Time series analysis of monthly rainfall, mean air temperature and carbon dioxide in Japan

摘要

In this paper, the time series analysis of monthly rainfall, mean air temperature and monthly carbon dioxide in Japan are performed. The forecasting of future values of their time series will be estimated and finally the influence of greenhouse effect from relationship between rainfall or air temperature and carbon dioxide is also investigated. Consequently, from the cross correlation of relationship between air temperature and carbon dioxide, it is guessed that carbon dioxide is influenced by seasonal change and that the pattern of cross correlation is distinguished between summer season and winter season.
