 100mb. These are also the levels that AVN forecasts for us. By doing this...it then calculates CAPE and CIN. I'm wondering if he'll also be able to plot the actual new skew-t and do LI's etc...but I think this really gets down to some heavy duty programming! > Ours is 30.77 in / 1042mb(1042hPa if you want) temp/dp 10/6 > > and you think 28 degrees is cold.... 28C is comfortable, 24C and below for a max is cold. -- Anthony Cornelius Queensland Coordinator of the Australian Severe Weather Association (ASWA) (07) 3390 4812 14 Kinsella St Belmont, Brisbane QLD, 4153 Please report severe thunderstorms on our Queensland severe thunderstorm reporting line on (07) 3390 4218 or by going to our homepage at http://www.severeweather.asn.au +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ To unsubscribe from aussie-weather send e-mail to:majordomo at world.std.com with "unsubscribe aussie-weather your_email_address" in the body of your message. -----------------------jacob at iinet.net.au------------------------------ 018 From: Blair Trewin [blair at met.Unimelb.EDU.AU] Subject: Re: aus-wx: Bom registered services To: aussie-weather at world.std.com Date: Fri, 12 Nov 1999 10:40:42 +1100 (EST) X-Mailer: ELM [version 2.4 PL23] Sender: aussie-weather-approval at world.std.com Reply-To: aussie-weather at world.std.com > > Astroman > You're dreaming!!

I understand that the Bureau is soon issuing a defined 'Basic Product Set' which will be freely available. I don't know a lot about the specifics of what will and won't be available in this (although I believe at least some radar is likely to be in it), but suspect that it means that the level of available observations will become more consistent nationally, but that some regions will lose some services (for example - and I'm speaking purely hypothetically here, as I don't know if this is the plan - instead of having 10-minute data available around a few of the cities, we might have hourly data for all Australian AWS sites). To some extent, what's available now is a legacy of the old gopher site - those regions that had a lot of current observations available on the gopher (e.g. SA) also have a fair bit on the web, those that had little or nothing (e.g. Queensland and NT) still don't have much. If reasonably frequent current observations are not freely available, I wonder whether ASWA would be able to negotiate a similar arrangement to that used for radar?

GPATS is very aggressive in protecting its position - for example, although the Bureau has access to the GPATS data, it is not allowed to give specific lightning locations in its warnings (I am not making this up...). It's one of the hazards of having a type of data that is highly commercially valuable to a small number of easily identifiable clients (the power companies) - fortunately most meteorological data isn't like that. My understanding is that the lightning network is fairly cheap to run and that the charges are so high because GPATS has a monopoly and will charge whatever the market will bear. Unfortunately, the fact that a commercial provider is already established means that there is no way that the Government will ever allow the Bureau to establish a non-commercial lightning detection network (and if they tried the ACCC would jump on them very quickly indeed).

Actually, there are 2 lightning suppliers and they compete very aggressively. The other one being LPATS. Yes, the price is high but not because there is a monopoly but because the number of paying clients is small. The network is fairly expensive to run when factored over a small client base. IN addition, the capital investment is high because the sensors (apparently) cost around $200,000 each to install and bring online. The bulk of the data fees is used to recoup capital. You are right in suggesting the data would be cheaper if it had value to a broader base - ain't this always the case!! We have tried to broker deals between media companies and LPATS/GPATS in the past and found that even the largest TV networks can't justify the rates that the lightning suppliers need to charge to keep price parity with their core customers. The time delay on the data is the only way that this data can be made widely available without affecting the existing contracts.

I believe ASWA was setup for such a purpose. At least to gain what I call "Community Of Interest" access to registered BoM services that would otherwise cost an individual a fortune. That said, as ASWA Treasurer, it is within our current budget to fund access to more BoM registered services. In principle, I am opposed to "bending" as such to the whim of the politicians who consider that we should both pay our taxes and also pay for services that have been, in principle, already paid for by "the taxpayers of Australia". Maybe there's a "Freedom of Information" issue here...Any lawyers in ASWA or on the list care to comment? Where there's a will, there's a way... Now we ought to open for discussion among ASWA members what additional BoM services are needed. Obs and model output come to mind and after recent NPMOC performance woes, perhaps hi-res satpic imagery as well if an alternative $free hi-res site is not available. Given all of this, there is a "minor" 3rd-party distribution issue left to address but that is a mandatory step anyway. I'm willing to go to Melbourne and Canberra to hammer this issue out with the BoM and/or Government bureaucrats if neccessary. I'd like a team consisting of Jimmy, MichaelB, DonW and LaurierW if the need arose. On the subject of station obs in particular, I have been putting some thought and an archive trial toward the archive of both; http://www.bom.gov.au/cgi-bin/silo/retriver.cgi?state=nat&period=daily&data_type=clim&format_type=data and http://www.bom.gov.au/cgi-bin/silo/retriver.cgi?state=nat&period=daily&data_type=totals&format_type=data I've knocked together a little script that fetches the past days national obs files and for selected stations, combines the result into a historical "station obs" on demand. This is pretty neat because it means that provided the source files are kept (about 0.5MB per day) or indeed, the pertinent data from one file combined with the other (0.35MB per day), a daily historical obs report can be constructed for any station in Australia.

