Hi all,
    Well WA is still having reports of flood damage coming in as ppl,
can get out and about, With  most farmers in the Effected Area's though
the Wheatbelt & Great Southern Area's the Worst hit. The Ground is that
wet in places that even 4WD's are out of the Question for most farmers.
Stock loses are exspected to be reasonably high in most area's as most
of the Sheep in the region have just been Shawn in the last week or so,
hence there dieing of exsposure mainly or lack of feed.
    The Swan River  is flooding at Caversham near (Midland) already, the
question is how much more will it flood, that will depend on how much
was water is to come from the catchment area of the Swan.

a few articals from the ABC web site...

                    Interstate repair teams flown-in
                    to restore WA phone services

                    Telstra repair teams from Queensland and South
                    Australia have been flown to WA to help restore
                    services to thousands of customers, cut off by the
                    weekend's unseasonal storms.

                    Four thousand faults have been reported throughout
the
                    State with Kalamunda and Roleystone the
                    worst-affected areas.

                    Flooding in the Wheatbelt is preventing repair crews

                    from gaining access to damaged cables in many
                    areas.

                    Spokesman for Telstra Richard O'Connel says it is
                    expected the number of reported faults will
increase.

                    "Across the weekend we had in excess of 200 staff
out
                    fixing faults with additional staff flying in from
                    Queensland and South Australia," he said.

                    "We've got enough [people] on the ground but it's
                    difficult to access a lot of these flood-ridden
areas, we
                    anticipate some services may not be back on until
                    Monday-week unfortunately."

Govt assessing storm damage
                    assistance

                    The Western Australian Government will decide what
                    assistance is to be given to farmers affected by the

                    weekend's unseasonal storms, when the full extent of

                    damage is known.

                    WA Farmers Federation president Kevin McMenemy
                    has described the situation as similar to last
year's
                    Moora floods, but on a much wider scale.

                    There has been significant losses of newly shorn
sheep
                    from the cold, wet conditions and some country road
                    networks have been badly damaged by floodwaters.

                    Premier Richard Court says the extent of damage
                    should become apparent in the coming days.

                    Farmers in the Lake Grace area report losing up to
700
                    sheep each as a result of the cold and wet
conditions.

                    At Lake Grace township, 135 millimetres of rain fell

                    between Friday afternoon and yesterday afternoon.

                    Agriculture Western Australia regional manager
                    Amanda Miller says although the rain has eased, cold

                    easterly winds are continuing to make conditions
                    difficult for stock.

                    Meanwhile, the only detour between Ravensthorpe and
                    Jerramungup, has been closed to light traffic.

                    Due to major flooding, only heavy vehicles and 4WDs
                    are able to take the detour through Lake Grace and
                    Lake King.

                    Authorities hope to reopen the Lake King to
                    Ravensthorpe Road to light traffic later this
morning.

                    The South Coast Highway, between the two Great
                    Southern towns remains closed, and repairs at the
                    Phillips River Bridge are expected to take at least
a
                    week to complete.

                    The wet conditions forced the closure of the
Fitzgerald
                    River national park at the weekend, but the park is
                    expected to be reopened later today.

                    The Department of Conservation and Land
                    Management says roads inside the park were closed
                    because they are more prone to damage from vehicles
                    when they are wet and because dieback tends to
                    spread more easily in the damp conditions.

All interesting stuff Blair, love all this record stuff. Maybe its from
my running days (records/statistics etc), I dunno. Any more thoughts on
the ECMWF cold outbreak predictions? How cold do you think it might get
and how far reaching 
(Cent. Tablelands?) might such an outbreak be, if ECMWF is right?

Hey all!
Last nite, while participating in a weekly trivia contest at the mean fiddler in Sydney's North west, a question was asked about relative humidity. The question was which two capital cities have the highest average annual humidity?
 I answered Darwin, and Brisbane, thinking that my weather knowledge had once again came thru with the goods, but i was surprised to see, that it is actually Sydney, and Darwin. Stagged with this wrong answer i confronted the trivia master, who promptly pulled out a BOM weather stats book and showed me my failings.
 
Talking about this on IRC with Ben Quinn, he then expanded my brain, by telling me that warmer air hold more moisture, and that Brisbane has a higher average maximum temperature than Sydney, and therefore would actually be more humid. Some of the figures Ben got from Climate of Australia book, that at 3pm Darwin has a average RH of 54%, Brisbane 53%, and Sydney 57%, and at 9am Darwin has 73%, Brisbane has 66% and Sydney has 68%(these are average annual figures).
 
