ED Team Yo-Yo Posted March 9, 2011 ED Team Share Posted March 9, 2011 (edited) I see that this feature is not fully documented so I will try to unveil some hints. The main weather field is pressure distribution. In real world this field is formed by areas of high (H) and low (L) pressure calling baric systems (BS). In DCS mission editor (ME) we can set the number of these systems and dominant type. If dominant type is choosen then BS of dominant type will be generated near the centre of the map. If number of BS is greater than 1 other BS will be positioned around the centre. Their position are randomised but statistically they are placed evenly around the centre. Pressure excess is random for each BS. Dominant type of BS affects the average percentage of generated BS of this type. When the pressure field is ready, wind velocity field can be calculated both for altitude and surface winds. Altitude wind directed along isobaric lines and surface wind always additionally turnes towards pressure gradient. As well as pressure field cloud density field is calculated too. As in RL the clouds will be more dense around the L BS. The main problem is that we have not graphic representation for overcast spots, so the places that must be covered with overcast now are covered with our regular clouds.

sobek Posted March 9, 2011 Share Posted March 9, 2011 Am i correct in assuming that the system does not yet create precipitation in areas where this would be likely? Good, fast, cheap.

sobek Posted March 9, 2011 Share Posted March 9, 2011 Does this mean, where it should be overcast there is a problem that means we cannot see those clouds? As that would explain a LOT. ;) I think that is what he means, overcast can ATM only be generated over the whole map or not at all. Good, fast, cheap. Choose any two. Come let's eat grandpa!

ED Team Yo-Yo Posted March 9, 2011 Author ED Team Share Posted March 9, 2011 Am i correct in assuming that the system does not yet create precipitation in areas where this would be likely? As far as I know it does. If the clouds intencity is more than certain value, precipitation is created. Or MUST be created - may be it was turned off for some reasons - I must check.

GGTharos Posted March 9, 2011 Share Posted March 9, 2011 Basically as sobek said - right now overcast is an all-or-nothing graphical effect. You either have overcast everywhere or nowhere. With dynamic weather, you should see more clouds where overcast should be, but it's obviously not overcast still. What Yo-Yo is saying is that in the future they have to come up with a localized overcast effect. Yo-Yo thanks, this is much appreciated.

ED Team Yo-Yo Posted March 9, 2011 Author ED Team Share Posted March 9, 2011 The obvious addition: if you increase number of BS the probability of high gradients becomes higher so the winds get stronger.

winz Posted March 9, 2011 Share Posted March 9, 2011 When I realize how much was improved on the engine since BS v 1.0 (not counting the wonderfull job on the A10C itself), then I cannot wait to see what will happen to the engine in another two years.

GGTharos Posted March 9, 2011 Share Posted March 9, 2011 All hail the hypno-toad :P What I mean is, where you SHOULD have overcast the wind conditions are correct, and so is the pressure, but the overcast graphical effect to represent it visually does not exist.

The main problem is that we have not graphic representation for overcast spots, so the places that must be covered with overcast now are covered with our regular clouds. Well, it just sounds like that all Yo-Yo is saying is that in areas where it should be overcast, very densly placed REGULAR cloud graphics are used rather than the overcast cloud graphic. So it looks overcast, but it's not using hte overcast cloud graphic. That would jive with what I was seeing the other day in a dynamic weather mission. It was, as far as I could tell, overcast in the beginning of the mission at homeplate, but later on, it had cleared. So the regular cloud graphics that Yo-Yo speaks that represent overcast now are so closely spaced it looks like overcast. So don't worry... in places where it should be overcast, it's gonna look overcast. Intelligent discourse can only begin with the honest admission of your own fallibility.

Grimes Posted March 9, 2011 Share Posted March 9, 2011 I've seen quite a few overcast like clouds via dynamic weather. The weird thing I noticed was it seemed to have problems rendering all of them, as the cloud cover over one area wasn't all that heavy, but as I increased altitude toward it clouds "spawned" and it gradually became overcast. I must say I really enjoy playing with the dynamic weather. The only complaint I have with it really is that ya gotta run the mission in order to have an idea what the cloud cover and weather is like throughout the mission area. Just curious, will fog and temperature become dynamic during a mission? The right man in the wrong place makes all the difference in the world.

Weta43 Posted March 10, 2011 Share Posted March 10, 2011 (edited) in areas where it should be overcast, very densly placed REGULAR cloud graphics are used rather than the overcast cloud graphic. ^^ No... Yes... :-) If you set the parameters correctly, you will get high desity 'normal' clouds, that while not solid overcast, can come pretty close. Where you would expect rain, you'll get rain, and where you would expect snow, you'll get snow... Edited March 10, 2011 by Weta43 Cheers. Link to comment Share on other sites More sharing options...
Weta43 Posted March 10, 2011 Share Posted March 10, 2011 I set it to 2 systems, and have the pressure differential betwen the about what you's see as the difference between a couple of systems that are generating some unpleasant weather of the type you're after IRL over about the same distance as you see on the DCS map. if you change the pressure by any increment the systems are re-generated, so just adjust till you get what you're after. once saved they're stable... (that one of the runway loooks pretty good - don't you think ?) Cheers. Link to comment Share on other sites More sharing options...

ED Team Yo-Yo Posted March 14, 2011 Author ED Team Share Posted March 14, 2011 (edited) And a little addition about time-and-spatial turbulence in DCS. I posted these pictures before but I think they could be interesting for new forum members. I think the pictures can make clear some items regarding the turbulence behaviour. http://forums.eagle.ru/showpost.php?p=1138952&postcount=4010 The main point is that the turbulence vectors are correlated if they are taken within the certain interval. The more is the interval the less they are correlated like in RL. This model provides correlation length depending on altitude so the higher you are the smother is the turbulence. I mean not its standard deviation but the deviation between two point at certain distance.

Luse Posted March 14, 2011 Share Posted March 14, 2011 I know that I am asking a very dangerous question with a very vague answer. But.

bfeld Posted March 15, 2011 Share Posted March 15, 2011 Thank you Yo-Yo for the images. When I was reading about the weather engine I was suddenly thinking of exactly these two images, but couldn't find them. Are there any other "debug" screenshots, somehow visualising various engine internals? I'd really like to see more of these. Maybe it's worth a new thread, in case there is a chance to get a little more of these images. I even like images visualising bounding boxes :) Link to comment Share on other sites More sharing options...
ED Team Yo-Yo Posted March 15, 2011 Author ED Team Share Posted March 15, 2011 (edited) More clear visualisation of generated weather than we have now in ME to demonstrate different fields in conjunction. This is a deep cyclone baric system (upper left diagram), winds (upper right diagram) where red lines show winds, blue lines (somewhere) show surface wind and long blue line shows something we have not yet in DCS :) (take a look at the hollow at the pressure surface). The lower diagrams shows the same - cloud distribution.

GGTharos Posted March 15, 2011 Share Posted March 15, 2011 No, it doesn't. Even if it is being kept in mind, it might never end up being planned for, or it might end up being cut. Don't ask about future modules. It's far too early to say anything about them.
