| Zusammenfassung |
This article analyzes the possibility of applying a GOY theoretical model to
atmospheric boundary layer data. Bearing this in mind, relative scaling
exponents of velocity structure functions are used to compare the model with
the data under study. In the model, these exponents are set based on two
parameters (q and δ), which are appropriate to define the model that
better features a certain atmospheric state.
From these scaling exponents, the gap between 2-D and 3-D turbulence is
observed in the model, depending on the fact that δ is higher or lower
than unity, respectively.
Atmospheric data corresponding to very different states of stratification
stability have been analyzed. For convective or near-neutral situations
(usually associated to 3-D turbulence), it is possible to find parameters q
and δ to define a model that fits the measured data. More stable
situations can be featured by GOY models with higher values of δ.
However, it is clear that it is impossible to represent nocturnal situations
of strong stable stratification (with a more similar behaviour to 2-D) with
this type of model. |
