Abstract
The El Niño–Southern Oscillation (ENSO) event is a climate event that has an impact on the world climate. The effects of ENSO are often associated with prolonged droughts and floods since 1980 following global climate change. In addition to causing flooding and drought. Indirectly, the occurrence of ENSO causes health problems, environmental destruction, affecting economic activities such as agriculture and fisheries. Many studies on ENSO have been conducted. However, there is still a lack of research on the effect of ENSO on temperature in local knowledge areas, especially urban areas because the urban environment especially building materials that can absorb and release heat. In addition, previous studies have focused on large-scale areas. Beside that there still gap to understand and increase knowledge about the effect of ENSO on local temperatures, especially in urban areas. This study uses meteorological data and Oceanic Nino Index (ONI) from 1988 to 2019. This study found that the occurrence of ENSO has an effect on the value of daily temperature but differs based on the value of the ONI index. In addition, this study uses linear regression in predicting the effect of ENSO on temperature. The results of this study are useful to those responsible for understanding the impact of ENSO on temperature in urban areas to provide infrastructure in reducing the impact of ENSO as well as adjustment measures during the occurrence of ENSO.
Highlights
El Niño–Southern Oscillation (ENSO) is a climate phenomenon that occurs in areas in the Pacific Ocean but has a wide impact on weather and climate around the world
The temperature value will increase if the Oceanic Nino Index (ONI) value increases and the meteorological temperature value will decrease if the ONI value decreases
This means that if the ONI value increases the temperature value increases. This can be seen in the El Nino incidents in 1997 and 1998, 2015 and 2016 where the ONI value increased and caused the temperature value to increase
Summary
ENSO is a climate phenomenon that occurs in areas in the Pacific Ocean but has a wide impact on weather and climate around the world. The occurrence of ENSO is often associated with drought and flood disasters (Kovats et al, 2003). The occurrence of ENSO consists of three phases of ENSO known as El Niño (warm tropical Pacific SST), La Niña (cold tropical SST) and Neutral (not El Niño or La Niña) (Chen, 2002). Each episode differs in relative strength, maturity, beginning of season and end, duration and level of SUHU temperature anomaly in the tropical Pacific (Lyon & Barnston, 2005). The El Niño (La Niña) phase is associated with warming temperatures in the tropical Pacific and the Indian Ocean that reduce rainfall in the western (eastern) Pacific region (Allan et al, 2000)
