IOP 13a: Monday, November 1, 1999
 



Gab flow mission in the Wipp Valley (Electra)
The foehn event of IOP13 was well forcasted by the MC2 Model. The forcast shows for the Wipp Valley  a moderate event during the first part of the
day, decreasing during the arfternoon. This reduction of the wind speed is reflectetd by the measurments taken at the airport of Innsbruck (see temperature
and wind speed in METAR below).
Also the  foehn predicted for the Rhine valley was confirmed by the automatic meteo stations in Chur (see ANETZ station Chur below).
 
Surface wind vectors and velocity (knots) in the Rhine and Wipp valley at 08:00 (UTC). Surface wind vectors and velocity (knots) in the Rhine and Wipp valley at 12:00 (UTC). Surface wind vectors and velocity (knots) in the Rhine and Wipp valley at 17:00 (UTC).
