| Zusammenfassung |
| In a recent paper (Koga et al., 2007) it was shown that the intermittent nature of solar
wind turbulence can be characterized by kurtosis and phase coherence index. In this paper,
we apply these two nonlinear time series techniques to characterize
the intermittent nature of atmospheric turbulence above and within
the Amazon forest canopy using the day-time data of temperature and vertical wind
velocity measured by a micrometeorological tower at two different heights. By applying
kurtosis and phase coherence index to quantify the degree of phase coherence, we identify
an enhanced scalar-velocity similarity for in-canopy turbulence compared to the above-canopy turbulence, during the interval of data analysis. |
