| Abstract: |
The objective of the work is to study the effect of climate change to Hong Kong up to the end of the 21st century.
The study involves downscaling global modelling results to the region around Hong Kong of temperature, rainfall, and sea level predictions for the 21st century for all the climate models used and greenhouse gases emission scenarios considered.
By comparing model predictions to climatological data, the impact of climate change on the annual numbers of very hot days, hot nights and cold days in Hong Kong will be examined for the various decades in this century. Variations of the annual rainfall and frequency of extreme hourly rainfall will be estimated. The impact of sea level rise to the Pearl River Delta, in particular changes in the return periods of extreme sea levels due to storm surge, will be studied using the model predictions and statistical data.
In the second phase, impact of climate change to the health of the local community will be studied.
