It is shown that the usual method of microturbulent velocity determination from the "abundance versus equivalent width" plot leads to a systematic overestimate of the microturbulent velocity when the observd equivalent widths are affected by random errors. This overestimate is due to the correlation between errors in observed equivalent widths and ...
Fuer viele Aufgaben und Probleme in der Praxis, so z.B. im Flussbau, in der Gebaeudeaerodynamik und in der Landwirtschaft, ist eine genaue Kenntnis ueber die Veraenderungen erforderlich, die eine turbulente Grenzschicht erfaehrt, wenn sie durch ausgepraegte Einzelrauhigkeiten gestoert wird. Dabei interessiert vor allem die Kraft, die durch die Stro...

The influence of terrain surface, terrain shape and buildings on the atmospheric boundary layer flow is examined in three different ways: Through simulation with numeric flow models of the atmosphere, through natural measurements and through wind tunnel measurements. The following phenomena among other things are considered: Questions of flow separ...
