Abstract

In the present work we have taken into account the observations of daily temperature and dew point of seven different stations viz. Kolkata, Ahmedabad, Bhopal, Agartala, Mumbai, Chennai and New Delhi. Here the spatial average of temperature and dew point of these seven stations are the signals under observation. A thorough analysis has been made to examine the multifractality and singularity within the signals. The multifractal detrended fluctuation analysis (MFDFA) and wavelet transform modulus maxima (WTMM) based on continuous wavelet transform method are being exploited to serve the present purpose. The results reveal multifractal nature of the present signals.
