Abstract:
Rainfall data are more sensitive to temporal and spatial variations than otherclimatic variables. In this study rainfall data from four different regions of Thrace,Edirne, Kırklareli, Tekirdag and Florya (Istanbul) which observed over a period of 37 years (1970 - 2006) are investigated via nonlinear time series analysis methods to understand the underlying dynamics of rainfall mechanism. The rainfall regime of Thrace can be characterized as partly Mediterranean and partly Black searainfall regime. The method of phase-space reconstruction is used to construct multidimensional phase - space from the scalar rainfall data. A calculated positiv emaximal Lyapunov exponent for each data set indicates a possible chaotic behaviour in the rainfall process.
