Stationary orographic cloud bands: Dynamic and sportive interests link satellite observations with mesoscale modeling Hans Volkert DLR, Institut für Physik der Atmosphäre (IPA), Oberpfaffenhofen, DE science aspects user & application aspects Outline - 1 Feb 2014 case with clouds as visualization aid -decade-old problem revisited by modern means -conclusions for science/user relation? in memoriam: Joachim KUETTNER 1909-2011 Science director of GATE, ALPEX &c. (cf. SCI-POS 1085 )
1 Feb 2014: MODIS (7-2-1) on TERRA, 10:27 UT FR DE AT CH CZ 20 km 500 hPa, 12 UT Inversion at 600 hPa ~ 4.2 km PL 750 km 500 km 20 m/s
1 Feb 2014: MODIS (7-2-1) on AQUA, 12:12 UT px res. 250 m Innsbruck Jelenica Gora (Hirschberg)
1 Feb 2014: SEVIRI on Meteosat Second Generation Poor man‘s loop: 8 frames at 15‘ intervals 10:30 – 12:15 UT Variable speed loop: 37 frames at 15‘ intervals 07:00 – 16:00 UT on my laptop at poster SCI-POS1085 in room 220D-E Hres VIS px res 1 km
12:15 UT SEVIRI on MSG A L P S Sudety mtns So what ? Described before ?
Short revisit of an 75-year-old publication of 36 pp. one of 35 photogrpaphs
21 May 1937 – vertical velocity in lee of Riesengebirge 20 m/s + + + – – – ~ 8 km one of 11 diagrammes

What about mesoscale modelling ? vertical velocity calculated for 1 Feb 2014 case reference to MAP study
12° 15° 50° 52° Meso-NH: 12 h simulation, VT = 12 UT, Dx = 2 km courtesy of Evelyne RICHARD Realistic simulation: w in z=5000 m (m/s)
cf. MAP case over Eastern Alps: IOP10, 25 Oct. 1999 Meso-NH simulation Dx = 2 km
Concluding remarks Sports people and scientists can share interest Some issues are around for decades New technologies can make things easier Stationarity documented rather than assumed Clouds here markers rather than actors Can glider data be used more as research datasets? Mountains wave cases may be used as testbed for high-resolution mesoscale modelling
