Why? I have come to believe that given the synoptic-scale ingredients for severe weather are in place, you need to know those surface boundaries as well as possible to get anywhere close to the good storms before the show is over. John wrote: > My own observations subscribe to the theory that a dry line of sorts forms > on or near the inland trough. This trough is a feature for most of the > summer.

Sounds like a thermal/heat trough to me, given it is a semi-permanent feature. How the trough relates to 'a' dryline, that might be an unresolved (pun intended) issue. I was hoping that there's someone who has looked at spring surface data for some time which *might* show some of those surface boundaries (if the station spacing is not loo large). Correlate that with satellite/radar images of storms popping to see that important connection. John part II: > I have noticed that really good storms require a nice strong NE sea-breeze, > and many storms are located at the leading edge of the seabreeze front, and > seem to move east with this front in late afternoon or early evening as the > seabreeze lessens.

I believe you refer to ``really good *observed* storms'' associated with seabreeze convergence. These types of storms are confined to the coastal regions, though. Michael adds on the subject of seabreezes > ...Illawarra where the seabreeze makes it to the escarpment by mid morning, not > only that but the escarpment provides a perfect setup for an inversion, > there is no vertical seabreeze front as such at all. Convection is usually > nil. Could this be blocking by orography? I guess that this ``blocking'' effect is most pronounced when the stratification is quite stable, or an inversion is present (overrunning by warm continental air?). and Anthony elucidates: > For a typical day of thunderstorms in SE QLD, you normally have a NE'ly > flow for at least 24hrs before the potential storms developed.

They then nearly always move ENE-NNE (inclusive) - there's > always exceptions though (hence, 'nearly always.') The consistent NE flow builds up the dewpoints; this migth take a few days after a prior frontal passage dries out the boundary layer. The $1,000,000 question is: do storms develop well inland so that their development has nothing to do with the seabreeze, or are almost all storms just riding the seabreeze front? I would expect plenty of development well inland as well come October this year. > They form in that > area because of the mountain ranges there, and though while not very > significant (ie, to my knowledge, only 2 are higher than 1000m(3000ft), > and they are on the border ranges), do play a very significant role in > thunderstorm formation.

There are discussions floating the the WWW whether ~100m hills make storms tornadic or not. But, orographic lifting/convergence/ vorticity generation is a separate issue (and is also awfully complicated). It is interesting to see that that the orography produces a 'small max.' in the thunderstorm formation, though.

I've heard they are tubular clouds that form in the vicinity of Darwin. Is that so? Are they a type of cumulus? What or where can I find out more about them? Sallie Greenwood >> Sallie, The morning glory clouds are roll clouds caused by large-amplitude waves in the atmosphere. They tend to form regularly spaced cylindrical clouds that can be hundreds of km's long. They are quite spectacular, although the winds inside them are gusty and you wouldn't want to fly a light plane into one. They can be formed by sea-breeze convergence over the Cape York Peninsula at times where a strong inversion layer exists aloft. Where the two sea breezes meet, they push the inversion layer up into a long ridge without breaking through it. The sea breezes die at night and the inversion "ridge" collapses and propagates into the Gulf of Carpentaria as a series of waves. The clouds form in the "peaks" of these waves. For more info try... Christie, D.R., 1992, "The morning glory of the Gulf of Carpentaria: a paradigm for non-linear waves in the lower atmosphere", Australian Meteorological Magazine, vol. 42, pp. 21 - 60.

Ceduna got to 36, which is an early- season record for them. 56 km/h seems to be quite a popular wind observation in SA! Dust is being reported at a few Eyre Peninsula stations, although not as many as I thought might have been the case. Tarcoola's 35 is also an early-season record. Adelaide's 28.5 (at last count) narrowly misses an early-seaosn record (29.1 on 31/8/1911). WA will be worth watching at the other extreme. Perth Airport's September record low max is a remarkably soft 12.7 (considering that October's record is 12.3). If the numbers that Jacob's quoted hold (I've seen 9.5 at last check at Perth Metro) we could well see some records falling. Any reports of snow in WA?

Sender: aussie-weather-approval at world.std.com Reply-To: aussie-weather at world.std.com Hi all, Just letting you all know that i saw two funnel clouds today and one waterspout off the coast of Perth. I was at work and could see some good cells coming in, one had a wicked anvil and i could see a lowered base at a distance, so i left work, as you would, and was heading towards it when this funnel just came down, almost to the ground it was, i took a pic as i was driving, it was very quick. I then kept going towards the storm, came up over a hill and there was this water spout down!! right infront of me!!!!! only about 2ks or less even away. I took about 2 or 3 pics, it only lasted about 3-5mins. It died as it hit the shore line. After the cell passed i saw another funnel at the rear of it from a distance and took one pic. Ill try to get em developted tomorrow sometime and will paste em asap. Thats 6 water spouts, 9 funnel clouds and 5 tornadoes here for winter, not bad at all. Im glad i got to see at least some of em. (geeze i love living in WA!!!)
