Abstract：Variables of climate system often exhibit self-similar behavior over different time scales in time series, which is also known as fractal characteristics. Multi-fractal behaviors of the long daily climate variable records in Beijing were analyzed by using multi-fractal detrended fluctuation analysis (MF-DFA). The result indicated that most climate variables exhibit multi-fractal characteristics, but sunshine duration and diurnal temperature range show mono-fractal behaviors in Beijing. We fitted generalized Hurst exponent via a modified generalized binomial multiplicative cascade model and different widths of multi-fractal spectrum are estimated.
