3 Simon TschannettICAM2003 Brig 19.-23.05.20033/10 University of Vienna Department of Meteorology and Geophysics “radiosonde data” and results with VERA (Vienna Enhanced Resolution Analysis) 2 types of anisotropies: data distribution meteorological field (front, inversion)

4 Simon TschannettICAM2003 Brig 19.-23.05.20034/10 University of Vienna Department of Meteorology and Geophysics Result with anisotropic VERA

5 Simon TschannettICAM2003 Brig 19.-23.05.20035/10 University of Vienna Department of Meteorology and Geophysics potential temperature 2km (horizontal) x 250m (vertical) no topography VERAAnisotropic VERA IOP 2b 19.09.1999 18 UTC Heiligkreuz

7 Simon TschannettICAM2003 Brig 19.-23.05.20037/10 University of Vienna Department of Meteorology and Geophysics potential temperature with wind shift of data points IOP8 21.10.99 12 UTC average temperature error over diepoldsau as large as radiation error in stratosphere: 1.6 K  30 gpm error of 500 hPa level

9 Simon TschannettICAM2003 Brig 19.-23.05.20039/10 University of Vienna Department of Meteorology and Geophysics Conclusions Independent cross-sections without model or first guess field Position changes due to wind shift of radiosondes are vital!  Totally different stability parameters  Striking difference in the cross-sections  Wind shifts must not be neglected on the meso scale, this may also apply for model input  Not only 2D cross-sections, but 3D or 4D analyses for foehn studies  Operational distribution of x, y, z, t coordinates of radiosonde data is necessary!
