Stratus / T-Storm Clouds in FS Meteo?

Recommended Posts

Has anyone ever had FS Meteo generate anything OTHER than Cumulus layers? I can't recall ever seeing a stratus or t-storm cloud layer created by FS Meteo. I've had FSUIPC generate random rain and lightning "on the fly" in addition adding a cirrus layer on occassion - but never have I seen FS Meteo choose a stratus layer over a cumulus one.What does ActiveSky do here?J

Hmm I was wondering the same thing!! I never see with my FS METEO, i never saw several diffrent cloud layers or thunderstorms!!?? I try to go to places that have bad weather, and i never see cloud layers or a thuderstorm so far?? What give's? Seems like FS METEO is lacking in something?? very strange is that all i get is scattered clouds and overcasts since i got the Updated FS MEteo version! i will try out the weather in KATL and see what FS MEteo gives me, as it seems it's pretty stormy over there!

METAR information contains no data on actual cloud types - only coverage. Although, according to an e-mail I received from Mark, FSMeteo should set a stratus layer for upper level clouds - but I have yet to see that happen. Cumulus every time as far as I can tell. If I want thunderstorms or stratus formations, I must manually set the cloud type(s) from FS's weather dialog.J

If there are thunderstorms, FSMeteo will generate appropriate thunderstorm clouds. I've used FSWSe and installed the killer coloured set and when I flew into an area with thunder stroms, those clouds were generated.

Your in the minority then. I agree with the 1st two gentlemen, I never get thunderstorm data in FSMeteo either.

Mack,Same here. I was flying over Norway on Sunday GMT with current metar (offline mode) that was clearly influenced by the storm-force winds that we has here in the UK, and I was getting big stretches of thunderstorm-like clouds. Will post some pics when I get home tonight !

I also think thunderstorms are generated,but yet have to see some cirrus layers on those nice summer days

i have had thunder stomes... quite a few the trik is the let FSUIPC handle the thunder storme generationlol

FSMeteo won't generate Cirrus either. There's an option in FSUIPC's cloud page which allows random generation of a cirrus layer "when appropriate". As far as I'm aware, this is the only way to get these. I'm wondering if the t-storm layers are created by FS Meteo or by FSUIPC's random storm generator?J

FSMeteo works with METARs and winds aloft data. The only cloud type that I am aware is characterized by METARs is cumulonimbus (CB). If the METAR has a remark about CBs, then I would assume FS2002 (and therefore FSSW) should display thunderstorm clouds (since they are CBs...usually). Stratus clouds, alto-stratus, lenticular clouds and all the rest are not mentioned in the METARs so I doubt there would be an easy way to incorporate them into FS2002 via FSMeteo.

According to Marc, there is such logic (most of it being altitude based) - I just haven't seen it. I'll have to drop in FSSW's colored storm set and then drop in a METAR with a CB code in the remarks and see what happens. Should be pretty clear to see if storm clouds are in fact created.

hmm needs a BUMP, So it seems to me that FS METEO is not all that!! If the METAR stations that FS METEO gets it's info from, that the Metar only gives out some Thuderstorms info, and a few scattered CumUlus clouds,(Don't know if thats the correct type?) And the METAR does not give out any info than that is not good!! I know it gives out high level Wind info, and Overcast clouds, which i see alot, but no cloud Layers etc..........? Don't get me wrong I LOVE FS MEteo!, But with this info you guy's are saying that it has very Limited Weather Info from the METAR Stations, I might want to try out the new Freeware weather makers that some guy's came out recently with? IF they have better info gathering information? does anyone know if they do?? Or can someone clarify what the METAR stations info it actually sends to FS METEO, not just 1-2 types of clouds and Winds?? Thank's for all this new info guy's! MIKE-:)

I don't use FS METEO but I can say from a real world standpoint that METARs generally won't report multiple cloud layers. I believe the standard is that the report stops at the lowest observed ceiling (broken or overcast). There may be other layers above that lowest overcast layer, but they won't show up in the METAR report.Dan

I have the generator switched off. Every time the weather display plug-in indicated "THUNDER STORMS" thunder clouds get generated. I'll try to take a screenshot next time I fly into them.

Hi,As stated, METAR reports do not give cloud type information. They also do not give cloud info above any layer that blocks the measuring equipment, including heavy broken or overcast. Most AWOS equipment that makes METARS at many airports is also limited to 12,000ft AGL for measurements (TAF forecasts have upper altitude cloud layers in the reports).However, it is quite easy to compute the cloud type based on these factors:AltitudeTemperaturePressureFS gives us the choice of CUMULUS, STRATUS, CIRRUS or THUNDERSTORM. We can use the METAR data to guestimate which of these 4 would be most likely to be seen.CUMULUS clouds are generally associated with unstable and/or vertical-movement airmasses. Unstable air that is prone to vertical movement is detected by checking the barometric pressure. Lower pressure = more unstable air. Temperature also affects this. The higher the surface temperature the more prone the air is the vertical movement (warm air rising pushing the unstable air upwards).STRATUS clouds are generally associated with stable airmasses. High pressure assisted with cooler temperatures will provoke the formation of stratus.CIRRUS clouds are composed of ice crystals, and are seen in the upper altitudes where the temperatures are freezing.CUMULONIMBUS (thunderstorm) clouds are basically towering cumulus clouds that generate rain. They require 3 conditions to form: unstable airmass, upward movement of air (to start the formation), and high humidity. Further there are 3 stages of the CB - developing, mature, and dissipating. Each stage is characterized by different movement of air (mostly updrafts in developing, up/down in mature, and down in dissipating).Fortunately, by applying these guidelines and comparing against existing and forecasted weather information, a pretty good picture can be drawn about what the weather will look like. Intelligent cloud type selection based on these factors is only one of the things we can do to make our FS skies more realistic. There are tons of possibilities here that are barely even touched upon yet... But soon we will start to see this. I am working hard on the next version of ActiveSky which will utilize these intelligent selection techniques (current version already does this to a certain degree). I presume that FS2K4 will give us more cloud types and additional manipulation of cloud 'objects' which should really make things tons better.-Damian Clark

No-one seems to have mentioned the following :-Thunderstorms are reported in METARs as TS, TS- or TS+ which means Thunderstorms, Light Thunderstorms or Heavy Thunderstorms respectively. These qualifiers are similar to the rain qualifiers which are RA, RA- and RA+. There are a host of other qualifiers too.These can all co-exist with upto three cloud layers. So, you could in theory get the following elements in the same METAR report :-FEW020 SCT035 OVC070 TS...which would mean a few clouds at 2000ft, scattered clouds at 3500ft, overcast at 7000ft with thunderstorms.There is also the 'VC' qualifier, which means thunderstorms in vacinity.I don't know what FSMeteo decodes and uses, but I do know that X-Plane (along with X-METAR which I wrote) will decode and support all these weather phenomena and more besides.I've never been a fan of FSMeteo, for me it doesn't do anything that the freeware Real Weather & GPS for FS98 didn't do, and this still works flawlessly with FS2002.Chris Ehttp://www.circle-software.co.ukhttp://website.lineone.net/~flightsimukAvoid AGP texturing = Better Performance ;)

I have to agree here. I have often loaded the 'real weather' and has been nothing like the actuals. I can't understand how the sim translates the information, because for most UK/ European airfields the data is meaningless. The viz is always shown as unlimited -if ever, as you say you are lucky if you get more than one cloud layer and I have yet to get rain appearing, even when it is actaully raining. I was interested to see those pictures, they look great. Tell me did the clouds actually have some body, or were they the thin images that you sometimes get?Also where can you get the other weather programs?Thanks,Keith
