Abstract
If vertical turbulent fluxes are computed from time series
collected at a fixed point, it is assumed that the temporal
mean vertical velocity is zero. This paper discusses the
validity of this assumption by analysis of time series of the
vertical wind velocity collected with sonic anemometers
at four different heights ranging from 3 to 180 m from the
Cabauw tower. It is shown that even for averaging times
of 1 hour, the mean vertical velocity can have values of
the order of 10 cm/s.
