The Stratobserve site has not updated since 14 July
The scientist who runs the site is aware but is currently writing a paper and won't be able to fix the feed for a few more days.

Re: Climate Driver Discussion 2019 (Enso, IOD, PDO , SAM)

The last and only ever polar vortex split recorded in the SH was in september 2002. Hi Criky, what is your definition of a vortex split? The 2002 event was a full vortex split. As posted at the beginning of the thread, this was a lower stratopsheric vortex split/separation as seen on the observatio...

Re: Climate Driver Discussion 2019 (Enso, IOD, PDO , SAM)

Hi JS, Apart from the polar vortex being "whole" atm, what other pieces are missing? Loving this learning curve btw :D Hi Didjman, IMO, another crucial piece of the puzzle is the Rossby wave or commonly known as the long wave trough. It needs to propagate at the right time into SE OZ to deliver the...

Re: Vic: Fronts and troughs 9 - 19 July

Similar story here, currently on 27mm for the month with the westerly flow. Quite damp though and it will run hard if another tropical feed gets into place before spring. Water storages around here (Coliban water) have jumped to 72%, an increase of 4% from this time last year. Main storage, the Uppe...

Thx for the info JS (learning heaps again :D ) Re the chart, what does "gpm" mean re contour units?
No worries. Gpm is geopotential metres

Re: SNOW FALLS in NSW...Past and present

Nice pic Crikey!

Well spotted Gordon with Spencer creek. Huge jump! Fascinating to observe if it can hit 2 metres again this year. That would be 3 years in a row, which has only been done once since records began in 1954 (years 1990, 1991 & 1992)...correct me if I'm wrong.

Re: Climate Driver Discussion 2019 (Enso, IOD, PDO , SAM).

Hi JS, what exactly are we looking at in that graphic? I have seen it, but am totally confused as to what it is saying:( Also, where do you monitor Tropopause height? Re Tropopause height, I found after some googling that Skew -T charts indicate where the tropopause height is from change in lapse r...

Re: Climate Driver Discussion 2019 (Enso, IOD, PDO , SAM)

Mid to polar latitudes (40 to 80 degrees south) heat flux anomalies now appearing in the upper stratosphere above multiple regions. It seems like another stratospherically induced weak vortex event is now underway from 10 hPa to 100 hPa as per Didjman earlier post when reviewing the NOAA data https:...

Re: Vic: Fronts and troughs 9 - 16 July

25mm for the thread so far. Fairly reasonable considering the west to SW flow.


Nice snow reports from Mt Donna crew. I also see Hotham and Falls over 60cm and Buller 40cm .

Re: Vic: Fronts and troughs 9 - 16 July

Welcome chasersaddict!

More showers moving through, things are ticking over. Access C projecting 20 to 30mm in the next 24 hours locally and big precip totals in the NE ranges. Could be an extra 2 foot of snow for places like Hotham and Falls creek from now to Sunday.

Re: Vic: Fronts and troughs 9 - 16 July

10mm to start things off , 68 km/h was the highest local gust at the airport last night. Looks like Hogan Island in Bass strait wins the highest gust for Vic @135 km/h, 2nd Mt Hotham @124 km/h

Re: Vic: Fronts and troughs 9 - 16 July

Horsham just had multiple 106 km/h gusts. It's only 130m ASL, so it's mixing down nicely from 850 hPa.
