On the mountain boundary layer: Diurnal valley winds and exchange processes over complex terrain

Tuesday, 23 January 2018, 16:45-17:45
KIT, Campus Süd, IMK-TRO, Geb. 30.23, 13.OG, Seminarraum
Thermally induced wind systems, such as the diurnal slope and valley winds, are
an important component of the boundary layer over mountainous regions with a
large influence on mountain weather and climate. In current numerical weather
prediction models these winds are often poorly resolved, also their role in
land-atmosphere exchange over complex terrain is unclear. A recent evaluation of
the representation of the valley winds in the Alpine region in the NWP model
COSMO will be discussed, as well as an investigation of heat exchange processes
over complex terrain by means of large-eddy simulation in order to bring light
into the current debate on the valley heating mechanisms.
