Center for Atmospheric Science and Technology The National Aeronautics and Space Institute (PSTA LAPAN) predicts that in May 2018 there will be a decrease in rainfall in most of Indonesia.

According to Team Member Climate Variability 2018 PSTA LAPAN Erma Yulihastin, it will result in some areas in Java Island experienced the beginning of the dry season. The reason is that along with the consistent Australian monsoon winds that have a dry nature, the peak of the dry season on the island of Java will occur in June 2018.

"While on the equator will experience an increase in rainfall, such as central Sumatra, western and central Kalimantan and in Papua," said Erma Yulihastin to, Saturday, May 19, 2018.

Erma Yuhastin said, based on predicted results of the Conformal Cubic Atmospheric Model (CCAM), Australia's monsoon consistency will weaken in September 2018 and enter the transition season, where there is an increase in rainfall in parts of Indonesia.

Erma said the results of monthly rainfall prediction using CCAM with the initial condition of April 1, 2018 showed a decrease in rainfall in the southern part of Indonesia in April to July 2018 which marked the beginning of the dry season.

Remains Punctuated Little Rain

Nevertheless, in April 2018 on the island of Java there will still be rain, although with a reduced intensity compared to March 2018. Dasarian rainfall March 1, 2018 Erma said, spread along the west coast of Sumatra, Lampung, Java, West and South Kalimantan, Central Sulawesi , and most of eastern Indonesia and Papua New Guinea.

"This is due to the number of convective clouds in dasarian 1," says Erma.

Based on the data of Climate Variability Team 2018 PSTA LAPAN, on dasarian 2, rainfall centered in Eastern Indonesia, the waters southeast of Indonesia, Papua and Papua New Guinea. In this dasarian, rainfall in the area exceeds rainfall in dasarian 1. In dasarian 3, high rainfall is present in the western waters of Sumatra, the waters between Kalimantan and Sulawesi.

However, convective cloud spans appear to be reduced when compared to the previous dasarian and spread over the equatorial region. This is in line with the Madden-Julian Oscillation (MJO) observation that explains that during March, the MJO moved from the Indian Ocean to the Western Pacific Parairan.

"The beginning of March MJO strong enough and continue to weaken when it is above Indonesia until the third week of March," said Erma.

The weakness of MJO when it is above Indonesia causes its influence on weather conditions in Indonesia is relatively small. MJO again increased when it was above the Indian Ocean at the end of March. It is expected that MJO will continue to strengthen in the first week of April and again weaken until the end of April.
