Title : A frequency domain approach to the Surface Temperature and a Statistical Elucidation of its association with Total Ozone Concentration

Abstract:

We endeavor to demonstrate an association between total column ozone (TCO) and surface temperature (ST) over Kolkata, a highly polluted city belonging to the Gangetic West Bengal (GWB). The period, when the study zone experiences a change from monsoon to post-monsoon, is the focus of the study. A spectral analysis approach is demonstrated to study the existence of any common cycle in TCO and ST time series. We have derived the spectra and observed the existence of common spectra of period 24 on a daily scale. We interpret this as proof of the similarity in the fluctuation pattern of TCO and ST. The pattern of the surface temperature has also been studied through Markov Chain to understand its serial dependence to further understand its complexity.
