Enhancement of Climate Projections for Hong Kong

21 September 2022

Following the information provided by the IPCC Interactive Atlas, the Hong Kong Observatory acquired data from a number of global climate models that underpin the IPCC Interactive Atlas. Based on this set of climate model data (as at July 2022), the Observatory has computed a complete set of temperature and rainfall projections for Hong Kong, including likely range of projection. This complete set of projection data can be found at the following webpages:
