The difference between hemispheres is even more pronounced at 70HpA Northern Hemisphere 70HpA 05:20 22Jun19 Southern Hemisphere 70HpA 05:20 22Jun19 How did you capture those graphics? I'll pay good money to know. PS: And I need an interpretation of what both indicate ...... please. www.movavi.com/screen-recorder/Low denomination Used notes We are at summer solstice so the Northern Hemisphere is inclined toward the sun and the Southern Hemisphere away from it. For some reason the activity in the upper troposphere has become disordered with meridional jetstreams and jet-streaks with extremely pronounced Rossby waves in both North and South hemispheres. However, at higher 70HpA levels there is a strong vortex in the mid-winter Southern hemisphere and in the Northern hemisphere there is almost no wind activity which possibly explains the different strengths of the jets at lower levels. Why the hemisphere with the lowest energy input has the greatest upper wind strength is difficult. Could it be that the equator to pole heat differential increases the 'heat engine' activity of the atmosphere? Perhaps Acid and Missouri have comments on that.

So, the science sounds a little unsettled?
Should I buy 'Studio' version?

Sitting on my backside on a curb under a shade tree at 30 C with a slow mobile link and no backup is making this hard to visualize. đ. What does N 70 hpa normally look like in June?

Sitting on my backside on a curb under a shade tree at 30 C with a slow mobile link and no backup is making this hard to visualize. đ. What does N 70 hpa normally look like in June? A slightly lesser effect. I have found that Null School allows you to go back to calendar dates (demo below ) As you can see there is similarity but perhaps the Northern jets are less strong this year? YMMV The GIF version is a bit soupy here is a .webm version at higher resolution - www.dropbox.com/s/7qn5qahuirfke4h/Jet_NullSchool_Previous%20Years.webm?dl=0Ratty, I am using 'Movavi Studio' it all depends how many bells and whistles you want

Yow, like non-existent. And 70 Hpa is Stratosphere? Get more summer solar of lower intensity (aka solar minimum) and what happens? Jet circulation disappears at 70 and goes whacky loopy at 500? What are the mechanics of that? CO2 no doubt. âšī¸

No sunlight during polar winter gives large temp gradient compared to temperate regions. Ozone is formed by solar uv and responsible for the increased temp in the strat against the lapse rate. This effect falls off greatly in winter. Wobbly jet is anyones guess, if your a warmist you blame heat, solarists look at the sun. Tho i think it was you Naut who mentioned a spinning top analogy for the jet, its just the scientific description of any mechanism is lacking, ie, what energy affects what to create the observable effect.... Re: polar vortices, the real drama is in its splitting via ssw, a nice tight rotation is business as usual, break it and all hell cuts loose. Not a common southern hemisphere event tho.

www.windy.com/-Temperature-temp?temp,2019-07-04-12,46.119,0.527,5; The European heatwave lasts about a week. It is summer after all. It does occasionally get hot, even in Europe. That being said, a lot of noise has been made about the heat in NW India and Eastern Pakistan. Well, yes, it has been brutally hot there. Been then May and June are by far the hottest months of the year in that region, and stay exceptionally hot until the July monsoons come. Have you ever spent a July in Lahore? I wouldn't recommend it. But, in the world of hyper drive climate alarmism, I'm quite sure we'll soon being hearing frantic stories of how wet it is in India next month. By contrast, the temps in western NA have been below average for weeks, and snow pack in the Rockies and Sierras is many times above average for the time of the year. weather.com/news/news/2019-06-19-sierra-nevada-snowpack-above-average-middle-june-2019.

PS: Miserable rain & cold here in paradise today.
