–
Expert Climatology of the National Research and Innovation Agency (BRIN) Erma Yulihastin called the intensity
Rain
will be more heavy and widespread, even when Indonesia is in the middle
dry season
.He said this was due to the warming waters around Indonesia.
“Persistent and rapid heavy rain extends to be the main characteristic of daily rain that fell during the 2nd Dasarian August 2025, especially in the Greater Jakarta area,” Erma said on her Instagram account, Tuesday (12/8).
“Increased rain during the second dasarian (August 11-20) occurs because of the modulation of rain which usually starts from the mountains in southern Bogor, now coupled with an intensive rainy system formed in the Java Sea,” he added.
He said the two things caused the modulation of rain to come from the mountain and sea, which eventually had the potential to worsen the intensity of rain in Jakarta.
According to Erma the formation of the rainy system in the Java Sea does not only have an impact on the western part of Java, but will extend to Central and Eastern Java.
“The impact of the formation of a rainy system in the Java Sea is not even only for western Java but also Central and East Java,” he said.
In addition to convergence, said Erma, the Java Sea can also produce a vortex of the Mesovortex storm which during the second dasarian is experiencing a preconditional phase to form at the end of the second dasarian August.
“Mesovortex now exists in the Java Sea weakened to strengthen, but he exists because there is a convergence system or the wind meeting area formed in the Java Sea now. And later the peak will be on the 19th or end of the 2nd Dasarian August Mesovortex will be large,” he explained.
Climate change
Erma says the climate anomalies that are currently happening are not due to La Nina or negative dipole.He highlighted the absence of anomalies in the Pacific Ocean and the Indian Ocean, the two most influential oceans to modulate and create global climate anomalies.
The cause of climate anomalies that occur in Indonesia, he said, is a warm ocean caused by climate change.
“The cause is Warming Ocean in the waters of our own territory and especially the region in Setio (
Southeastern Tropical Indian Ocean
), then the Java Sea, “he explained.
This warm sea is said to produce maximum evaporation and cause convergence.
Regarding extreme rain that ran out, Erma said that currently the formation of winds that collide with each other so that it forms a vortex of wind.The whirlpool, he said, has a scale that continues to enlarge and even becomes the meso scale.
Furthermore, Erma said the condition of the wet drought will still last until next year, as long as there is no El Nino or positive iod that can affect rainfall.
“We will experience a similar condition like now that the dry season tends
wet anomaly of dry season
(wet anomalies in the dry season), “he said.
