Intense High Pressure over southern UK

“From high to low look out below’  

a little warning rhyme from PPL  training about pressure changes.

Which applies, on most of our sims, only to the pressure side of the system...

What I mean is, appart from Aerowinx, the old ( very restricted RTS-Pro now ALSIM ), DCS World and IL.2 Great Battles ( although these two do it in restricted scenarios ), both MSFS and X-Plane completely miss to replicate the effect when under cold weather vs hot weather.

It's because none of these model non-ISA pressure lapse rates... and they do not allow for the injection of pressure gradients, so not even the best weather injectors can overcome that limitation.

Wonder if ASOBO is considering it for MFS ?

...For realism please don’t go near the B key. It only works correctly in areas where the Transition Altitude is 18000ft. ....

i.e everywhere in FSX with the default ATC 😄

Thanks for the tip about Radar Contact - I will have to sit down and watch the tutorials, read the instructions etc. :blush:

I mean, I don't fly "multiplayer" online - not even sure if it works properly on my setup, so I do believe I'm missing out on increased accuracy and immersion offered by RC.

That proves how useless the default ATC is. No realism at all. EHAM TA is 3000ft. Either 5000 or 6000 in the UK. Variety is the spice of life! RC4 is pretty easy to get to grips with and you get the added bonus of me telling you off when you do something you shouldn't! 😁

Pity you don't have P3Dv4. The AIG Ai package brings the world to life and RC4 never stops in busy regions.

I really don't fully understand the mechanics behind all of this - but what does happen with this type of rare event? - lots of snow?

Usually other way round. High pressure tend to dissolve "weather" through subsidence and air diverges on the surface. The opposite can be found on low pressure areas and associated convergence lines where moist air is being thrown uppwards and this thermal activity creates "weather". 

Generally speaking from PPL training only.
