YOGYAKARTA - El Nino and La Nina are two weather phenomena that have an impact on seasonal conditions in Indonesia. Although both weather phenomena, there are differences between the two. The difference between El Nino and La Nina itself is quite significant and can be felt by the affected communities in Indonesia. This article will discuss both.
The difference between El Nino and La NinaSimply put, El Nino causes Indonesia to tend to be drier, while La Nina makes rainfall increase. However, the difference does not stop there. The following is a complete explanation.
TriggerEl Nino occurs when the sea surface temperature in the central and eastern Pacific Ocean increases above normal conditions. At the same time, the trade winds that usually blow from east to west weaken. As a result, the warm water masses that are usually around Indonesia shift towards the center of the Pacific.
Meanwhile, La Nina occurs when the sea surface temperature in the central and eastern Pacific Ocean becomes colder than normal conditions. This phenomenon is usually accompanied by the strengthening of the trade winds. The strengthening of the winds pushes more warm water towards the western Pacific, including Indonesia.
Sea surface temperatureSea surface temperature is the main indicator in distinguishing these two phenomena. The sea surface temperature of the El Nino phenomenon, the sea temperature is warmer than average. The temperature increase itself can be more than 0.5°C above normal conditions.
If El Nino is synonymous with warming of seawater, La Nina is the opposite. Seawater temperatures are actually colder with a decrease in temperature generally more than 0.5°C below normal.
Rainfall impacts generated in IndonesiaThe difference between El Nino and La Nina that is easily felt by the Indonesian people is the rainfall produced in Indonesia. The El Nino phenomenon has an impact on reducing rainfall in Indonesia, thus triggering a longer drought.
Conversely, La Nina has an impact on increasing rainfall in Indonesia so that the rainy season is more intense. In addition, the frequency of heavy rain is also higher due to La Nina.
Those are some of the differences between El Nino and La Nina. Visit VOI.id for other interesting information.
