Abstract

At the beginning of the MAP intensive measurements phase (Sept. 1999), a late summer high-pressure weather system prevailed for nearly three weeks over the Alps. As a result a pronounced valley wind system developed. By means of a wind-temperature-profiler (WTR), the wind and temperature characteristics were measured continuously in the middle of the Alpine Rhine valley near Rankweil. Numerical simulations have been performed with the MM5 model for one selected day (24h cycle of valley wind system), Model calculation and WTR measurements of wind and temperature are in good agreement.
