Article Synopsis
- This study analyzed future rainfall patterns in Malaysia’s Johor River Basin using 23 General Circulation Models (GCMs) from CMIP6, comparing them to historical data.
- A novel ranking system (RIM) was used to identify the top-performing GCMs for simulating rainfall, with ACCESS-ESM1-5 and CMCC-ESM2 emerging as the most reliable models.
- Projections indicate increasing rainfall in December, raising flood risks, while August shows a decline, suggesting higher chances of drought, crucial for regional water management and climate adaptation.
This paper aims to select the most appropriate rain-based meteorological drought index for detecting drought characteristics and identifying tropical drought events in the Johor River Basin (JRB). Based on a multi-step approach, the study evaluated seven drought indices, including the Rainfall Anomaly Index (RAI), Standardized Precipitation Index (SPI), China-Z Index (CZI), Modified China-Z Index (MCZI), Percent of Normal (PN), Deciles Index (DI), and Z-Score Index (ZSI), based on the CHIRPS rainfall gridded-based datasets from 1981 to 2020. Results showed that CZI, MCZI, SPI, and ZSI outperformed the other indices based on their correlation and linearity (R = 0.
