What is it about?

We pioneer in exploring urban temperature in Hong Kong using seasonal econometric models. In particular, the characterization of the urban temperature trend was investigated using a seasonal unit root analysis of monthly mean air temperature data over the period of January 1970 to December 2013

Why is it important?

We aims to answer the following question: " How much warmer has Hong Kong’s urban area become during the past four decades?"

Perspectives

The seasonal unit root test makes it possible to determine the stochastic trend of monthly temperatures using an autoregressive model. From the analyzed results, we found that Hong Kong’s urban mean air temperature has increased by 0.169°C per 10 years over the past four decades using monthly temperature data, or 0.174°C per 10 years using annual temperature data, and the trend is likely to persist.