So what is everyone's thoughts, should temps be brought into calculation? do these figures falsely represent the true nature of humidity? what is the true nature of humidity?, and does this sound like a promo for a Unsolved Mysteries show?
Discussion please.
=)

Sure, Sydney has the highest annaul relative humidity but Melbourne does pretty well in Winter especially mornings. But that is boosted by the fact that on a cold and foggy morning the RH is close to 100% and might stay that way for many hours - but its hardly sticky wetaher. Sure the most uncomfortable Capital city in Australia is Darwin (if we take the liberty of calling Darwin a capital) - for at least 6-7 months per year and Brisbane would follow - especoially in Summer and Autumn but as long as the term relative humidty is used - then its another achievement for Sydney.

Relative humidity is not an absolute measure of humidity. It is a measure of moisture in the air relative to the maximum amount air of that temperature can hold. To compare humidity between places you need to use a measure of absolute humidity. There are several of these, (vapour pressure, dew point etc.). Once you understand this it comes as less of a surprise to learn that Hobart actually scores the highest annual relative humidity in the country.

Comparing a more absolute measure such as dew point sees Darwin win hands down. This also more accurately reflects the body's response to humidity as well. The cooling effect of evaporation is more tied to the vapour pressure of water in the air - and much less by the relative humidity. This is because the body is a constant temperature.

Relative Humidity is just that - % of water in the air relative to the temperature of that air parcel - so realistically Temperature is already involved in that equation ( I hope thats the way I remember it :) It doesnt surprise me that Sydney is higher then Brisbane - although Sydneys mean temp would be lower, it has a more all year round rainfall and more abundant moisture supply from frontal activity etc etc then Brisbane. However qhat oftens confuses people about humidity is the comfort factor - Sydneys higher humidity is often less noticeable because of the lower temps that is assoc. with. Sydney often can have temps of early 20's with humidity of 80% or higher - esp with a nice moist SE'er - Southerly blowing - yet it can go unnoticed due to relative comfortability. Also those figures - are they year avergaes? I can tell you that humidity levels here are alot higher then those figures during the wet - eg at 9am temp was 28 with DP of 24 is about 85%. Hope this helps?

Dewpoints in the area are around 18 to 20C, and CAPE at Giles this morning was ~2000. -- Laurier Williams Australian Weather News & Links http://ausweather.simplenet.com +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ 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------------------------------ 012 From: wbc at ozemail.com.au (Laurier Williams) To: aussie-weather at world.std.com Subject: aus-wx: Looking wet for NSW/Vic Wed and Thurs Date: Tue, 25 Jan 2000 08:41:23 GMT X-Mailer: Forte Agent 1.5/32.452 X-MIME-Autoconverted: from quoted-printable to 8bit by europe.std.com id DAA07232 Sender: aussie-weather-approval at world.std.com Reply-To: aussie-weather at world.std.com Recent model runs seem to be increasing the amount of rain expected from the trough system moving through NSW and Vic tomorrow and into Thursday. All are in fair agreement, bringing the trough through Sydney late Thurs morning, but vary considerably in where and when surface lows develop in the trough, and where the main focus of rain will be. The latest (00z) GASP develops the surface low over NE SA and brings it SE through central NSW, deepening to around 1000hPa as it gets to the coast, with 50 to 100mm over much of the eastern half of the state. LAPS takes it SE through W Vic, with the heavier rain in S NSW and E Vic. The 00z AVN and NOGAPS don't develop much of a surface low until the trough arrives in eastern Bass Strait. All agree on the main low developing east of Bass Strait Thursday morning. -- Laurier Williams Australian Weather News & Links http://ausweather.simplenet.com +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ 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------------------------------ 013 Date: Tue, 25 Jan 2000 18:17:56 -0800 From: Lindsay [writer at lisp.com.au] X-Mailer: Mozilla 3.0 (Win16; I) To: aussie-weather at world.std.com Subject: aus-wx: USA Winter?

Also, the pattern was not really consistent with dust storms, too many and too small. Dust storms tend to line up along a major wind shift. The cells do match up well with the satellite imagery so I can only suspect that it is picking up the storms but perhaps there is a problem mapping the colour scale to the dBZ levels.
