The present study endeavors to explore the association between total column ozone (TCO) and surface temperature (ST) over Kolkata, India, during September–November through time series approach. A spectral analysis approach is adopted to investigate the existence of any common cycle in TCO and ST time series. The spectra have been computed, and it has been observed that there exist common spectra of period 24 in both the time series explored in daily scale. The existence of common spectra among TOC and ST during the transition period from monsoon to post-monsoon has been interpreted as a proof of the similarity in fluctuation pattern of TCO and ST. Details of the dependence of the variability of TCO on ST have been discussed.

本研究致力于通过时间序列方法探索印度加尔各答9月至11月期间总柱臭氧（TCO）与表面温度（ST）之间的关系。采用频谱分析方法来调查TCO和ST时间序列中任何公共周期的存在。已经计算出光谱，并且已经观察到在以日为单位探索的两个时间序列中都存在周期24的共同光谱。从季风到季风过渡期间，TOC和ST之间共有光谱存在，这被解释为TCO和ST波动模式相似的证据。已经讨论了TCO的可变性对ST的依赖性的细节。
