Drought analysis and water resource availability using standardised precipitation evapotranspiration index. Atmospheric Research, 201, 102-115.https://repoemc.ukm.my/handle/123456789/1340Trend analysis for potential evapotranspiration (PET) and climatic water balance (CWB) is critical in identifying the wetness or dryness episodes with respect to the water surplus or deficit. The PET is computed based on the monthly average temperature for the entire Peninsular Malaysia using Thornthwaite parameterization. The trends and slope's magnitude for the PET and CWB were then investigated using Mann-Kendall, Spearman's rho tests and Thiel-Sen estimator. The 1-, 3-, 6- and 12-month standardised precipitation evapotranspiration index (SPEI) is applied to determine the drought episodes and the average recurrence interval are calculated based on the SPEI.enPotential evapotranspirationClimatic water balanceStandardised precipitation evapotranspiration indexAverage recurrence intervalJournal
