| Zusammenfassung |
| We empirically investigate the scaling behaviour of the
horizontal wind along the vertical direction using 287 radiosonde soundings with a
resolution of 50 m. We compare the results obtained with those of the horizontal temporal
behaviour in the framework of Generalized Scaling Invariance and the unified Scaling model
of atmospheric dynamics. We find the scaling to be very well respected over the range 50 m
- 13 km (nearly the entire troposphere) and we estimate the universal multifractal indices
which characterize the statistics in the vertical. By comparing our result with those
obtained in the horizontal we show that the degree of stratification is different for mean
and extreme structures. Finally, we theoretically discuss the necessary improvements to
the Unified Multifractal model needed to account for them. |
