Seasonal Hydrological Drought Indicator for Tropical Drought Identification
Kit Fai Fung, Yuk Feng Huang, and Chai Hoon Koo
Abstract—Drought’s frequency, duration and severity are
essentials for impact control and mitigation of droughts. This
paper adopts 3-month seasonal scale Streamflow Drought Index
(SDI-3) to analyze these drought characteristics for the tropical
climate at the Central, Southern and East Coast regions of
Peninsular Malaysia in 1997-2016. The identified drought
events were then evaluated using four major historical events
from five different locations. The results showed that SDI-3
identified the occurrences of all reported drought events but
with deviated onset and duration. However, the SDI-3 was
concluded to be suitable for hydrological drought monitoring
with reasons of increased temperature, groundwater and forest
replenishment, and human factors. The spatial analysis on the
drought characteristics also showed that most of the areas are
more prone to short-term droughts, with relatively higher
severity at north part of the Central Region, north-west part of
the Southern Region and central part of the East Coast.
Index Terms—Drought characteristics, hydrological drought, spatial analysis, streamflow drought index, tropical climate.
