Yes. 'didj' . The central vortex is definately looking very nodal. Thanks for the updates.

19th August 2019
The AAO has been negative since July 2019. That’ 46 days in the negative range.
We haven’t seen a long negative phase like this for awhile.
The AAO is currently minus one and forecasts keep the AAO neg until the end of the month.
The westerly belt is contracted north with a well defined meridonal wavy pattern.
There are 4 large nodes today. All extending at least to 30s latitude.
This bodes well for continued cold fronts and westerly belt troughing for the southern quadrant of Australia.
Also continued chances of snow for the alps for the rest of August as cold pools get propelled northward
