摘要:Variability and trend of Heat Index (HI) in Thailand during 1975-2017 and their relationshipswith some demographic-health variables were analyzed. Results revealed the spatially coherentand widespread signifcant increase in Thailand’s HI, consistent with signifcant country-widewarming. Thailand’s HI as a whole signifcantly increased by 0.53°C per decade, and it was in thecaution level but will gradually rise to the extreme caution level in the near future. Accompanyingthis trend, the HI distribution and characteristic have signifcantly shifted towards a higherhealth impact level in the recent decades. In addition, year-to-year HI variability signifcantlycorrelated with the El Niño–Southern Oscillation (ENSO) index, providing additional evidencethat ENSO events are an important source of Thailand’s climate variability including extremelyhot weather. Further analysis showed that Thailand’s HI had good positive associations withsome demographic-health variables. These results provide some clues that increasing HI maycontribute to elevated cases of heat-sensitive illness and pose an additional health risk to Thaipeople especially the elder persons which have rapidly grown under the aging society era. Tobetter understand how heat and health in Thailand are linked, however, further detection andattribution studies based on newly available long-term health data are needed.
