  1. 4D OMEGA FORM14D-Objective MEsoGamma Analyses of FOehn in the Rhine Valley during MAP Simon Tschannett, Barbara Chimani & Reinhold Steinacker 1 funded by the Austrian Science Fund FWF Project Nr.: P17332-N13

  2. Content • Project Ideas • Data • Analysis Tool • First results Quelle: www.wolkenatlas.de Bad Ragaz Nov. 2004 FORM-Meeting

  3. Project Ideas • Development of 3D - 4D analysis system (with focus on Foehn in the Rhine Valley) • Wind-pressure field interaction • Cross Validation • Comparison of foehn in the Rhine Valley and Wipp Valley • Model Comparison (MM5, MesoNH, MC2) • Intercomparison (on a common grid) • Model - Analysis • Development of Nowcasting tool Bad Ragaz Nov. 2004 FORM-Meeting

  4. Data • Surface stations • Radiosondes • Lidar • Radar • Sodar • Windprofiler • Aircrafts (MAP, AMDARs) • Dropsondes • Constant Level Balloons From MAP-Data-Center, with friendly support by Esther Häller Special Project at ECMWF Bad Ragaz Nov. 2004 FORM-Meeting

  5. Analysis Tool VERAXX • New analysis method similar to VERA  Variational analysis + fingerprints (dynamic downscaling) • Development of new data-quality-control (Bayesian) • Considering of anisotropy in data distribution and in nature in space and time • Calculates on a regular grid • Necessary because of higher dimensions • Using cascading system and nesting Bad Ragaz Nov. 2004 FORM-Meeting

  6. Bad Ragaz Nov. 2004 FORM-Meeting

  7. First Results 2D VERAXX VERA Bad Ragaz Nov. 2004 FORM-Meeting

  8. Air Temperature 15.11.2002 18UTC 3D Horizontal Temperature Cross-Section Vertical Temperature Cross-Section S N Bad Ragaz Nov. 2004 FORM-Meeting

  9. Dissertations • Multidimensional analyses taking non-conventional data sources into account (Barbara Chimani) • Cross-Validation of analyses • Comparison of different data types • Multidimensional analyses for Föhn dynamics research in the Rhine Valley (Simon Tschannett) • Intercomparison of wind and pressure fields • Model comparison (mod-mod; mod-ana) Bad Ragaz Nov. 2004 FORM-Meeting

  10. Next steps • Implementing of 4D and testing of the method with analytical data • Data collection • Testing the analysis technique with real data • Implementing fingerprints and comprehensive data qualitiy control • any questions? Bad Ragaz Nov. 2004 FORM-Meeting
