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

I reckon our storm season is going to start with an almighty bang !! The jet around the "Vortex" at 70 Hpa is becoming very ragged: https://earth.nullschool.net/#current/wind/isobaric/70hPa/orthographic=-248.50,-89.25,488 WOW WOW WOW at these: https://www.cpc.ncep.noaa.gov/products/intraseasonal/tem...

Its looking like the strong MJO will go through before the expected September action, but we still have a few weeks to go:

May l recommend you start up your own 'Wordpress' account and publish and save your research there. Its good fun and free. It even downloads and stores your pictures there on their server ................ https://didjman59.wordpress.com/2019/08/20/eddy-heat-flux-anomalies-over-antarctica-winter-2019/

Crikey, up the top of that site is a drop down menu where you can select "eddy heat flux anomalies" :D

Also Crikey, I am saving the heat flux anomaly charts as a sequence for my own learning :D

Zooming in, there is a lot of wind shear attacking the Polar Vortex at both 10 and 70 Hpa: https://earth.nullschool.net/#current/wind/isobaric/10hPa/orthographic=-233.64,-90.11,1363 https://earth.nullschool.net/#current/wind/isobaric/70hPa/orthographic=-233.64,-90.11,782 Looking at the following ani...

Weird Vortex pattern at 70Hpa:

Watching the footy at the G (on TV), and the radar, the radar seems to be over reading on / south of the divide?? Only 3.2mm here so far.

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

Between the 7th and 11th of next month we are forecast to have a strong MJO pulse go through our region. The possibility of some rain is there if it links with any fronts, troughs or lows. If it links with the projected Polar Vortex resulting weather, could be fun times!

Hi 'Didj'. Thanks for your obs' and great enthusiasm Had a look at GFS stratosphere forecasts. Can't see any signs of split at 10 hPa this week. https://www.cpc.ncep.noaa.gov/products/stratosphere/strat_a_f/#emcz The null school windstream looks a tad distorted with a protrusion tonight.But nothing...

The eddie JS referred to yesterday is rising in altitude!
As in the warmest part from 800hpa to 300hpa on the 14th, is now from 800hpa up to 100hpa on the 15th.
