If the wxradar ever picked up that info and displayed anything I don't know. If you're interested in pursuing this further, it's easy to extend to include other precipitation info. Basically the concept is that the wxradar gets a very abstract set of data and 'fakes' a plausible display, because if you would acutally display the rain distribution we generate under a storm, you'd see a very nice and utterly unrealistic circle :-) * Thorsten Hm, the wxradar ... couldn’t find that much documentation about it but will do more research in code and property tree, thanks for pointing me to this.

Re: [Flightgear-devel] Weather
Could this weather properties be shared trough network somehow ? No idea, I'm not into MP at all, so I know next to nothing about how easy or difficult it is to transmit anything more. Sorry this dumb questions, I just had the intention to show flightgear weather on a external map/radar and now I need a contemporary way how to get i.e. the thunderstorm data to show. I'm not sure how this is supposed to work. Weather works currently in a rather plane-centered approach, i.e. in Basic Weather the weather everywhere in the sim is how it is at the plane's location (i.e. if you can't see a thunderstorm, there isn't one elsewhere either), Advanced Weather has a limited horizon of 'knowing' the weather in a radius of ~150 km around you. Neither system is in sync with the MP server - you can use any weather you like, online or offline, so in a formation flight one plane can be in bright sunlight whereas the other can be in foggy dawn (just look at the FGUK event screenshots to see how different individual people see weather). It's not clear to me what an external map *should* then be showing if MP use doesn't force same weather for everyone. Could a thunderstorm be shared over network basically ? Or better, should weather be shared trough a RTI federation ? Is there some kind of a weather engine and interface for pilots/teacher/atc already ? There's a lengthy discussion on sharing weather in a rather general context over MP here http://www.flightgear.org/forums/viewtopic.php?f=69t=15516 The consensus seems to be that (with some limitations) this can be done in principle. Just someone would need to do it in practice, and I'm not going to do it because I'm not into MP in the first place, so this seems to be where this is stuck. Hope that helps a bit! * Thorsten -- Everyone hates slow websites. So do we.

Yes, thanks, that helps a bit. I searched the forums for this topic but unfortunately I couldn’t find this thread some time ago. It answers a lot of questions of course. I see some differences to what I’m thinking about, it’s not to share hundreds of cloud positions trough a dedicated distribution system. All I need for the radar (aka map) and a plane to simulate weather condition is some metar-like data, where i.e. you can get the center and movement of a thunderstorm, this storm can be generated and the data can be shared trough network. I don’t know if this makes sense for anyone else, for me it does at the moment. When I read the forum thread I fear my approach is too simple :-( But if this thunderstorm looks exactly the same from different angles is not that important in case there IS a thunderstorm probably. Sharing the center position, pressure, movement, winds and probably cloud density over network is sufficient, in case this data could be shared in metar-like system somehow. AFAIK fg can get metars, probably some simple weather situation can be shared trough artificial metars? So another dumb question, advanced weather is not writing metars, is it? Or more general question, does advanced weather in general deal with metars or is this something that is only used with basic weather? -Yves -- Everyone hates slow websites. So do we.

Re: [Flightgear-devel] Weather
But if this thunderstorm looks exactly the same from different angles is not that important in case there IS a thunderstorm probably. Sharing the center position, pressure, movement, winds and probably cloud density over network is sufficient, in case this data could be shared in metar-like system somehow. AFAIK fg can get metars, probably some simple weather situation can be shared trough artificial metars? So another dumb question, advanced weather is not writing metars, is it? Or more general question, does advanced weather in general deal with metars or is this something that is only used with basic weather? Advanced Weather can parse METAR info and translate it into a weather situation. But the METAR format doesn't include position info on a storm center, a METAR report will provide you the information that there is a thunderstorm somewhere in the vicinity of a weather station, but that's about it. Advanced Weather is not writing METAR info - admittedly I never saw the point why this would be useful, although in theory it could - internally it has all the info needed to assemble a METAR string, so we could generate METAR strings based on the offline weather engine and let airports report those if we like. Advanced Weather manages weather in discrete 40x40 km tiles. A tile has a high level representation (like 'high pressure') as long as it's not generated, when it becomes generated that info is fleshed out, it gets values for pressure, temperature, wind, visibility, light absorption of the atmosphere,... and it gets a large array of all clouds in the tile. The position of any cloud in the tile, specifically also a storm, is generated randomly inside the tile. Dependent on what accuracy you need, there are various options. From simple to complicated: * Simply feeding a METAR string reporting thunderstorms will generate multiple cells of thunderstorms - from the time on when you feed the new string, all subsequent tiles will generate storms till a new report comes in. In this way, you can generate roughly the same weather for all planes approaching a location, but your target region is 100 km sized or so, because you can't precisely control when tiles are built, as this depends on what visibility settings the various MP clients run locally. This should work out of the box. * A more advanced option is to instruct the tile manager to build a special tile when the tile center is close to a pre-defined location. This would allow you to place a storm somewhere in a 40x40 area, but two MP clients might see it in different locations inside this area. This requires ~20 lines of Nasal inserted into the tile manager, including the code which passes the location at which the storm is supposed to appear. * A low level Nasal call like local_weather.create_medium_thunderstorm = func(lat, lon, alt, alpha); will immediately place you a storm at a given location. If Advanced Weather is currently running, all the goodies like turbulence and reduced visibility will work alongside and the storm will drift in the wind. If it isn't running, all you get are the clouds. So there's a simple-to-call function to place a storm at a precise location, but you'd have to write the management structure around it - how is it called, how is it removed, ...? That's probably a few hundred lines of Nasal. * The most advanced option is to do exact synchronization over the MP protocol by exchanging random seeds between clients. That's not so much additional Nasal, maybe a few hundred lines, but requires changes in other places as well. Since I'm not sure what exactly you want to do, I can't really tell you what the best option is.
