Spatio-temporal variation of precipitation spells in Singapore

What is it about?

This paper attempts to investigate the changing characteristics of dry and wet spells of Singapore precipitation in both spatial and time domain in the context of natural climate variability (e.g. ENSO) and climate change. A detailed framework was proposed to characterize the dry and wet spells, and 14 indices were defined to explore the variation of the characteristics. Lastly, the impact of ENSO on wet and dry spell indices was analyzed using a regional regression method. The predicted changes of wet and dry spell characteristics have implication for water resources management in tropical urban cities.
