Dispersion experiments in complex terrain
Meteorologische Zeitschrift, 1994 Nach einer kurzen Übersicht über verschiedene Tracerexperimente in gegliedertem Gelände wird die SF6-Tracertechnik beschrieben, die am Forschungszentrum Jülich für die Sophienhöhenexperimente eingeführt worden ist. Anschließend wird die Anwendung dieser Technik exemplarisch für ein Experiment gezeigt, mit dem das Verhalten von Kaltluftabflüssen an ...

Ensemble Kalman filter assimilation of near-surface observations over complex terrain: comparison with 3DVAR for short-range forecasts [PDF]
Tellus: Series A, Dynamic Meteorology and Oceanography, 2013 Surface observations are the main conventional observations for weather forecasts. However, in modern numerical weather prediction, the use of surface observations, especially those data over complex terrain, remains a unique challenge.
