“we” means anyone working with CFD. It’s been 15-20 years since I did.
CFD (Computational Fluid Dynamics) is often referred to, by “suites” as “Colorful Fluid Dynamics” because of the colorful pictures and animations. Making “porn” is the process of making these colorful animations for non-tech people. “Porn” is a visualization with little or no engineering importance or content, but one that looks very cool.
LeSving, Thank you for clarifying porn for me. Porn in the US usually has XXX attached.
NCYankee how accurate do you find the cloud cover and height forecast for the following (next) day?
This site seems to be doing the rounds of the internet now.
I know a guy who has done some of the work behind it.
It’s a pretty impressive presentation of the winds, though AFAIK it is GFS based so ultimately the forecast will be from that wx model – which is normally pretty good. What I didn’t realise is that you can also see stuff like pressure.
The original post was on xmas day and I guess a lot of people here were busy 
Has anyone used
https://www.windyty.com/
to get forecast ?
Menu → About describes it’s sources
Yes, it’s in my met research bookmarks. Quite useful.
It’s from GFS data, as is this similar one
The accuracy varies, as do all wx forecasts, but it’s a good tool for one’s toolbox, so to speak. It makes it very obvious when bad wx is coming, from the way the winds speed up for example. But regardless the forecast as only as good as the GFS model.
Could be old news to many of you but I just noticed that Windyty now also displays further cloud data that is quite useful to aviators (cloud base, CAPE) and has added ECWMF data, FWIW. Look at the data under the ‘Clouds’ drop-down menu..
There was a post a while ago, pointing to this site which looks a similar sort of thing.
Aart – this is well spotted. I see Windyty now says this
If it means more accurate forecasts that’s great because I have found Windyty no better than a very rough guide, even for immediate flights – despite the amazing graphics. It was just plotting GFS winds, after all.