All: Interestingly enough, this fall here in the US is very warm, much above normal over much of the nation except for the northeast US and the northwest US. It has also been very dry. The Gulf of Mexico from which much of the central and easter US gets its moist air and precipitation has been "closed for business". That is, it has been blocked by a weak surface high pressure ridge which repeatedly develops each time it begins to break down. This has gone on now during the last month to two months. Over all, there is a large blocking 500 mb ridge anchored near the center of the US. Thus, only the northwest and northeast US get cool and wet weather. Here in the central US we have been averaging 15 to 20 degrees F above normal and we have had very little precipitation over the last three months after a very wet period last spring.

This got me wondering how such devices worked?? I assume that it works by measuring the RF pulse given off by the strike. You could measure the amplitude of the pulse but that would only be of use to you if: (a) all lightning strikes give off pulses at the same amplitude, and (b) the amplitude of these pulses is attenuated at a constant rate with distance, regardless of the atmospheric conditions. Both of these assumptions sound highly dodgey so I have concluded that measuring the amplitude of the pulse alone cannot give you the distance to the strike. The second idea I had is that the device might work in an analogous method to earthquake detection, which relies on two different sets of waves travelling at different velocities, so that the difference in arrival times of the two sets of waves is proportional to the distance of the observer to the source. However, EM waves travel at the speed of light which is supposed to be a constant (in a vacuum, at least). I'm not familiar enough with EM physics to know if different wavelengths travel at different velocities through the atmosphere but if they did, I would imagine that the difference in velocity would be very slight indeed and that the device would need to have a very fast clock to measure the difference in arrival times. Anyway, that is as far as my musings have got me. I'm sure there are people on this list who know more on the subject than I do so... am I missing something obvious or are these devices fairly sophisticated?? Do the lightning detection networks use a similar method or do they use very precise directional antennae and triangulation to find the position of the strike? Cheers, Pete. +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ To unsubscribe from aussie-weather send e-mail to:majordomo at world.std.com with "unsubscribe aussie-weather your_email_address" in the body of your message. -----------------------jacob at iinet.net.au------------------------------ 028 From: Blair Trewin [blair at met.Unimelb.EDU.AU] Subject: Re: aus-wx: Who Turned off the Heat?

High 20s C/80s F have occurred as far north as Minnesota (where mean maxima at this time of year would be around 5 C), and 31 C at Pierre, South Dakota. (Speaking of American temperatures, I've noticed that the maxima reported in Australian newspapers for Chicago and Los Angeles are substantially lower this year than what the American web sites show. I'm guessing that this is because the internationally-reported obs from those centres are coming from, respectively, somewhere near Lake Michigan and LA International Airport (which is very close to the coast), rather than further inland. It was a notably cool summer in coastal California - to the extent that October was, by some margin, LS's warmest month of the year - but not that cool!) Starting to get fairly cold in eastern Europe, though - -14 at Moscow two days ago.

All the reports I've seen on the subject have said that the yacht was 100 nautical miles north-east of Aden. If this position was correct, then pirates would be the least of the yacht's problems - being 50 kilometres inland and 1600 metres above sea level would be a somewhat more pressing difficulty.

I assume that issuing the data on a 15-minute delay makes it useless for their commercial customers (otherwise, it wouldn't be available on the Energex site).

Well today was quite interesting.. the storms appeared to be 'cold air Cb' storms to me at first.. the anvils were glatiated, and the cloudtops were dismal (not that all cold air Cb's are like that - that's just how they were today).. just after lunch a cell began to approach me from the SW (the cell that effected you i think).. the cloudtops were deadset dismal on this thing as well, and the anvil was glatiated.. not really looking like something you want to chase.. but as it approached the rain curtain was VERY dark.. i had nothing better to do so i decided to drive out to my vantage point and have a look.. and WOW!! Not long after i got to my vantage point this thing really intensified.. i don't know what it looked like from behind at that stage (James chambers was saying it looked terrible from behind when i left), but it has some GREAT features on the front end.. a great raincurtain, with a really really nice shelf cloud.. and a line of rain free bases ending from the northern side of the storm as far as the eye could see! When i first got to my vantage spot i could hear no thunder or see no lightning.. within 5 mins there was continuous rolling thunder and Cg's every min or so, some of which were quite intense.. well to make a long story short, i chased this storm and a line of activity for close to 2 hours! I certainly got MUCH more than i was expecting! I ended up NNE of Caboulture after staying ahead of the storm for about 45 mins, snapping pics here and there of the storm features, and FANTASTIC rain free updraft bases to its NW.. I took at least 15-18 pictures, some of which are really really high quality pictuers.. some of these rain free bases were just breathtaking.. so turbulent!! And there was so much green in some of them! The whole sky around me just looked like it was going to >>>>EXPLODE<<<< any minute.. you wouldn't pick it though! Radar was OK, but these storms were so low topped you could barely see them on the sat pics! And when i eventually let the storms go over the top of me they looked like crud from behind again.. it was quite odd.. although i think they really fizzed after they passed over me.. I also saw some very nice lightning.. with several close Cg's ( < 100m - 1 second or less thunder) and some fork lightning striking outside the storm at 45 degrees! I have some radar of the storms i am talking about - not spectacular in any way, but here it is anyway.. interesting that the storm never reached red on radar in the local loop, but in the broad loop it remained red on radar for 40 mins straight NW of Brisbane (at the time i was chasing it - it looked like it would have been red on radar).. You can see some mostly very light precip from the rain free bases (they appeared rain free to me.. but had very very light precip obviously)..
