Icy airports in the desert

[swampthing]

I made a flight last night from KSTL, where it actually was cold with light snow but had terrain over parts of runways and taxiways. Anyway I take off and get to my destination KPHX and the airport in Phoenix AZ is covered ice yet it was over 50 degrees F. And I had it set to summer. Does anyone know what is causing this?

Thanks in advance

are you using AW and live METARs? one of the options in Environment->environment settings is to set the snow level from the METAR...

Snowcover isn't tightly correlated with temperature - if there's enough snow to begin with, it might last for two weeks with temperatures being above freezing point. Or there might be no snow with temperatures well below zero. The actual snowcover to render depends on the local weather history (which FG can't know) and hence the automatic function is bound to guess wrong fairly often.

Which is why we have a slider to adjust snowcover.

Yes I use live weather wkitty42 and I haven't adjusted the snow levels, I do have advanced weather settings, terrain,effects, terrain presampling, generate thermals and cloud shadows but I have not moved any sliders there I looked at recent weather and it has been 80's during the day and high 40s-50s F at night and no snow/ I don't know what could be causing it. I am using a nightly from 3 or 4 days ago but I wouldn't think it would caused this problem. Never the less, I just spawned in at KPHX and it seems to be as it should.

Thorsten there is a slider for turbulence and by default it is set closer to strong but I haven't experienced any turbulence that I have noticed. Does this function work? I only want it to be realistic as the METAR can make it. Any suggestions here? Should I leave the sliders alone? As far as the ice problem I guess we mark this as solved since there is none at KPHX as I am typing this.

It did last time I checked, but it doesn't generate turbulence on its own, it multiplies it when AW generates some (underneath a T-Storm is usually a good place to look - I've tried to land a Shuttle in a T-Storm last fall, and it was basically impossible) - the reason for the slider is that the same value of turbulence magnitude affects YaSim and JSBSim craft differently so some user input is required.

OK thanks.
