Weather - its a conspiracy

[h0ughy]

just looked at the jet stream for NSW area - perfect, tassy and NZ have it all.

But we have cloud :sad:

Considering the unusual and extreme weather all over the world, one would hope that our pollies could at least agree to set some goals for global warming. The jet stream is totally ruining conditions down here; I haven't even bothered getting the scope out for the past few weeks.:tasdevil:

OK explain it for me. What's the difference between 'Jetstream' and 'Cloud'? I always thought Jetsream was just high thin cloud.

[rumples riot]

Jetstream is a stream of air that can travel up to 300kmm/ hour. It is just the air not the cloud. High cloud has all sorts of causes, when people talk about the jet stream they are referring to the stream of air, whether it is not in the area of if it is how violent it will be. On clear nights the jet stream can affect the stability of the seeing. It can make the image dance around like it is in a washing mashing machine.

Hope that clears that up.

Probably wont 'clear' up the problem Paul :lol: (sorry, had to!)


Nice explaination though ;)

Thanks Paul!!!

In other words it can't be seen like cloud can! :confuse3: Grrrr!

[rumples riot]

No it can't be seen Ken, except when we look at planets or stars. The Jet stream should be viewed as an invisible high speed river of air at high altitude that is not bounded by banks; it is free to roam anywhere. Its ability to move make it somewhat unpredictable. Even with the charts. Although it can most commonly be in high concentration when a cold front is present. Then cloud will be seen. However many times cloud and the jet stream are not mutually exclusive.

Anyway, I think you understand my rantings now. We can talk more about this at the camp if you like.

OK! Sounds a bit hard to find it.

Ha, had a wonderful night last night. Bagged 10 deep-sky objects (8 oc and 2 galaxies). But it was cold again (-2°C). I hope I'm not irritating you guys ;).
