storm over africa?

[stuck]

OK, so it may look a bit like an African grassland but it's actually Wimbledon Common. Also despite it being very humid when I took this photo, there was no storm. Still, any excuse for a good tune

Moody!

No storms and no Wombles either!

"God bless the rains down in Africa."
Great tri-colour snapshot.

Were it not for the lowering clouds, that photo might have been taken in my neck of the woods.

We get only 30-33" of rain annually, on average. This far this year we have officially tallied about 8-1/2" which is a deficit of about a foot.

Rain dances aimed in our direction would be greatly appreciated and the result gratefully received.

My dance has begun Bob....

And you'll be able to dance until the end of time.
Possibly.

Wouldn't that be noise pollution?

Thanks, Rudi!

Are reservoirs in RSA now filled?

[Rudi]

Hey Leif,

They couldn't have picked a better song to play till the end of time (or the lifespan of the sun at least!). I love Toto and their hit song: 'Africa'!

Bob. The dams are healthy on our end. It's been raining for two days solid as I write this, so I can expect the Theewaterskloof dam to exceed 80% in a day or two. I am so grateful for the rain, that it is not too little or too much!

Current state of Western Cape Dams. My taps are connected to Theewaterskloof!

Not for Rudi - a good question though.

Don't think so Bob, that's ACDC

About 10 billion years, give or take. Then when it has used up enough of the hydrogen at the core and fused it into helium, it will cool down. The lack of fusion pressure will allow gravity to cause contraction in turn causing helium fusion at the core, pushing the hydrogen fusion to the surface. That process heats the sun up again causing it to swell until the helium ash starts fusing into carbon, then oxygen. The higher temperatures cause the sun to swell up into a red giant, engulfing Mercury, Venus, Earth and Mars. The outer layers will continue drifting off into space leaving a dead white dwarf core surrounded by a planetry nebula.

I'm always fascinated with the science involved in these events and the scale at which it happens. Thanks for the lesson Graeme.

Things that make you go wow!

That'll be quite the storm over Africa then!

Meanwhile back on planet Earth. Part of the walk we did on Wednesday morning took us from Saturn, where saw the Cassini-Huygens probe, to Jupiter.

I'll leave you to search for the route
