Effects of climate change on future extreme rainfall indices over Thailand


Maijandee S. et al. View all

Global Environmental Change

Extreme rainfall indices were calculated based on daily rainfall data derived from the outputs of MM5-RCM simulations. Projected changes of these indices in the future (2020s) under the IPCC Special Report on Emissions Scenarios (SRES) A1B compared to the reference period (1990s) were analyzed...
