Retrieval of wind fields from Doppler measurements of a single radar and application on a cold front with narrow rain band. Ableitung von Windfeldern aus Dopplermessungen eines Radars und Anwendung auf eine Kaltfront mit schmalem Regenband

Abstract

A method is developed for the retrieval of the horizontal wind vector from Doppler data of a single weather radar. For a horizontal resolution of about 5 km, the accuracy of this method is about 2-5 m/s. This method is applicable for studies of mesoscale phenomena within stratiform precipitation. A cold front with a narrow rainband is studied by this method and additional measurements systems. The wavelike structure of the rainband is caused by wind-shear and stratification within the frontal zone. The cold front passes the Alpine foreland undisturbed, and is retarded by the main ridge of the Alps for several hours. When reaching the Alps, the prefrontal wind field is modified significantly. The speed of the flow is reduced with a simultaneous increase in the cross-flow circulation. (orig.) With 51 figs., 5 tabs., 72 refs.
