| Zusammenfassung |
| Modelling the fluctuations of the Earth's surface wind has a
significant role in understanding the dynamics of atmosphere besides its impact
on various fields ranging from agriculture to structural engineering. Most of
the studies on the modelling and prediction of wind speed and power reported in
the literature are based on statistical methods or the probabilistic
distribution of the wind speed data. In this paper we investigate the
suitability of a deterministic model to represent the wind speed fluctuations by
employing tools of nonlinear dynamics. We have carried out a detailed nonlinear
time series analysis of the daily mean wind speed data measured at
Thiruvananthapuram (8.483° N,76.950° E) from 2000 to
2010. The results of the analysis strongly suggest that the underlying dynamics
is deterministic, low-dimensional and chaotic suggesting the possibility of
accurate short-term prediction. As most of the chaotic systems are confined to
laboratories, this is another example of a naturally occurring time series
showing chaotic behaviour. |
