Annual minimum temperature projection data for Hong Kong with more details
Annual minimum temperature projection data for Hong Kong with more details |
Following the information provided by the IPCC Interactive Atlas, the Observatory acquired additional 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), a complete set of temperature projections for Hong Kong, including likely range of projection, is computed and shown in the table below. It should be noted that the projections for 2041-2060 and 2081-2100 may be slightly different from the initial projections released in December 2021.
Projected change in annual minimum temperature of Hong Kong relative to 1995-2014 under different greenhouse gas emissions scenarios. Average annual minimum temperature at the Hong Kong Observatory during 1995-2014 is 7.9℃. It should be noted that temperature exhibits regional variation.
