David Sandberg - A Weather Question -

Recommended Posts

Hi David,Randall suggested I direct my question to you. The original thread is on this forum at:http://forums.avsim.net/dcboard.php?az=sho..._id=27578&page=under Weather Creation Question.I will quote myself here:"Hi all,I decided to set up a flight plan from Sedona, Arizona to Catalina Island in So Cal.So....using the weather insert tools in the flight planner with the Alt key:I wanted to start off on a clear day and then fly into a cold front. After setting up my route in the flight planner (Sedona to Blyth with a stop in Borrego Air Ranch by the Salten Sea and then on past Oceanside to Catalina).I went from Sedona, clear with no clouds or precipitation, and added some high cirrus clouds at Blyth, increasing clouds halfway from Blyth to Borrego, more clouds, some wind and light rain at Borrego then lots of clouds and moderate rain at Oceanside to heavy rain and a 2,000 ceiling at Catalina.Happy with what I thought I had accomplished, I saved the scenario and went back to my plane in Sedona only to find it cloudy and raining!!!Hmmm...So I clicked on Weather Overview and changed Sedona back to clear. I then went waypoint by waypoint only to find they were all clear too!Frustrated, I decided to teleport to each location, change the weather and save the flight each time...same result! So much for flying slowly into a front!Please help..what am I doing wrong? I left the area effected around the weather at 30 miles, but it did not matter as all the waypoints weather changed to whatever I input at the waypoint I was editing at the time.Thanks in advance,Marc"I await your wisdom and knowledge!

Accidentally posted this in the original question topic, but here it is again:I'm not David, but what you really need to do is set up your own weather METAR file to import into the sim. SInce this is a text file, it isn't all that hard to do. Here is something to try:1. Download latest weather observations from NOAA/NWS into InfoMetar.2. Holding down the SHIFT key, Click on each spot you want to fly (or nearest airport) so a route shows.3. Find and click on the button "thin".4. Once you happy with the points, save the file in Fly!II's METAR folder.5. Now, open the file you saved with notepad and make the changes to each weather observation to what you want over those points and resave. If Borrego Air Ranch doesn't send observations and/or is not shown in InfoMetar, you can still "make your own" by following the format from another observation, and at the beginning, input 5L5 (Borrego's ID) - example:5L5 281953Z 27008KT 7SM SCT033 33/23 A29896. Start Fly!II and load in the specific weather file, and you should have the weather you want only along your flight track. **Do check your altimeter in the Weather/Other dialog box at start to ensure your pressure reading updated correctly.** <--- This I just added. ;-)Hope this helps!Cheers,Ken Wood :-sun1MeteorologistSeawind Projecthttp://www.avsim.com/hangar/fly/dfdg/bannernewkw.jpgGateway 700X; Intel P4 2.4GHz; 512MB RAM; NVIDIA Ti4200 4X AGP 128MB; SB Audigy; Thrustmaster TopGun Fox 2 Pro Shock

I wish I had some great advice for you, but I fear that I really don't. I never did do much of anything with the internal weather creation tools of Fly! ... almost my entire involvement was with the METAR import type of weather. Worse, I never had access to enough of the weather-related source code of Fly! to really be able to test things and find out how all of the aspects of the weather engine were interacting ... in fact I'm to this day still not sure that the code I sent to Richard actually works as intended, because I was never able to see other sections of the code that have to interact with it, and Richard was in no state to be chasing down such details by that point. :(Ken's advice is pretty much the way I'd suggest going as well. (Ken and Randall have both worked with the weather aspects of Fly! enough so that their advice is as spot on as mine could ever be.) The few minor things I'd add are all merely related to InfoMETAR usage:1) If you want to completely synthesize the weather and don't need any of the current live observations, you could change his step #1 to "create random METARs for the entire world by clicking on InfoMETAR's Randomize toolbar button" instead. It would be a whole lot quicker than the download process (primarily the fault of NOAA's FTP weather server), and the random results might very well thin out to a better distribution of stations for you to edit than what you'd get from a live download.2) If you do want to download live weather, but then want to add an observation for a station that doesn't have one, you can get a "template" METAR by right-clicking on the station in InfoMETAR's map and selecting "Randomize Observation" (or something like that ... it's been a while and InfoMETAR isn't on my system right now). That would give you a starting point for editing, at least ... and if you were willing to re-randomize it a few times you might be able to hit upon conditions fairly close to what you want, and hence keep your hand-editing of the results to a minimum.3) Here's a nice little trick: you can get by without editing the METAR file with Notepad if you use the /debug flag to start InfoMETAR, and then press F6, F7 or F8 (can't remember which right now) while the mouse cursor is positioned directly over a station on the map with an existing METAR report. This will pop up a very simple dialog that allows you to edit the correct METAR by hand right then and there. (I hope I'm remembering the command line switch and keystrokes correctly ... it's been a long time and I just reinstalled XP on my machine in the last 24 hours, so I don't have InfoMETAR or much of anything else on my system at the moment. If I'm wrong and this doesn't work, check back with me and I'll get the exact correct process for you once I've got my machine closer to full working condition again.) NOTE: this undocumented /debug feature was only meant for my own testing purposes, so it is not fancy at all and may have undiscovered bugs.I hope the above won't prove to be completely useless. :) Best of luck to you!David Sandberg[br]THE BEAST: AMD Athlon 64 3000+, MSI K8N Neo Platinum MB, 1GB Kingston PC3200 ValueRAM, ATI Radeon 9800 Pro 256MB, WD Caviar SE 160GB, Echo Gina 24/96, Pioneer DVR-107 DVD-RW, Samsung SD-616E DVD-ROM, Antec Sonata case, Mitsubishi 19" Diamond Pro 930SB, Windows XP Professional, DirectX 9.0c, CH USB Flight Sim Yoke & Pro Pedals.[br]Long live InfoMETAR

Thank you for your guidance gentlemen!Looks like I need to get more familiar with InfoMetar. I will let you know how it goes!
