fluid dynamic

Classic

Its just started raining here

Ooh my days this is looking like a dead cert

Mullerred in Motspur Park Waiting for Pub Run

Well thats just greedy, most ladies would be happy with a good 6 to 8 inches. Here's hoping !!!!

Rayning in Raynes Park ? (I like to start with low expectations)

I fully agree, the scatter of results is incredible - hence the record 'shannon entropy' . The resolution of the models and all the precise output completely belies the quality of the analysis in CFD. We have to look at trends and means, nothing else worth looking at. And some of the runs dont even have as much input data as others. All of the errors from T0 compound and run away, far far away into la-la land. Funny to see (some of) the reactions and analysis of single output though. No wonder there are are disagreements on here . Bonkers

Just heard in the office that Penguins have been sighted getting excited in central London in anticipation of the cold spell Oh hang on, that's at London Zoo As you were

interesting stuff (James Madden will be telling us 'i told you so' no doubt)

Looks like it has peaked at 30hPa

thanks for posting that, he says 'probably' a lot, as expected, - but at least he's off the fence. Seems like there is hardly anyone there in that office, maybe last man standing had to do the video !

I reckon its about to top-out, lets see. Tis a biggy, nontheless

Having been lurking since October last year, just joined up. Its fascinating stuff and I have much respect for the obvious professionals (practicing and retired) on Netweather and the large number of amateurs who are well on their way ! The fascination for me is the struggle with the compressible fluids you deal with - I deal with the non compressible variety in models and thank jaysus that I get reliable answers that are borne out in practice. (I am a fast-approaching-middle-age-chartered civil engineer dealing mostly with water infrastructure and treatment). I guess I am a closet warmist as I like to ride my motorbikes and ice is no good for that. If I haven't been banned for that comment and you are still reading, you may be pleased to hear that I also enjoy a bit of cold (ski holiday !) and thanks to your 'wonderful insights and expertise' I put an expensive set of winter tyres on the car in December just before THAT episode The upper atmosphere driving the surface and the link between is newish to me and I am here reading all about. You complain about the flip-flopping of CFD models with compressible fluids? Well we aint going to get any better than that without a significant breakthrough. We have to enjoy it for what it is, its a fabulous area of science and tech with such big implications for us all. Maybe now I've joined I can start an 'ignore' list ? hahahahha , jesting, hi to all of you !
