Drought Analysis Based on Standardized Precipitation Evapotranspiration Index and Standardized Precipitation Index in Sarawak, Malaysia

نویسندگان

چکیده

Drought analysis via the Standardized Precipitation Index (SPI) and Evapotranspiration (SPEI) is necessary for effective water resource management in Sarawak, Malaysia. Rainfall best indicator of a drought, but temperature also significant because it controls evaporation condensation. This study examined drought periods state Sarawak using SPI SPEI based on monthly precipitation data from thirty-three rainfall stations during forty-year period (1981–2020). conditions revealed that both were able to detect temporal variations with distinct time scales (3, 6, 9, 12 months). Taking evapotranspiration into account, was identify more severe-to-extreme area over longer moderate droughts shorter than standard index. According Pearson correlation coefficients, substantial association existed between hydrological dryness. Based results, decisive factor classification, should only be used absence data.

A Multiscalar Drought Index Sensitive to Global Warming: The Standardized Precipitation Evapotranspiration Index

The authors propose a new climatic drought index: the standardized precipitation evapotranspiration index (SPEI). The SPEI is based on precipitation and temperature data, and it has the advantage of combining multiscalar character with the capacity to include the effects of temperature variability on drought assessment. The procedure to calculate the index is detailed and involves a climatic wa...
